运用定量解释方法剖析磁异常——以大板金矿区C₆磁异常为例

摘要: 运用定量解释方法对大板金矿区C₆磁异常进行剖析,查明异常原因,说明在特定条件下,根据物理场特征比较,运用定量解释方法搞清异常体的空间赋存状态(形状、产状、埋深),可以区分矿异常与非矿异常.此外,通过实际应用效果比较,对高磁适用的几种简便、快速的定量解释方法进行了评价,证明三角系解释法是一种简捷、实用、值得推广的方法.

Abstract: The method of quantitative interpretation is applied in analysis of the C 6 magnetic anomaly in Daban gold field to find out the cause of the anomaly.It is possible to understand the occurrence (shape,attitude and depth) of the anomalous bodies by quantitative interpretation,and then distinguish ore-caused anomaly from non-ore-caused anomaly,under specified conditions,on the basis of characteristic comparison of physical fields.An assessment is made on several easy and quick methods of quantitative interpretation that is suitable for high magnetic anomalies.By comparing the practical effects,it is proved that the triangle system interpretation is a simple,functional and worth to be popularized method.
