摘要

阐述了罗维矿区航磁、地面高精度磁测以及EH4大地电磁测深法的观测成果及圈出的异常,对勘查工作中遇到的地质问题及矿产特征作出了推断与预测,其结果指向几乎是一致的。这些物探成果在近年的勘查找矿工作中得到钻孔工程验证,在圈定的磁异常内探测到多层含磁黄铁矿的闪锌矿和钨铋矿体,显示出较好的深部找矿指示作用,与以往航磁测量推断本区存在磁性隐伏岩体的结论相吻合。同时,依据物探成果推测矿区成矿机理和成矿模式,对找矿方向与找矿潜力进行了分析探讨。

Abstract

The aeromagnetic information at the Luowei mine,the ground high-precision magnetic survey,observed results using EH4 magnetotelluric sounding method as well as abnormal site were addressed in this article.Moreover,we made the inference and prediction for geological issues together with mineral characteristics,and all the results nearly exhibited the same direction.The results of geophysical exploration in recent exploration prospecting works won the validation of drilling engineering,and the bismuth and tungsten orebodies with pyrrhotite sphalerite were revealed at the tagged magnetic anomaly sites,suggesting its well indication for deep prospecting. In addition,our conclusions were same with the results about magnetic concealed rock mass and its depth applying aeromagnetic survey 30 years ago.Finally,according to ore-forming mechanism and metallogenetic model based on geophysical exploration results,the prospecting direction and prospecting potential were discussed.
