摘要
与韧性剪切带有关的金矿床是阿尔泰南缘原生金矿的主要成矿类型之一,通过对科克萨依、赛都、多拉纳萨依等三处与韧性剪切带有关之典型金矿床的研究对比,总结了区内与韧性剪切带有关金矿的基本成矿特征与找矿标志,探讨了成矿物质来源,认为韧性剪切带是成矿的前提。
The Au deposit related to ductile shear zone is one of the main types of primary Au deposit in the south margin area of Altay .The authors make a correlative stuty on Kekesayi,Saidu and Dolanasayi which are typical Au deposits related to ductile shear zone in the area and generalize the characteristics and prospecting creteria of such type of Au deposit. The sources of ore are discussed and it is considered that ductile shear zone is the prerequisite and sedimentary clastic rock and Au-bearing low metamorphic volcanic clastic rock formations are the favourable setting in late palacozoic arcs for formation of such Au deposit.
