[0059] Example 1

[0060] The disclosed embodiment provides a method for evaluating the mineralization scale of porphyry copper deposits.

[0061] For details, see Figure 1 , the methods for evaluating the scale of porphyry copper deposits include:

[0062] Step S101, collecting rock samples from the area to be investigated, and separating zircon single minerals from the rock samples.

[0063] Specifically, the collection methods include trenching, drilling and tunnel sampling. By sorting out stable zircon single minerals from the collected rock samples, it is convenient for analysis and calculation, and can quickly evaluate the scale of porphyry copper mineralization in the area to be explored.

[0064] The step of separating zircon monominerals from the rock sample comprises:

[0065] Physically sorting the rock sample to obtain single mineral particles;

[0066] Performing cathode luminescence imaging on the single mineral particle to obtain a single mineral particle image;

[0067] Zircon single mineral is sorted out according to the single mineral particle diagram.

[0068] Specifically, the physical separation of zircon single minerals is to break large rocks into particles of about 3 cm in size, wash and dry them, and then break them into 60 meshes. Non-magnetic heavy sand minerals are screened out by manual washing and electromagnetic sorting, and then large particles with complete crystal forms are selected using binoculars. Figure 2 , Figure 2 For the cathode luminescence image of igneous zircon provided in the embodiment of the present application, the single mineral is glued to a round target made of epoxy resin for cathode luminescence imaging to obtain a single mineral particle image, and pure, complete large-grain zircon is sorted out through the single mineral particle image for subsequent elemental analysis.

[0069] Step S102, performing element analysis on the zircon single mineral and the rock sample, and establishing an element database.

[0070] The step of performing element analysis on the zircon single mineral and the rock sample and establishing an element database comprises:

[0071] Obtaining acquisition data of the rock sample and the zircon single mineral;

[0072] Performing major element analysis and trace element analysis on the rock sample, and performing trace element analysis on the zircon single mineral, to obtain oxide contents corresponding to the elements in the rock sample and the zircon single mineral;

[0073] An element database is established based on the collected data, the rock sample and the oxide content of each element corresponding to the zircon single mineral.

[0074] It can be understood that the collected data includes the data source of the rock sample mineral, the name of the ore deposit, the name of the sample, the sampling coordinates, and the age of the sample. The oxide contents of silicon, titanium, aluminum, iron, manganese, magnesium, calcium, sodium, potassium, phosphorus, etc. are obtained by performing major element analysis and trace element analysis on the rock sample. The oxide contents of lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, etc. are obtained by performing trace element analysis on the zircon single mineral. As shown in Table 1, Table 1 shows the database of the method for evaluating the mineralization scale of porphyry copper deposits provided in the embodiment of the present application. The database is established in the form of a table, which also includes the loss on ignition, vanadium and scandium of the rock sample.

[0075] Table 1

[0076]

[0077]

[0078] Step S103, screening the element database according to preset indicators to obtain target element data.

[0079] The preset indicators include the weight of loss on ignition, the weight of aluminum oxide, and the Rittmann index. The step of screening the element database according to the preset indicators to obtain target element data includes:

[0080] The target element data with a loss on ignition weight of less than 3.5%, an alumina weight of less than 20% and a Rittmann index of less than 3.3 in the element database are screened out.

[0081] Preferably, target element data with a weight loss on ignition of less than 3.5% in the element database are screened out to exclude interference from hydrothermal alteration. Target element data with a weight of aluminum oxide less than 20% are screened out to exclude interference from the accretion effect. The Rittmann index is an index representing the relationship between the total alkali content and the silicon dioxide content in igneous rocks. The content of sodium oxide and potassium oxide in magma is usually referred to as the total alkali content. The calculation formula of the Rittmann index is (Na2O+K2O) 2 / (SiO2-43), where Na2O, K2O and SiO2 represent the weight percentages of sodium oxide, potassium oxide and silicon oxide in the rock, respectively. According to calculations, if the Rittmann index is less than 3.3, it is called calc-alkaline rock; if the Rittmann index is greater than 3.3 and less than 9, it is called alkaline rock; if the Rittmann index is greater than 9, it is called peralkaline rock. In this way, calc-alkaline rock samples with a Rittmann index less than 3.3 are screened out.

[0082] Step S104, calculating the mineral deposit scale index of the area to be explored based on the target element data, wherein the mineral deposit scale index includes V / Sc of rock and Eu / Eu* of zircon.

[0083] The step of calculating the mineral deposit scale index of the area to be explored based on the target element data comprises:

[0084] Calculating V / Sc of the rock according to the target element data, wherein V / Sc represents the ratio of vanadium content to scandium content in the rock;

[0085] Calculate Eu / Eu* of zircon according to the target element data;

[0086] The calculation formula of Eu / Eu* of the zircon is:

[0087]

[0088] Sm is the samarium content, Eu is the europium content, Gd is the gadolinium content, Sm N 、Eu N and Gd N Element-normalized values ​​for samarium, europium, and gadolinium, respectively.

[0089] Specifically, based on the differences in chemical characteristics shown by the existing ore-forming rock mass and the non-ore-forming rock mass, these differences indicate that the ore-forming magma has a higher water content than the non-ore-forming magma, and the ore-forming magma has a higher oxygen fugacity than the non-ore-forming magma. Oxygen fugacity refers to the effective oxygen partial pressure, and the oxygen partial pressure refers to the partial pressure of oxygen under the total pressure of the mixed gas. And high oxygen fugacity is a universal feature of porphyry copper deposits. Therefore, this embodiment represents the water content of the ore-forming magma by selecting the V / Sc of the rock, and represents the oxygen fugacity of the rock by selecting the Eu / Eu* anomaly of the stable zircon monomineral. The ore deposit scale index is constituted by two indicators, namely, the magma water content of the rock and the oxygen fugacity of the rock. By performing single mineral analysis and calculation after systematic sampling of the rock mass in the area to be explored in the early stage of exploration, the scale of porphyry copper deposits in the area to be explored can be quickly evaluated to determine whether to further invest in the exploration project, thereby reducing the exploration risk in the later stage.

[0090] Step S105, evaluating the mineralization scale of the porphyry copper deposit in the area to be explored according to the ore deposit scale index.

[0091] The step of evaluating the mineralization scale of the porphyry copper deposit in the area to be explored according to the ore deposit scale index comprises:

[0092] Whether the porphyry copper deposit in the area to be explored is mineralized can be determined based on the size of Eu / Eu* of zircon, and the scale of porphyry copper deposit in the area to be explored can be calculated based on the V / Sc of the rock.

[0093] The step of judging whether the porphyry copper deposit in the area to be explored is mineralized according to the size of Eu / Eu* of zircon includes:

[0094] Determining whether the Eu / Eu* value of the zircon is greater than or equal to the mineralization threshold;

[0095] If the Eu / Eu* value of the zircon is greater than or equal to the mineralization threshold, it is determined that the porphyry copper deposit in the area to be explored has mineralization potential;

[0096] If the Eu / Eu* value of the zircon is less than the mineralization threshold, it is determined that the porphyry copper deposit in the area to be explored does not have mineralization potential.

[0097] Specifically, the Eu / Eu* value range of zircon in porphyry copper mineralization rock bodies around the world is counted, and Eu / Eu*=0.3 is set as the mineralization threshold. This mineralization threshold is used to determine whether the area to be explored has mineralization potential.

[0098] The step of calculating the mineralization scale of porphyry copper deposits in the area to be explored according to the V / Sc of the rock comprises:

[0099] The formula for calculating the mineralization scale of porphyry copper deposits in the area to be explored based on the V / Sc of the rock is:

[0100] Y=0.0704*e 0.3086x ,

[0101] x is the ratio of V / Sc, Y is the porphyry copper mineralization tonnage in the area to be explored, and e is a natural constant;

[0102] If Y is greater than 0.5, it is determined that the area to be explored has the exploration potential for large-scale porphyry copper deposits;

[0103] If Y is greater than 0.1 and less than 0.5, it is determined that the area to be explored has the exploration potential for medium-sized porphyry copper deposits;

[0104] If Y is less than 0.1, it is determined that the area to be explored has no exploration potential.

[0105] Specifically, copper deposits with reserves greater than 500,000 tons are called large copper mines, and copper deposits with reserves between 100,000 and 500,000 tons are called medium-sized copper mines.

[0106] The method for evaluating the mineralization scale of porphyry copper deposits provided in the present embodiment comprises the following steps: collecting rock samples from the area to be investigated, and separating zircon monominerals from the rock samples; performing elemental analysis on the zircon monominerals and the rock samples, and establishing an element database; screening the element database according to preset indicators to obtain target element data; calculating the ore deposit scale index of the area to be investigated based on the target element data, wherein the ore deposit scale index includes V / Sc of rock and Eu / Eu* of zircon; evaluating the mineralization scale of the porphyry copper deposit in the area to be investigated according to the ore deposit scale index, and by screening the element database with preset indicators, representative mineralization rock body data can be obtained, and by substituting the ore deposit scale index into the ore deposit scale index, the mineralization potential and scale of the porphyry copper deposit can be evaluated more accurately, thereby reducing investment costs, improving exploration efficiency, and reducing exploration risks.
