Application of the Transient Electromagnetic( TEM) Technology to the Ayituohan Copper Deposit,Habahe County,Xinjiang

The Ayituohan copper deposit in Habahe county of Xinjiang is located in the southern margin of the Altai orogenic belt. This deposit is adjacent to the famous Ashele large copper-polymetallic mine,but they have significantly different metallogenic types. This study deployed eight survey lines in the deposit for large loop transient electromagnetic( TEM) data collection and processing,and made comparison between the inversed electromagnetic anomalies and prospecting line profiles to delineate deep orebodies. Drilling verification of the anomalies along the prospecting line No. 5 indicates that the delineated low-resistivity anomalies correspond well to the locations of real orebodies in the sub-surface. The spatial distribution of electric resistivity inferred from TEM can aid to better understand the further extension of mineralized orebodies,and may provide evidence for evaluation of resource potential in this mine area.
