强干扰背景条件下TEM探测铁矿资料解释方法研究

DATA EXPLANATION OF TEM TO EXPLORE IRON DEPOSIT IN STRONG JAMMING BACKGROUND

文章从采集数据拟和入手,将滤波、时深转换后的反演数据绘制有关图件。通过分析全区视电阻率单支曲线,得出测区内的电性异常区,有铁矿存在时的地层电性特征曲线为KH、HA型,无铁矿存在时的地层电性特征曲线为H型;通过视电阻率拟断面图分析磁铁矿异常体赋存和断层的特征;利用视电阻率切片图来推演矿体展布形态。

A method of data fitting was studied in the paper, and relevant graphs were drawn with filtered and time - depth transferred data. Electronic property anomaly was got from analyzing single curve. If there, exists an iron mine, KH or HA type electronic property carves of strata were presented, and H type curve was got when there is no iron mine. Based on study of apparent resistivity section map, distribution of magnetite anomaly and characteristic of fault could be got. Ore distributed shape was deduced by the apparent resistivity section.
