摘    要:赛坝沟地区的金矿床主要受近平行展布的嘎顺-乌达热呼韧性剪切带控制,区内金的活化、迁移受控于与矿床所在韧性剪切带,金矿体主要赋存于韧性剪切带的脆-韧性转换位置。根据包裹体测温、稳定同位素特征以及岩石地球化学等资料分析,成矿物质主要来自本区滩间山群绿片岩,其成因是与绿片岩有关的韧性剪切带型金矿床。

关 键 词:赛坝沟  断裂控矿  造山带  韧性剪切带

Abstract:The gold deposits of Saibagou area are mainly controlled by the nearly parallel Gasun-Wudarehu ductile-shear zone while the activation and migration of the gold are controlled by the ductile-shear zone within the area where the gold deposit is located in. In addition, the golden ore body is mainly preserved in the brittle-ductile transitional part. According to the analysis about tefiaperature of fluid inclusions, characteristics of stable isotopes, and geochemistry of rocks, the metallogenic materials are mainly from greenschist. So the Au ore deposit is relative to the ductile-shear zone.
Keywords:Saiba ditch  fracture over the ore-forming  orogen  ductile-shear zone
