阿城区二道岭铅锌矿床成矿物质来源浅析

Analysis of ore-forming material source of Erdaoling Pb-Zn deposit in Acheng

二道岭铅锌矿床处于小兴安岭-张广才岭多金属成矿带的南部地带,且在秋皮沟—五道岭成矿带亚带。其矿床特征、成矿母岩地球化学特征等表明其为矽卡岩型矿床,本文通过对其侵入岩与矿体硫同位素及金属矿物的包裹体测温来揭示该矿床的成矿物质来源,为该区域的进一步找矿提供依据。

Erdaoling Pb-Zn deposit is located in the southern part of Xiaoxing'anling Zhangguangcailing polymetallic metallogenic belt and the sub zone of Qiupigou-Wudaoling metallogenic belt.The characteristics of the deposit and the geochemical characteristics of the parent rock indicate that it is a skarn type deposit.In this paper,the source of ore-forming materials of the deposit is revealed by measuring the sulfur isotope of intrusive rocks and ore bodies and the inclusion temperature of metal minerals,so as to provide the basis for further prospecting in this area.
