综合物探法在东昆仑依阡巴达铁矿勘查中应用

Integrate Geophysical Exploration in Yiqianbada Iron Ore, East Kunlun Mountains

在东昆仑祁漫塔格依阡巴达地区运用综合物探法发现多条磁铁矿体,增加了铁矿资源量,取得较好地质找矿成果。通过对M-1-1磁异常开展工作,查明高重力、高磁异常组合特征,经钻探工程验证为隐伏磁铁矿体引起。据此提出寻找矽卡岩型磁铁矿床采用以磁法为主、重力及电测深综合物探方法为辅的技术组合。

A number of iron ore body were discovered by using integrated geophysical methods,this work obtain better results of geological prospecting in East KunLun mountains Yiqianbada iron.Especially through further research on the M-1-1 magnetic anomaly, we has found out that the characteristics of high gravity and high magnetic anomaly combination is caused by the insidious magnetite.It is proved to have increased the amount of the iron ore resources effectively by geological drilling.Based on this work,we suggest that the integrategeophysical technique combination form of which it take the magnetic and use gravity and electrical survey methods as supplement should be used to prospect Skarn-type magnetite deposits.
