内蒙古苏尼特左旗东苏金矿地质特征及矿床成因

The Inner Mongolia Sunitezuoqi Dongsu Gold Geological Features and Deposit Genesis

内蒙古苏尼特左旗东苏金矿矿体赋存于中元古界志留-泥盆系下统温都尔庙群组绢云石英片岩、绿泥石英片岩与流纹斑岩脉接触部,受北东向挤压破碎构造制约,并叠加岩浆期后热液动力,属挤压破碎蚀变岩型金矿床。研究其矿体地质特征及成因,对该矿区外围及周边寻找金矿提供基础的地质依据。

The Dongsu gold deposit in Sunitezuoqi, Inner Mongolia occurs in the contact of sericite quartz schist, chlorite quartz schist and rhyolite porphyry vein in the Lower Silurian-Devonian Wenduermiao Group of the Mesoproterozoic, which is restricted by the NE-trending compression-fragmentation structure and superimposed post-magmatic hydrothermal power, it belongs to the compression-fragmentation altered rock type gold deposit. Studying the geological characteristics and genesis of its ore body can provide a basic geological basis for finding gold deposits in and around the mining area.
