新疆哈密沙泉子地区断裂构造航空重磁遥特征及相关性分析

CHARACTERISTICS OF AERO GRAVITY AND MAGNETISM REMOTE SENSING AND CORRELATION ANALYSIS OF FAULT STRUCTURES IN HAMI SHAQUANZI AREA,XINJIANG

为了研究航空物探(重、磁)及遥感在断裂构造研究中的关系,利用新疆哈密沙泉子地区开展的航空物探(重、磁)遥感调查数据,开展了该区断裂构造划分,共划分断裂构造18条。对划分的18条断裂进行了重磁遥特征及相关性分析,结果显示,区内所划分的一、二级断裂均为重磁遥相关,重磁遥相关的三级断裂也是与主体构造格架方向一致的断裂;重磁、磁遥相关断裂均为三级断裂,不相关断裂也是三级断裂。总体上,利用重磁遥资料进行大断裂或主体格架断裂划分时关联性更好。

In order to study the correlation between aero geophysical survey(gravity and magnetism)and remote sensing in the study of fault structures,18 fault structures were identified using the aero geophysical survey(gravity and magnetism)remote sensing data in Hami Shaquanzi area,Xinjiang.Based on the analysis of the characteristics and correlation of the 18 faults,the results show that the firstorder and second-order faults in the area are all gravity magnetism remote sensing related.The third-order faults related to gravity magnetism are also faults in the same direction as the main structural framework.Both gravity and magnetism related and magnetism remote sensing related faults are the thirdorder faults.The unrelated faults are also the third-order faults.On the whole,it is more effective to identify large faults or main frame faults using gravity and magnetism remote sensing data.
