| 摘 要： | 1017高地银铅多金属矿区是近两年在内蒙古自治区锡林郭勒盟东北部发现的一处岩浆热液型银铅多金属矿, 大规模的地质普查和综合性研究工作正在进行之中。燕山晚期中粗粒黑云二长花岗岩和中细粒黑云二长花岗岩是主要矿源层, 褶皱和断裂提供了成矿空间。岩体中构造破碎带、构造角砾岩, 具有各种蚀变和矿化的地质体, 物探激电中梯测量圈定的极化率异常区和可控源音频大地电磁测深圈定的低阻地质体都是寻找银铅多金属矿的重要标志。1017高地具有形成大中型银铅多金属矿床的成矿条件。

| Abstract: | Ag-Pb polymeta llic m ining area of highland 1017 is a kind ofmagmatic hydrothermal Ag-Pb polymetallic deposit found in the northeast part of Xilinguole league, Inner Mongolia. Large-scale geological survey and comprehensive research for it are in process. The major source beds are medium-coarse and medium-finegrained biotite adamellite of late Yanshan era, the folds and faults structure provide spaces for the polymetallicm ineralization. The important indicators of finding Ag-Pb polymetallic ore include structure fracture zone and tectonic breccia inrocks, the geological body with a variety of altered andm ineralized, the polarizab ility anomaly area delineated by the geophysical IP intermediate gradient, and the low resistivity geological body delinaeated by controllable source audio-frequency magneto telluric sounding. There are the ore-controlling factors for large ormedium Ag-Pb polymetallic ore in high land 1017. |
