陕西安康沈坝金矿成矿地质特征及找矿前景分析

Analysis of Geological Characteristics of Mineralization and Prospecting Prospects of Shenba Gold Deposit in Ankang City,Shanxi Province

安康沈坝金矿位于南秦岭褶皱系南缘,安康北部志留纪岩金矿成矿带中部,矿体呈似层状、透镜状贮存于早志留世梅子垭组地层中,受韧性剪切带控制,其成矿与韧性剪切带时空、成因有密切联系,矿区金矿床应属于韧性剪切带蚀变岩型金矿。

The Shenba gold deposit in Ankang city is located in the south margin of the southern Qinling fold system and in the middle part of the Silurian gold metallogenic belt in northern Ankang city.The ore bodies are layered and lenticularly stored in the lower Silurian Meiziya formation and controlled by ductile shear zone.Its mineralization is closely related to the time-space and genesis of ductile shear zone.
