Application of EH4 Electromagnetic Image System in Finding Concealed Ore-A Case Study from Ha' erchulutu Copper-Polymetallic Deposit

Integrating the characteristics of MT and CSAMT with combination source of nature and artificial electromagnetic field,the EH4-Electromagnetic Image System is a set of double-power electromagnetic geophysical exploration system which can automatically acquire and process electromagnetic data with a lot of superiorities,such as high detecting resolution and appropriate depths of penetration(800~1200m).It is frequently used to investigate the spatial variations,sizes,the buried depth,extensions,Regularity in mineralized or alteration zones.The geophysical exploration methods was applied in a case study at Ha' erchulutu copper-polymetallic deposit,which finally turn out ideal results in finding out the concealed ores.
