Abstract: The present disclosure provides a method for determining an ore-forming environment of a porphyry deposit based on a tourmaline component, including the following steps: collecting a tourmaline-containing rock in the porphyry deposit to obtain a rock sample; performing pretreatment on the rock sample to obtain a treated sample; performing an in-situ tourmaline trace element test on the treated sample to obtain a test result; performing data processing and interpretation on the test result to obtain tourmaline trace element data; establishing a discrimination factor based on the tourmaline trace element data; and determining the ore-forming environment based on the discrimination factor. The present disclosure can quickly recognize a forming environment of a newly discovered porphyry deposit, thereby summarizing a rule and quickly giving guidance for a next prospecting direction.

Abstract: In a method for discriminating deposit types by using tourmaline elemental components, contents of Sn, Li, Ga, and V trace elements are determined by collecting hydrothermal tourmaline samples in a deposit, and deposit type discrimination is performed with F1, F2, and F3 as discriminant factors, in combination with the characteristics that a porphyry type Cu—Mo—Au deposit has lower contents of Sn+Li, and further, a porphyry type Cu—Mo deposit has higher contents of Ga*V, while a porphyry type Au deposit has relatively low contents of Ga*V; a granite-related Sn—W deposit has relatively high contents of Sn+Li; while an IOCG deposit has relatively high contents of Sn+Li and Ga*V, realizing quick discrimination of the deposit types during prospecting and exploration, shortening the exploration period and reducing the exploration cost, and the method can be used for identification of 4 different types of deposits.

Abstract: A method for rapid prediction of porphyry copper mineralization potential based on spectral characteristics of tourmaline, includes collecting and collating data related to magma-fluid evolution, petrography and mineralogy of a porphyry copper deposit in a working area, systematically, distinguishing magmatic tourmaline from hydrothermal tourmaline in the working area, and further distinguishing phases and generations of the hydrothermal tourmaline; collecting hydrothermal tourmaline samples of the same phase and generation; performing short-wave infrared spectroscopy measurement on the collected hydrothermal tourmaline samples; extracting spectral characteristics of the Fe—OH wavelength and Mg—OH wavelength of the tourmaline samples based on The Spectral Geologist (TSG); and when the Fe—OH wavelength is less than 2245.75 nm, and the Mg—OH wavelength is greater than 2356.

Abstract: The present invention discloses a method for evaluating a metallogenic potential of a skarn deposit based on the magnetite composition, including collecting geological, geophysical, geochemical, and remote sensing data in a studying area, systematically, and delineating a favorable area for mineralization; collecting magnetite-bearing samples in the favorable area for mineralization, and describing the lithology, alteration and mineralization characteristics of each sample; selecting the most representative magnetite samples for chemical analysis to obtain average contents of trace elements Ti, Ni, V, K and Al+Si+Mg, denoted as c(Ti), c(Ni), c(V), c(K), and c(Al+Si+Mg) in ppm; and calculating discriminant factors F1, F2, F3, and F4 by substituting data, and performing discrimination; and when the four discriminant factors all discriminate the metallogenic potential to be better, determining the skarn deposit in the favorable area for mineralization to have a good metallogenic potential; and discriminating as
