内蒙古新巴尔虎右旗地区磁异常特征及成矿预测

通过1：5万地面高精度磁法勘探工作，笔者分析了测区局部磁异常和区域磁异常的展布特征，总结了主要地质单元的磁场特征，并圈定磁异常14个，解译断裂构造16条、火山通道7个.根据各异常体、断裂以及火山通道的展布特征，结合异常区内的地质条件，对圈定的14个磁异常进行了综合解释，并推测C1、C12、C13磁异常是寻找多金属矿的有利靶区；C4、C9、C10、C12和C14磁异常具有形成多金属矿的良好地质条件.

MAGNETIC ANOMALY AND METALLOGENIC PREDICTION IN THE XIN BARAG YOUQI AREA,INNER MONGOLIA

With the 1:50000 high-accuracy ground magnetic prospecting, the authors analyze the distributing features of local magnetic anomaly in the survey area and regional magnetic anomaly, summarize the magnetic field features of major geological units, delineate 14 magnetic anomalies and interpret 16 fault structures and 7 volcanic conduits. Combining with the geological conditions, the article comprehensively interprets the 14 magnetic anomalies and infers that C1, C2 and C13 magnetic anomalies are favorable targets for polymetallic ore prospecting. The C4, C9, C10, C12 and C14 magnetic anomalies have good geological conditions for formation of polymetallic ores.
