2018年9月-11月新疆启鑫示范区1:5万航磁三分量测量剖面测量数据

该数据集为2018年9月-11月，中国自然资源航空物探遥感中心实测1:5万航磁三分量数据。利用中国飞龙通用航空公司运12飞机（编号B-3750），搭载AGS-863航空三分量磁力仪、AGS-863航磁三分量数据收录&补偿系统、IGI飞行姿态测量系统，HC-2000光泵磁力仪、CG-T3.0无线电测高仪、差分GPS卫星导航定位系统等设备。航磁三分量数据预处理主要操作包括数据正常场校正（采用2015年IGRF模型逐点计算正常场进行校正）、磁日变校正、滞后校正、航磁水平调整。数据集采用2000国家大地坐标系，1985国家高程，高斯-克吕格投影，中央经线93°。该数据集较为清晰的展现了启鑫示范区的磁场面貌，受白山大断裂以及疏勒河大断裂控制，航磁异常主要呈NE向和E-W向展布。利用该数据集开展了岩性构造推断，并进行了定量解释，辅助进行三维地质建模。该数据集可协议共享。

This dataset consists of 1:50000 scale airborne magnetic three-component data measured by the Airborne Geophysical and Remote Sensing Center of the Ministry of Natural Resources of China from September to November 2018. The survey was carried out using a Y-12 aircraft (registration number B-3750) operated by China Feilong General Aviation Co., Ltd., which was equipped with the following instruments: AGS-863 airborne three-component magnetometer, AGS-863 airborne magnetic three-component data acquisition & compensation system, IGI flight attitude measurement system, HC-2000 optical pump magnetometer, CG-T3.0 radio altimeter, and differential GPS satellite navigation and positioning system. The main preprocessing steps for the airborne magnetic three-component data include normal field correction (conducted by calculating the normal field point by point using the 2015 International Geomagnetic Reference Field (IGRF) model), magnetic diurnal variation correction, lag correction, and airborne magnetic horizontal adjustment. The dataset adopts the China Geodetic Coordinate System 2000 (CGCS2000), 1985 National Elevation Datum, Gauss-Krüger projection, with a central meridian of 93°. This dataset clearly depicts the magnetic field features of the Qixin Demonstration Area, which is controlled by the Baishan Major Fault and Shulehe Major Fault. The airborne magnetic anomalies are primarily distributed in NE and E-W trends. This dataset has been utilized for lithologic and structural inference, quantitative interpretation, and assisting in 3D geological modeling. This dataset is available for sharing through formal agreements.
