动力三角翼平台航磁测量系统及其在卡拉塔格勘查区的应用
|
摘要
航空磁法是航空物探常用的测量方法之一,具有探测深度大、效率高、成本低等优点.为满足地质填图与矿产勘查对大比例尺高精度磁测资料的需要,本次将AARC510航磁补偿和收录系统与高精度CS-VL铯光泵磁力仪搭载于动力三角翼平台上,集成了一套灵活、高效、经济、高精度的航磁测量系统.通过对卡拉塔格勘查区获得的数据的质量评价,验证了该测量系统采集、补偿数据的能力.通过对比分析勘查区航空磁测数据与地表地质和地面磁测结果,验证了利用该航磁测量系统进行区域性磁法测量的可行性和可靠性.通过解析延拓、水平梯度及斜导数等位场数据处理方法,分析了勘查区磁性构造等特征,认为勘查区发育的小规模高磁异常主要为浅源异常;区内磁性构造线主要以北西向为主,部分北东向断裂与北西向断裂切割,局部伴生的许多小规模、延伸短的构造线,推测为在构造—岩浆活动中形成的次级断裂构造或侵入岩体与围岩的接触带.
Aeromagnetic method is one of the common measurement methods of Aero Geophysical Survey, which has the advantages of high detection depth, high efficiency and low cost. To meet the need of large scale high-precision magnetic survey for geological mapping and mineral exploration, the AARC510 aeromagnetic compensation and recording system and the high-precision CS-VL cesium optical pump magnetometer are mounted on a dynamic delta wing platform, which form a flexible, efficient, economical and high-precious aeromagnetic measurement system. The ability of the measurement system to acquire and compensate the data is verified after the quality evaluation of the compensate data. After compared with the results of the geological map and ground magnetic survey results in the exploration, the feasibility and reliability of regional magnetic measurement using the aeromagnetic measurement system are verified. The characteristics of magnetic structures in exploration area are analyzed by using analytical continuation, horizontal gradient and oblique derivative processing methods. It is considered that the high magnetic anomalies with small scale developed in the exploration area are mainly shallow source anomalies; the orientation of magnetic structural lines in the area are mainly NW-trending, and some NE trending faults and NW trending faults cross cut, local structural lines with small, short extension are the secondary fault structure or contact zone between the intrusive rock mass and the surrounding rock during the tectonic-magmatic activity.
