西秦岭阿芒构造蚀变型金银铅锌多金属矿地质特征及找矿标志

Geological features and prospecting criteria of the Amang tectonic alteredAu-Ag-Pb-Zn polymetallic deposit in West Qinling Orogen

西秦岭位于南北和东西构造转换地带,构造演化复杂,成矿条件优越,已发现多处中小型金银矿床和矿点。本文在收集已有地质资料的基础上,分析阿芒金银铅锌多金属矿矿区和矿体地质特征,提出了矿床成因机制和找矿标志,可为后期西秦岭造山带西北端成矿规律认识和找矿勘查提供基础地质资料。

The West Qinling Orogen is located in the north-south and east-west tectonic transition zone,with complex tectonic evolution and superior metallogenic conditions.Many small and medium-sized gold and silver deposits and occurrences have been found.On the basis of fully collecting the existing geological data,this paper analyzed the geological features of the Amang gold-silver-lead-zinc polymetallic deposit and ore body,and put forward genetic mechanism and prospecting criteria of the deposit,so as to provide basic geological data for understanding the metallogenic law and prospecting exploration in the northwest end of the West Qinling orogenic belt in the future.
