中文摘要:
      航磁异常在夜长坪钼钨矿床(隐伏矿床)发现过程中起到了首发作用(首先发现),地磁测量对磁异常进行了细化。文章通过对夜长坪钼钨矿床典型磁异常二维反演不同方法的分析,并采用软件正演计算所采用的参数,表明磁性体采用经验切线法进行的反演计算是较为可靠的,验证了磁性体是产状近于直立略微南倾的三度体—板状体或椭球状体。
英文摘要:
      Aeromagnetic anomalies played a primary role in the discovery of the Yechangping Molybdenum tungsten deposit(hidden deposit)(first discovered), and geomagnetic measurements refined the magnetic anomalies. Through the analysis of two dimensional inversion methods of typical magnetic anomalies in the Yechangping Molybdenum tungsten deposit and the parameters used in software forward calculation, it is shown that the inversion calculation of magnetic bodies using empirical tangent method is more reliable. It is proved that the magnetosome is a third body-a plate or an ellipsoid-that produces a shape close to the vertical slightly southward inclination.
