摘要
The Jintan gold deposit, located in the Kanggurtag gold ore belt of Eastern Tianshan, Xinjiang, is a ductile shear belt type gold deposit. The orebodies commonly occur as slabs controlled by ductile shear belts. The EH4 electromagnetic depth sounding technology was carried out to integrate the geophysical investigation of this gold deposit, the results of measurement can clearly distinguish mylonitized zone from wall rock: 1) mylonite zone with the characteristics of low resistivity (<300 Ω · m); and 2) wall rock with the characteristics of medium-high resistivity (≥300 Ω · m). The interpretation of the measured profiles show good prospecting potential in the east and west of the mineral district, which point out the direction in searching successive resources of the crisis mine.
