地面高精度磁测在八河铁矿区找矿中的应用

The Application of Groud Superprecision Magnetic Survey in Prospecting in BaHe Iron Mining Area

磁法勘探作为发展最早应用最广的一种地球物理勘探方法之一，它在寻找矿产资源，尤其是在磁性较强的矿产方面更能显示出独到的优越性．本文就金寨县青山镇八河村子矿区的磁法勘探应用效果进行研究，结合地质资料对磁异常进行定性解释，以及通过定量计算得出其埋深和宽度．结果表明：该矿区有一处受构造控制的斜磁化有限延伸板状磁铁矿化体，其走向大致为北东向45。角，埋深为2～3m，板状体宽度为3～4m．

The magnetic prospecting as one of the earliest and broadest geophysical prospecting methods, can demonstrate the original superiority in seeking the mineral resource particularly in stronger magnetic minerals. This article conducts the research on magnetic prospecting application effect mining area, Qinshan Town of Jinzhai County. It carries on the qualitative interpretation to the magnetic prospecting application effect magnetism to infer the magnet to mineralize the body approximately, and obtain its burying depth and the width through the quantitative evaluation. The result indicated that this mining area has a limitedly extended and structure controlled plate - type magnet mineralization body. It moves towards the north east , and the angle is bigger than 45°, burying depth 2 -3 m, the tabular body width is 3 -4 m.
