鲁西夏家小河构造蚀变型金矿地质特征及找矿标志

Geological features and prospecting criteria of Xiajiaxiaohe tectonic-alteration-type gold deposit in western Shandong Province

沂沭断裂带是的郯庐断裂带重要组成部分,地质条件复杂,成矿条件优越,已发现多处中小型金矿床和矿点。本文在充分收集已有地质、物探资料的基础上,分析鲁西夏家小河金矿矿区和矿体地质特征,提出了矿床成因机制和找矿标志,可为后期沂沭断裂带两侧成矿规律认识和找矿勘查提供基础地质资料。

As an important part of Tan-Lu Fault Zone,Yishu fault zone had complex geological conditions and superior metallogenic conditions,and many small/medium sized gold deposits and orebodies were found.On the basis of adequate collection of the existing geological and geophysical data,this paper analyzed the geological and orebody geological features of Xiajiaxiaohe gold deposit in western Shandong Province,and proposed the genetic mechanism and prospecting criteria of the deposit,which provided basic geological data to understand metallogenic regularity and to prospect on both sides of Yimu fault zone in future.
