Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 Shown, the specific implementation steps of the present invention are as follows:

[0021] (1) Select geological elements and analyze the buffer zone under the GIS environment; according to the geological characteristics of the area where the deposit is located, determine the possible influence range of the geological elements, so as to determine the width and buffer distance of the buffer zone. Buffer analysis can be realized with the help of commercial GIS software such as ArcGIS, such as figure 2 Shown is a schematic diagram of the buffer zone of a fault structure, the buffer distance is 1km, ...

Abstract

The invention discloses a method for measuring the spatial relationship of a geology element and an ore deposit on the basis of a fractal method. The method comprises the following steps: (1) carrying out buffer zone analysis on the geology element; (2) carrying out statistics on an ore deposit number contained in each buffer zone; (3) calculating a specific value of an accumulated ore deposit number and the width of the buffer zone to obtain ore deposit space distribution density; (4) plotting on a bilogarithmic graph: setting an X shaft as the width of the buffer zone and an Y shaft as the ore deposit space distribution density, utilizing a least square method to fit a data point to obtain the slope of a straight line, and subtracting 2 from the slope of the straight line to obtain the singular index of ore deposit distribution; and (5) comparing the singular index of the ore deposit distribution, and judging the significance of the geology element. The method is suitable for the spatial relationship of the geology element and a geological resource event and also can be used for measuring the spatial relationship of the geology element and a geological disaster event.

Description

technical field [0001] The invention relates to the technical field of earth science, in particular to a method for measuring the spatial relationship between geological elements and mineral deposits based on a fractal method. Background technique [0002] Correct understanding and description of the spatiotemporal distribution of mineral resources, effective acquisition of mineral resource information, and reasonable information synthesis and modeling are the keys to mineral forecasting. With the development of metallogenic prediction theory, the geological information required to be processed is more and more comprehensive and holistic. The combination of geological, geophysical, geochemical, remote sensing and other multi-source data, that is, the fusion and analysis of multi-source geoscience data information is increasingly used in metallogenic prediction research, which plays a guiding role in future ore prospecting work . The key to quantitative evaluation of minera...
