| 摘 要： | 山西孤山铁矿是被长城系高于庄组白云岩和第四系覆盖的全隐伏矿床。通过地面高精度磁法测量,获取了磁异常数据,圈定了磁异常范围,磁异常总体呈NE走向,长约4000m,平均宽约800m。通过化极、不同高度的延拓处理和拟合反演,根据异常特征结合地质资料分析,确定了隐伏磁铁矿的分布和空间特征,为矿床进一步勘探和开发提供了地球物理依据。

| Abstract: | Gushan Fe deposit is a fully hidden deposit which is covered by the dolomite of Changcheng System Gaoyuzhuang Formation and the Quaternary System.Through the ground high accuracy magnetic survey, magnetic anomaly data is obtained and accordingly the scope of the magnetic anomaly is blocked out.The magnetic anomaly was arranged in northeastern strike,with a length of about 4000m and an average width of about 800m.Based on the analysis of reduction to the pole as well as upward continuation and inversion on different levels,and according to the anomaly characteristics and geological data,the distribution and spatial characteristics of the hidden magnetite are determined,and the results present specific basis of physical geog-raphy for further exploration and development of the deposit. |
