内蒙古小孤山锡锌多金属矿的矿床地质特征与找矿意义

内蒙小孤山锡锌多金属矿是产于燕山期花岗斑岩与下二叠统大石寨组含碳质岩石接触带的热液成因矿床。该矿床没有地表露头,完全依靠大比例尺的地球化学土壤测量结合激电中梯、电阻率测量发现异常后进行钻探验证查明的。该矿床的查明为在大面积第四系覆盖区和地台区寻找隐伏矿体提供了有益帮助。

Inner Mongolia Xiaogu Shan Sn Zntin-metalliferous ore is a hydrothermal deposit which is produced in the contact zone of the Yanshanian granite porphyry and the carbon rock from Lower Permian Dashanzhai Group. The deposit has not appeared on the earth surface. It was found and verified totally by the large-scale geochemical soil survey, explosive electron middle grads technique and resistivity tests. The identification of the deposit is useful for finding out the concealed mineral deposits in the large Quatema~~ covered areas and platform areas.
