云南腾冲—云县地区航磁特征及其在地质找矿上的应用
|
摘要
为补充完善滇西地区基础地球物理资料,在云南腾冲—云县地区实施了1:5万高精度航磁调查,依据最新的1:5万航磁测量数据,于2015—2017年间我们先后三次在该区开展了区域性野外岩矿石磁化率测量及部分航磁异常查证工作.结合地质、矿产、化探、区域重力、岩(矿)石磁化率以及剩磁资料,在分析研究该区航磁异常特征及地质成矿条件的基础上,圈定了14片找矿远景区,为该区矿产资源调查评价提供了高质量航磁资料及解释成果,为该区地面矿产勘查工作科学部署和合理规划提供了线索及依据,并通过实例探讨了该区航磁资料在地质找矿上的应用.我们推测昌宁县无量山群变质岩中有找到大-中型铁矿床的潜力,另外对核桃坪多金属矿外围航磁异常点进行了地、物、化综合查证,结果表明其具有较好的找矿远景.云南腾冲—云县地区航磁综合研究结果为该区勘查找矿、地质构造研究、地质灾害预防等工作提供了重要支撑.
In order to better complete the comprehensive aeromagnetic research work in Tengchong-Yunxian area of Yunnan province, we conducted the field field rock magnetic susceptibility measurement and partial aeromagnetic anomaly verification three times in 2015-2017. According to the latest 1: 50000 aeromagnetic survey data, combined with geological and mineral resources,magnetic susceptibility, remanent magnetism, regional gravity and geochemical data, we analyzed the characteristics of various rock magnetic susceptibility and the characteristics of aeromagnetic anomalies in the study area are. The delineation of the 14 ore prospecting areas, provide clues and basis for ground work of mineral exploration deployment. And we discussesed the application of aeromagnetic in geological prospecting by example. We speculate that there is a potential for finding large-medium iron deposits in the metamorphic rocks of the Wuliangshan Formation in Changning County. In addition to the Hetaoping polymetallic deposit periphery of aeromagnetic anomaly points, comprehensive verification is carried out, The magnetic-method quantitative results inversion show that it has good ore prospects. The results of the study provide important support for the interpretation of aeromagnetic data, geological prospecting, tectonic evolution and so on.
