文章介绍了运用以地质为基础、地物化相结合的综合找矿勘查方法,发现内蒙古东珺铅锌银矿床的过程。通过地质、地球化学和地球物理方法进行找矿勘查,总结出适用于草原和森林景观区浅覆盖-隐伏矿床(体)的勘查流程为:路线地质→大比例尺地质测量和地球化学测量→大比例尺地球物理测量→工程验证;提出基本吻合的1:1万物化探异常可以定位预测隐伏铅锌银矿(化)体,甚低频电磁法和激发极化法对受断裂构造控制的浅覆盖和隐伏脉状铅锌银矿的定位预测是行之有效的地球物理勘查技术方法。根据大比例尺地、物、化示矿信息特征,给出了产于中生代火山岩中的热液脉状铅锌银矿的找矿标志。
The article introduces the process of discovering the Dongjun lead-zinc-silver deposit in Inner Mongolia by using the integrated prospecting and exploration method which is based on geology and geophysics. Geology, geochemistry and geophysical methods for prospecting exploration concluded that the exploration process suitable for shallow cover - concealed deposits (body) in the grassland and forest landscape area: route geology → large-scale geological survey and geochemical survey → large scale Geophysical surveying → engineering verification; 1: 10,000 common geophysical prospecting anomalies can locate and predict the latent lead-zinc silver ore body, the very low frequency electromagnetic method and the induced polarization method can control shallow faults and concealed faults controlled by faults Prediction of vein lead-zinc-silver deposits is an effective geophysical prospecting method. According to the features of large-scale, physical and chemical information, the prospecting marks of hydrothermal vein-like lead-zinc-silver silver ore produced in Mesozoic volcanic rocks are given.
