地面高精度磁法在辽宁板城铁矿勘查中的应用
|
摘要
辽宁板城铁矿地处我国鞍山—本溪成矿带西北部,周边鞍山式铁矿床星罗棋布,太古界鞍山群石棚子组通什村组含铁变质岩系发育,成矿地质条件优越。区内黑云变粒岩等赋矿围岩与磁铁矿的磁化率差异较大,具备高精度地面磁法测量工作的地球物理基础,通过于区内开展地面高精度磁法测量工作,圈定3条断裂构造和6处高磁异常,找矿前景良好。
Bancheng iron deposit was located in northwest of Anshan-Benxi metallogenic belt, and it developed Anshan style in iron deposits. The iron metamorphic rock system of Tongshicun formation in Archaeozoic Anshan group was developed and the metallogenic geological conditions were superior. The geophysical foundation of ground high-precision magnetic survey method was existed because of the different magnetic susceptibility between the surrounding rock and magnetite. We delineated three fault structures and six high magnetic anomalies by ground high-precision magnetic survey work in our good prospecting prospect.
