摘要

在本文中,我们在伊朗Asadabad-Hamedan附近的Chenar黑色铁矿进行了应用地磁反演研究。本研究的主要目的是详细描绘和可视化Chenar黑色铁矿的矿石块体,并找到地质钻探岩心的合适位置。在这项研究中,使用加拿大制造的2019年GEM- GSM19T磁力计在10天的数据采集期内获得了4300个地磁读数。通过对契纳尔铁矿地磁资料的分析,成功地确定了研究区内的易受影响的区域,并提出了矿区内6个钻孔点的位置,以供进一步调查和验证地球物理资料。我们的结果描绘了四个伸展成脉状的地块。根据磁晕的大小,我们的地球物理结果估计研究区东部三个地块的矿床约为250万吨,西部第四个地块的矿床约为25万吨。

Geomagnetic inversion for delineation of ore deposits in chenar mine
In this manuscript, we have performed an applied geomagnetic inversion study in the Chenar ferrous mine near Asadabad-Hamedan of Iran. The principal purpose of this study was to depict and visualize the ore massif of the Chenar ferrous mine in details and to find the suitable locations for geological drilling cores. In this study, 4300 Geomagnetic readings were acquired over a ten-day data acquisition period with a Canadian-built 2019 GEM- GSM19T magnetometer. The analyzes of the geomagnetic data in the Chenar ferrous mine successfully identified the susceptible zones in the area of study, and we have suggested the location of six drilling points in the mining area for further investigation and verifying of geophysical data. Our results depict four massifs which are extended as veins. According to the dimensions of the magnetic halos, our geophysical result estimates the ore deposit to be about two and a half million tons for three of the massifs in the Eastern part and 250 thousand tons for the fourth massif in the Western part of the study region.
