摘要：

蒙古南戈壁地区在寻找斑岩型铜多金属矿方面取得丰硕成果。位于该地区东延长线上的二连浩特—东乌旗地区虽开展了多年勘查和研究工作，但未能实现铜多金属矿的勘探突破，因此，确定两者是否属于同一成矿带具有非常重要的意义。文中在系统分析该问题研究背景、现状的基础上，通过对比分析该地区航磁特征、遥感影像特征和部分地区布格重力异常特征，认为二连浩特—东乌旗地区与其相邻的蒙古东南部地区构成相对独立的构造成矿单元，其西、北边界为北东向延伸的宗巴音—头道桥—鄂伦春断裂，而受宗巴音深断裂控制的南戈壁成矿带往北东方向延伸，与二连浩特—东乌旗多金属成矿带不属于同一成矿带。因此二连浩特—东乌旗地区应具有自己独特的成矿规律和成矿条件。

Abstract:

 Since many porphyry copper deposits have been discovered in South Gobi of Mongolia， recently a series of research and exploration work has been done in the ErenhotDongwuqi region. However， no breakthrough has been made in the exploration of copper deposits. Hence， it is of great significance for exploration to determine whether the ErenhotDongwuqi region and South Gobi belong to one polymetallic metallogenic belt or not. According to the comparative study of aeromagnetic characteristics， remote sensing images and some bouguer gravity anomaly in some areas， here we demonstrate that ErenhotDongwuqi region and South Gobi form different and independent tectonic units. The northwestern border of ErenhotDongwuqi region is the NEstrike ZongbayinToudaoqiaoElunchun fault. The South Gobi polymetallic metallogenic belt controlled by the Zongbayin fault extends in the direction of northeast， which  not belongs to the same metallogenic belt as ErenhotDongwuqi region. Therefore， ErenhotDongwuqi region should have unique metallogenic regularity and conditions.

Key words:  Polymetallic metallogenic belt, Fault Connection, South Gobi, ErenhotDongwuqi
