综合物化探技术在中-南祁连山察汗诺北部航磁异常检查中的应用

摘要

文章以青海中-南祁连山察汗诺北部的青C-2012-280和青C-2012-281号航磁异常检查为例,在综合前人地质、物化探和矿产资料的基础上,采用地质剖面测量、高精度磁法剖面测量、岩石磁参数测量和岩石地化剖面测量方法进行航磁异常地面检查.分析磁异常形成的地质原因,对航磁异常做出定性判断,对异常的成矿潜力进行评价,对下一步的工作提出了建议.综合物化探方法在青海省中-南祁连山的航磁异常检查和找矿工作中取得了良好的效果.%Taking aeromagnetic anomaly Qing C-2012-280and Qing C-2012-281 as an example this paper integrated results of geological section survey,high precision magnetic profile survey,rock magnetic parameter measurement and petro-geochemical profile survey to check ground magnetic anomlies on basis of previous geological,geophysical,geochemical and mineral resources data.Then geological cause of the anomly is analyzed,quantitative estimation made and the ore potential evaluated and suggestions for furthe prospecting proposed.The integrated geophysical and geochemical exploration technology have achieved good results in check ground magnetic anomlies and ore prospecting incentral and southern Qilianshan mountain area in Qinghai province.
