摘要
磁测方法在寻找金矿的工作中,从区域普查,到详查勘探的各个阶段,均能较好地发挥作用。本文通过在胶东金矿带上的几个实例,表明应用磁测可以查明与金矿赋存有关的断裂构造、破碎蚀变带,圈定不同岩性的接触带以及侵入体的分布范围等,再结合其它物探化探方法,配合地质填图,就能达到寻找金矿的目的。
Abstract
Magnetic survey can play a quite satisfactory role in the search for gold deposits at various stages from regional reconnaissance to detailed exploration. With some examples on the eastern. Shandong gold ore belt, this paper demon strates that magnetic survey can be employed to detect gold-related fault structures and fractural alteration zones, and delineate contact zones of different rocks as well as distribution limits of intrusive bodies. Combined with other geophysical-geochemical prospecting methods and in coordination with geolo gical mapping, it can attain the aim of finding gold deposits.
