云南保山核桃坪铅锌矿外围航磁异常找矿进展
|
摘要
为了对云南腾冲—云县地区1∶5万高精度航磁调查项目中所选编的部分核桃坪外围航磁异常进行异常查证,在异常点进行了地质、物探、化探剖面测量工作,并通过2.5D人机交互反演,对成矿潜力做了定量分析,结果表明核桃坪铅锌矿外围有较好的铁、铜、铅、锌多金属矿找矿前景,为在该区域进一步开展找矿工作提供了依据。同时本研究也证明了通过航空物探进行快速扫面后进行异常筛选,然后通过地面物探、化探、地质等综合查证手段进行定位、区分、评价有意义异常,是一种在勘查区可行、经济、快速、高效的空—地联合勘查方法。
This study belongs to the aeromagnetic anomaly verification part of the 1 ∶ 50,000 high precision aeromagnetic survey project in Tengchong-Yunxian area,Yunnan Province. In order to verify some selected aeromagnetic anomalies in the periphery of the Hetaoping Pb-Zn deposit,the authors carried out geological,geophysical and geochemical survey at the abnormal points. The 2.5 D human-computer interaction inversion was used to quantitatively analyze the mineralization potential. The prospecting potential of Fe-Cu-PbZn-polymetallic ore in the periphery of Hetaoping Pb-Zn deposit is proved to be huge,which provides the basis for further prospecting.At the same time,it is proved that after the rapid scanning using aerial geophysical prospecting,researchers should carry out high precision ground geophysical,geochemical and geological techniques and other comprehensive verification methods for positioning,distinguishing and evaluating meaningful anomalies,which could be an economical,fast and efficient air-ground combinational survey method.
