Description

Technical Field

[0001] The present application relates to the field of geology, and in particular to a method, device and electronic device for describing a geological body. Background Art

[0002] A geological body is a product of geological action that occupies a certain space in the earth's crust and has a certain composition that can be distinguished from the surrounding objects. It can be anything from a piece of rock to an inclusion. Geological bodies record important information about the history of the earth and are also important investigation and research objects of geological surveys. Through the observation, analysis and research of geological bodies, we can understand the material composition of geological bodies, analyze the material sources of geological bodies, and further study the terrestrial body to which the geological body belongs and the regional geological evolution history, laying the foundation for research on plate movement, material migration in the earth's interior, and mineralization.

[0003] Investigation and description, test analysis, research summary, and results expression are the four main steps of geological survey work. In the two steps of investigation and description and test analysis, the collection and analysis of geological data are mainly completed, and the accurate acquisition of various geological bodies in the regional scope is realized; the research summary is based on objective data, through comprehensive scientific research comparison, law summary and in-depth analysis to obtain comprehensive research results, and constantly refine and correct the expression of results, and complete the drawing and expression of the final geological map in the stage of results expression. According to the process specifications of geological survey work, geological bodies are drawn on geological maps after field observation. Geological maps can give a general overview and quickly understand the regional geological profile, the distribution, age, direction and other related geological body information of geological bodies, so there is a saying that "one picture is worth a thousand words". With the continuous enrichment of geological science work means and research methods, in addition to displaying geological bodies, topography and other geological elements through geological maps, accurate and detailed descriptions of geological bodies are also required in the process of research summary, presentation of reports and exchanges, and writing of research reports, so as to provide standard, detailed, and intuitive comprehensive descriptions for geological body research, communication, and expression. These contents cannot be directly obtained from geological maps, and scientific researchers need to continuously summarize and refine them to obtain them.

[0057] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0058] A method and device for describing a geological body according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0059] First, some concepts in this application are explained.

[0060] 1. Geological body: usually refers to a product of geological action that occupies a certain space in the earth's crust and has its own inherent components and can be distinguished from the surrounding materials. Regardless of its size range, whether it is as large as a rock body or as small as an inclusion, it can be called a geological body. In geological maps, geological bodies can often be expressed as a surface-shaped patch element.

[0061] 2. Terrane: The full name is tectonic stratigraphic terrane, which is a geological entity bounded by regional faults, with regional extension, and with a completely different geological development history from the adjacent terranes. Terrane is a collection of a series of geological bodies. The geological elements in one terrane have different historical development laws or causes from those in other terranes.

[0062] 3. Geological map: A geological map is a comprehensive carrier for expressing the results of geological survey work. It expresses geological survey phenomena, research conclusions, test results, etc. on a geological map in a certain scale by using colors, symbols, text and other legends, thereby showing the correlation, spatial distribution and other characteristics of geological bodies.

[0063] In addition, the main data used in this method include two categories: one is geological data, including geological body data and mineral resource data and structural fracture data within the region; the other is geographic topographic data, including administrative area data (provinces, cities, counties, villages), DEM elevation data, transportation data (roads, railways, airports), and water system data (rivers, lakes), all of which are stored in the database of the geographic information system (GIS).

[0064] Figure 1 is a flow chart of a method for describing a geological body according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0065] Step 101, extracting the terrain element from the geographic information system, calculating the boundary, minimum enclosing rectangle and center point of the terrain element, and dividing the minimum enclosing rectangle into eight quadrant orientation areas by four designed directional line segments based on the coordinates of the center point.

[0066] In the embodiment of the present application, this step involves geometric calculation of terrain elements, and specifically includes the following steps:

[0067] Step 1: For the extracted terrain element TerA, extract its boundary to obtain a set of terrain coordinate inflection points.

[0068] In one embodiment of the present application, a certain terrestrial element TerA is retrieved from a geographic information system, the boundary of the terrestrial element is extracted, and a set of terrestrial coordinate inflection points is obtained.

[0069] It should be noted that the geographic information system is able to call and load various types of data that need to be analyzed, realizing the loading process of multi-source data, in which the database contains various geographical and geological data used in this application.

[0070] Step 2: Get the maximum horizontal coordinate X among all the inflection point coordinates (X, Y) in the inflection point set of the earth body coordinates max , minimum horizontal coordinate X min , maximum ordinate Y max and the minimum ordinate Y min , and construct the minimum enveloping rectangle Envelope TerA .

[0071] Step 3: Perform geometric operations on the terrain element TerA, calculate the center point of the terrain geometry and extract the center point coordinates (C x , C y ), the expression is:

[0072]

[0073] Among them, (x i ,y i ) are the coordinates of each node of the terrain geometry, and n is the number of nodes.

[0074] Step 4: Use the center point coordinates (C x , C y ) as the center, respectively for the smallest outer rectangle Envelope TerA The four vertices intersect, and four directional line segments of 45°, 90°, 135° and 180° are constructed. The minimum enveloping rectangle Envelope is obtained through these four directional line segments. TerA The image is segmented and eight quadrant orientation regions are constructed.

[0075] Among them, the eight quadrant direction areas can be recorded as: northeast east, north northeast east, northwest west, northwest west, southwest west, south southwest west, south southeast east and south east east.

[0076] Therefore, the geometric calculation and regional segmentation of terrain elements are realized through the above steps.

[0077] Step 102, extracting all geological body data sets belonging to terrestrial body elements, selecting a geological body element from the geological body data set, and performing geometric calculations on the geological body element to obtain the extension trend and area of ​​the geological body element.

[0078] In the embodiment of the present application, this step involves geometric calculation of geological body elements, and specifically includes the following steps:

[0079] Step 1: For the extracted terrestrial element TerA, the boundary range of the terrestrial element TerA is calculated, and the boundary range is used to perform superposition analysis with all geological body data to extract a set of all geological body data GeoDS belonging to the terrestrial element TerA.

[0080] Step 2: traverse the geological body data set GeoDS, obtain a geological body element Geoi as the target geological body element, obtain the geometric shape of the geological body element, and calculate the mass center point PG of the geological body element Geoi based on the geometric shape of the geological body element Geoi eoi .

[0081] Step 3: According to the geometric shape and mass center of the geological element Geoi, obtain the coordinates of all inflection points of the geological element, and construct the minimum circumscribed rectangle Envelope of the geological element Geoi according to the coordinates of all inflection points of the geological element Geoi , and calculate the minimum enclosing rectangle Envelope Geoi The length of the long and short sides.

[0082] It should be noted that in the embodiment of the present application, the minimum circumscribed rectangle Envelope of the geological body element Geoi is constructed according to the coordinates of all the inflection points of the geological body. Geoi The process is similar to that of constructing the minimum enveloping rectangle of the terrain in step 101. TerA The process is similar to that of FIG. 1 , and will not be repeated in this application.

[0083] Step 4: Minimum Envelope Geoi The long side of is taken as the advancing direction (X direction or Y direction), and moves toward the end point with a step length of 1 / 50 of the long side, and draws perpendicular lines to the boundary of the geological element Geoi in sequence to obtain all the intersection points of the boundary of the geological element Geoi and the perpendicular line each time it moves.

[0084] It should be noted that the step size of the movement can be adjusted according to the actual scenario, and this application does not make too many restrictions.

[0085] In a possible embodiment, all intersections of the boundary of the geological body Geoi and the vertical line during the movement are as follows: Figure 2 As shown, the dark dots are intersection points and the light dots are calculated midline points.

[0086] Step 5: Calculate the average values ​​of the horizontal and vertical coordinates in the non-moving direction (short side direction) according to the number of intersection points, and record the coordinates P of all non-moving directions. j .

[0087] In the embodiment of the present application, j is the number of the coordinate, and its maximum value is not greater than the total number of moving steps.

[0088] Step 6: Connect all coordinate points in the non-moving direction into line segments in sequence to obtain the geometric center line of the geological element Geoi, and extract the coordinates of the two end points of the center line. Use the coordinates of the end points to calculate the general strike angle of the geological element Geoi, thereby extracting the extension strike and area of ​​the geological element.

[0089] Therefore, the geometric calculation of geological body elements is realized through the above steps.

[0090] Step 103, determine the position of the geological body element in the eight quadrants, the distance to the center point of the body, the overall terrain characteristics of the area, and the spatial relationship with the water system, transportation network and administrative division.

[0091] In the embodiment of the present application, this step involves the spatial relationship calculation of geological body elements, which specifically includes the following steps:

[0092] Step 1: Overlay the geological element Geoi with the constructed eight quadrant orientation areas, obtain the polygon of the intersection of the geological element Geoi and each quadrant through the intersection operation with the eight quadrant orientation areas, calculate in which quadrant the polygon with the larger area in the intersection polygon is located, and determine the theme orientation of the geological element Geoi by the area ratio method.

[0093] In the embodiment of the present application, for each quadrant, the polygons intersecting with it can be extracted from the results of the overlay analysis. Each intersecting polygon represents the distribution of geological elements in the quadrant, and then the area of ​​each intersecting polygon is calculated. This is to quantify the distribution of geological elements in different quadrants, and finally identify the intersecting polygon with the largest area, and the quadrant in which it is located is the main orientation of the geological elements.

[0094] Furthermore, in order to more accurately determine the orientation of the geological element Geoi, the area ratio method can be used. This involves calculating the ratio of the area of ​​each intersecting polygon to the total area of ​​Geoi. If the area ratio of the intersecting polygons in a quadrant is the largest, the direction of the quadrant can be regarded as the main orientation of the geological element Geoi.

[0095] Step 2: Use the calculated mass center point P of the geological element Geoi Geoi The distance between the geological element Geoi and the geometric center point of the terrain is calculated.

[0096] Step 3: Overlay the geological element Geoi with the terrain data DEM, use the geometric boundary of the geological element to extract the terrain data DEM, calculate the elevation information of the terrain characteristics of the area where the geological element Geoi is located, and use the extracted DEM to calculate the slope and slope aspect information to obtain the overall terrain situation of the area where the geological element Geoi is located.

[0097] In the embodiment of the present application, the elevation information mainly includes the average elevation, the maximum elevation and the minimum elevation.

[0098] Step 4: Perform spatial operations on the geological element Geoi and the water system data to calculate whether the geological element Geoi contains or cuts the water system element. If so, record the name of the water system.

[0099] Step 5: Calculate the geological element Geoi and the traffic road data to determine whether the geological element Geoi contains or cuts the road data. If so, record the road name. If no road crosses the road, use the proximity analysis method to calculate the road closest to the geological element Geoi and its location.

[0100] In addition, according to the actual scenario, transportation elements such as railways and airports can also be added for calculation.

[0101] Step 6: Use the spatial inclusion relationship to calculate and determine the relationship between the geological body element Geoi and the administrative area of ​​the region. If the administrative area is included, it will be recorded. If the relevant administrative area is not included, the distance and direction to the nearest administrative area will be calculated.

[0102] It is understandable that regional administrative areas include cities and villages.

[0103] Therefore, through the above steps, the spatial relationship calculation of geological body elements is realized, and the position of geological body elements in the eight quadrants, the distance to the center point of the body, the overall terrain characteristics of the area, and the spatial relationship with the water system, transportation network and administrative division are obtained.

[0104] Step 104, determine the contact relationship between the geological body element and its surrounding geological bodies and collect rock combination data of the geological bodies in contact with it, obtain the rock combination and diagenetic age of the surrounding geological body data in contact, and eliminate Quaternary sediments and stratigraphic data.

[0105] In the embodiment of the present application, this step involves the analysis and statistics of the geological body elements and the rock composition of the geological body in contact with them, and specifically includes the following steps:

[0106] Step 1: Determine the contact type of the geological body around the geological body element Geoi through spatial adjacency, and collect the geological body data in contact with it.

[0107] Among them, the contact types of geological bodies are divided into contact and non-contact.

[0108] Step 2: Traverse the data of the contacted geological bodies, extract the rock combination and diagenetic age of each geological body, remove the Quaternary loose sediments and strata, and record the rock combination and diagenetic age of the extracted geological bodies in geological chronological order.

[0109] Therefore, through the above steps, the rock data analysis and statistics of the geological body elements are realized, the contact type of the geological body around the geological body is obtained, and the rock combination and diagenetic age data of the surrounding geological bodies in contact are recorded and counted.

[0110] Step 105, compile a geological body comprehensive information description grid model, and automatically generate a comprehensive description text of geological body elements and comprehensive information statistics of rock combinations in contact with the geological body based on the information obtained in the above steps and combined with the analysis and calculation results.

[0111] In the embodiment of the present application, firstly, according to the terrestrial body to which the geological body belongs and the terrestrial orientation, the area and extension direction of the geological body, the overall characteristics of the terrain and topography of the geological body, the location of the internal and surrounding administrative regions of the geological body, the water system and road accessibility, the rock characteristics and formation age of the geological body, and the contact relationship between the geological body and other geological bodies and the rock combination and diagenetic age information statistics, a comprehensive description text of the geological body elements and the comprehensive information statistics of the rock combination of the contacting geological bodies are automatically generated, and a comprehensive information description grid model of the geological body is compiled.

[0112] Then, according to the various results calculated in steps 101 to 104, the geological body comprehensive information description grid model is automatically generated and filled to form an accurate comprehensive description of the geological body elements.

[0113] In a possible embodiment, a geological body description example is:

[0114] The No. 2 (geological body ID code) geological body "AA (geological body name)" belongs to the terrane "TerB" (terrane name), located between 42°~42°01′2″N and 18°3′~18°3′10″E. The main body of the geological body is located in the NNE area of ​​the "TerB" terrane, and part of the geological body passes through the NW and NE areas of the "TerB" terrane, about 56 kilometers away from the geometric center of the "TerB" terrane. The geological body extends in a northwest-southeast direction as a whole, with an extension angle of about 330°, and the geological body area is about 2.6 square kilometers.

[0115] The average altitude of the area where the geological body is located is 168 meters, the highest altitude is 177 meters, and the maximum height difference is 15 meters. There are two main rivers passing through the geological body, namely the perennial river RiverA and the seasonal river RiverB. There is no road passing through the geological body. The nearest road RoadNaA is located in the southwest of the geological body, about 0.6 kilometers away from the geological body, and there are no railways, airports, ports and other ancillary facilities within 10 kilometers of the geological body. It is about 8 kilometers away from the nearest administrative village VillageA, which is located in the southeast of the geological body.

[0116] The main rock components of this geological body are: hornstone, marble, garnet, phyllite and calc-silicate rock, with an age of about 815 million years. According to the information statistics of the geological bodies in contact with the surrounding geological bodies, this geological body has contact with 17 surrounding geological bodies, including loose sediments and strata of the Quaternary. The rock combinations of the main contact geological bodies are shown in Table 1 in chronological order.

[0118]

[0119] In summary, this application proposes a method for describing geological bodies, and establishes a model that can comprehensively and accurately describe geological bodies. First, geometric calculations are performed on the elements of the terrestrial body to obtain the eight quadrant orientation areas, and then the geometric calculations and spatial relationship operations are performed on the elements of the terrestrial body to determine the general extension trend of the geological body, the position in the eight quadrants, the distance to the center point of the terrestrial body, the overall characteristics of the terrain in the area, and the spatial relationship with the water system, transportation network and administrative area. Then, the surrounding geological bodies of the geological body elements are analyzed and counted, and finally, by compiling a comprehensive information description grid model of the geological body, combined with data extraction and spatial analysis calculation results, the normalization, standardization and automation of the description of the geological body are realized, which greatly improves the efficiency and accuracy of the research on the geological body. In addition, this method is suitable for regional geological surveys and research of various scales, and can play an active and important role from scientific research in small areas to large-scale investigations and research. This description method is not only applicable to the field of geology, but its principles and method models also have extensive reference value in other scientific fields that require accurate description of complex natural elements.

[0120] In order to implement the above embodiment, the present application also proposes a geological body description device.
