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.
