航磁、航空TEM数据精细化处理手段在黑龙江嘎来奥伊地区矽卡岩型铅锌矿的应用研究
|
摘要
对航磁和航空TEM数据精细化处理手段——磁化强度矢量反演和Maxwell板状体反演进行了简单介绍,并以黑龙江嘎来奥伊地区矽卡岩型铅锌矿为例,阐述了两种处理手段在该地区实测数据的处理结果,总结出一套数据处理、分析及解释的思路,即磁化强度矢量反演加视电阻率剖面能够分析成矿环境,分析提取矿致异常,继而采用Maxwell对异常地段进行板状体反演,模拟矿体(低阻体)在地下的分布位置,从而指导钻孔布设,在已知矿区的试验效果较好。
This paper introduces the refineddata processing of magnetization vector inversion and Maxwell plate inversion,and takes the skarn type lead-zinc mine in Galaiaoyi area of Heilongjiang province as an example,summed up a set of data processing,analysis and interpretation of the idea that the magnetization vector inversion with the apparent resistivity profile can analyze the metallogenic environment,analysis and extraction of ore caused by abnormal,and then use Maxwell has a plate-like inversion of the abnormal lot to simulate the distribution of the orebody( low-resistance) in the ground,thus guiding the drilling and laying,and the test results in the known mining area are better.
