摘要
为深入研究卫宁北山地区的航磁资料,提取弱磁异常信息,对该区前期的航磁资料进行延拓、化极等处理,对磁异常做出了新的解释,分析了该地区多金属矿床(点)、矿化带与磁异常的关系,结合重力异常资料、电磁测深结果,做出磁性基底受控于近东西向构造,隐伏中酸性岩体是引起弱磁异常的磁源体,也可能就是多金属矿的物源体的推断,并预测了深部成矿远景区。
This paper has dealt with the aeromagnetic data in the Bsishan Mountain of Weining,studied the characteristics of magnetic and gravity anomalies and explained buried rocks in the study area and analyzed the relationship of polymetallic deposits and mineralizations to magnetic anomalies in the Beishan Mountain of Weining.With the data of electromagnetic sounding,the deep ore-forming prospect area is predicted.
