摘要
本文在探讨新疆北山地区区域重、磁场特征的基础上,系统地叙述了北山裂谷内发育的白地洼、磁海重力高异常特征和基性、超基性岩体群重、磁场特征。指出坡北、笔架山岩带处于EW、NEE、NNW三组断裂所控制的三角形重力高的梯度带和负磁异常带上。提出通过这一特点,可以在北山地区寻找新的基性、超基性岩体群和拔矿靶区圈定。
Based on the regional gravitational and magnetic prospectings in Beishan area of Xinjiang, the authors describe systematically the gravity high anomalies in Baidiwa and Cihai within Beishan Rift, and gravitational and magnetic features of basic and ultrabasic rock bodies. It is shown that the pobei and Bijiashan rock belts are controlled by the triangonal gravity high gradient belt and negative magnetic anomaly belt formed by NW, NEE and NNW trending fractures. Therefore it is possible to find new basic and ultrabasic rock bodies, and to define the prospecting target.
