吉尔吉斯布丘克金矿床地质特征及成因探讨

Geological characteristics and genesis discussion of Buchuk gold deposit in Kyrgyzstan

布丘克金矿床位于吉尔吉斯中部,中亚造山带的北天山与中天山结合部,矿体受NWW-NEE向韧脆性剪切带控制。本文通过综合分析布丘克矿床成矿地质背景,矿区地质特征、矿石特征、围岩蚀变等,初步厘定其矿床成因为韧性剪切带型金矿床,其深部和外围具有较大的找矿潜力,并提出了对本区该类型金矿床的找矿标志。

Buchuk gold deposit is located in the middle of Kyrgyzstan,where the North Tianshan Mountains and the Middle Tianshan Mountains of the Central Asian Orogenic Belt connect.The orebodies are controlled by NWW-NEE trending ductile-brittle shear zone.Based on a comprehensive analysis of the ore-forming geological background,geological characteristics,ore features and wall rock alteration of the Buchuk deposit,the genesis of the deposit is preliminarily determined as a ductile shear zone type gold deposit,with great prospecting potential in its deep and peripheral parts,and the prospecting criteria for this type of gold deposit in this area are put forward.
