摘　　要：在论述中蒙边境成矿带地质构造演化与金成矿关系的基础上,研究分别由华力西期侵入岩、韧性剪切带、华力西期火山活动及晚古生界二叠系(以格根敖包组和大石寨组为标志)控制的金矿床类型,初步探讨了其找矿方向,认为该带找金的重点在东乌旗以西的阿巴嘎旗—苏尼特左旗—苏尼特右旗一带,成矿时间主要为晚古生代,构造以韧性剪切带和层间滑脱拆离带为主,以华力西期中酸性侵入岩、火山—次火山岩与金成矿关系最为密切。Based on the discussing of the relationship between geological structure evolution and gold mineralization of metallogenic belt in China-Mongolia border,we research the gold deposit types,which are controlled by Varisean intrusive rocks,ductile shear zone,Variscan volcanic activity and Permian.We think preliminary that gold prospecting should focus on the Ukraine Abagaqi-Sunitezuoqi-Suniteyouqi area whose mineralization age is mainly late Paleozoic,tectonic is ductile shear zone and inter-layer slippage detach.Varisean intermediate-acid intrusive rocks volcanic and sub-volcanic are closely relationship with gold mineralization.
