| 摘 要： | 当杖子铁矿是被中上元古界长城系地层覆盖的全隐伏矿床,通过对其进行地面磁法测量,获取直接的磁异常数据,圈定了磁异常范围,得出异常极大值为750nT。通过各种物探解释方法,确定了深部隐伏矿体的分布和空间产出特征,为矿床勘探提供了较为明确的地球物理数据。经钻探验证,该矿床为赋存于盖层之下的大型铁矿床。

| Abstract: | Dangzhangzi Iron Mine is a concealed mineral deposit covered by Upper Proterozoic Changcheng strata. Through magnetic survey of ground, we can get the magnetic anomaly data (great value 750 nT) and delineate the magnetic anomaly scope. Through a variety of geophysical interpretation methods, we can determine the distribution and spatial characteristics of deep concealed ore which provide explicit geophysical data. After drilling verification, the deposit is hosted in a large iron deposit under the cap. |
