高精度航空物探在幕阜山地区地质构造研究中的应用

The Application of high precision airborne geophysical research in Mufu moutian area

根据湘赣鄂交界区最新开展的高精度航空物探资料,从宏观地球物理的角度对幕阜山及邻区的地质构造及岩浆岩进行了研究。首先详细介绍了区内航空物探(包括航磁、航空伽玛能谱)的基本特征,重点分析了幕阜山特殊的航磁及伽玛能谱综合特征,并结合重力等相关资料,推断了主要的断裂构造和隐伏岩体,分析了区内的岩浆热液活动特征,进一步总结了花岗岩侵入体与主要断裂构造之间的关系,其成果能够为该地区进一步的地质研究工作提供一些参考。

Based on the new high-precision aerogeophsical data,the authors discussed the aerogeophscial feature of the geological structure and magmatic rocks in Mufu-mountain area. In this article, the aeromagnetic and gamma spectroscopy characteristic was stated. And then,authors described the special aeromagnetic and gamma characteristic of Mufu-mountain.Referenced gravity data, the authors interpret the main tectonic and concealed magmatic rocks, analyzed the magmatic hydrothermal activity characteristic, and concluded the relationship of the tectonic and intrusive rocks in aim area. The results of this article will provide some basic information for further geological research works in this area.
