磁法勘探大别山区探矿中的应用

Application of Magnetic Exploration to the Prospecting in DaBie Shan Area

本论文介绍了安徽省大别山区铁矿磁异常数据的处理及解释。论文首先对网格化的野外原始磁异常数据进行滤波处理,以消除测量的偶然误差和近地表不均匀磁性体的干扰。然后,对上述预处理后的磁异常数据进行解析延拓,本论文作了三个不同高度的向上延拓及两个不同高度的向下延拓。通过上述数据处理,结果表明,利用这种滤波和解析延拓方法对确定地下异常体与预测成矿区是很有成效的。

This disquisition is introduce about magnetism abnormity date of copper and iron ores in a mountainous area of dabie in Anhui province. Firstly, for the sake of dispelling errors by chance, and asymmetric magnetic body disturbance near to ground. Afterward, the magnetic anomalous data by above preprocessing, is transacted in resolution continuation method, including four upward and downward layers. Transit above transaction indicate that, the method of filter and resolution continuation can effectively confirm subsurface anomalous body and forecast future mines.
