综合电法在新疆哈西金矿区寻找隐伏矿的应用

EH4电磁测深和高密度电法测量均为近年来发展起来的地球物理手段.EH4电磁测深是基于电磁原理的地球物理手段,探测深度大(可达1000m),可用于确定矿化系统深部的宏观构造格架和产状变化;高密度电法集电剖面和电测深于一体,对地质结构解析度高,且同时能够进行激发极化法测量,探明地下金属硫化物富集情况.这两种方法在新疆哈西金矿区综合运用,在寻找覆盖层下的隐伏矿方面取得了良好的效果.

APPLICATION OF INTEGRATED GEOPHYSICAL EXPLORATION TO FIND CONCEALED ORES IN THE HAXI GOLD MINING AREA

Two geophysical exploration methods like EH4 electrical conductivity survey and high density resistivity method(HDRT) have being developed in recent years.Having deep penetration,EH4,an electromagnetic exploration method,can determine variations of macrostructure and occurrence of mineralization system in the deep.Obtaining both electrical sounding and resistivity profile simultaneously,HDRT can give geological structures with high detecting resolution,perform in meantime survey of induced polarization,and detect enrichment situation of metallic sulphide clearly.These two methods,conducted synthetically in Haxi gold mining area,turned out expected and ideal results in exploration of concealed ores under the overburden.
