| 摘 要： | 新疆金滩金矿床位处东天山康古尔塔格金矿带,是典型的韧性剪切带型金矿床。矿山资源储量严重不足,急需寻找接替资源。根据金滩金矿床严格受韧性剪切断裂控制的特点,利用EH4电磁测深技术对其进行地球物理勘探,测量剖面清晰地区分了糜棱岩带和围岩:①糜棱岩带具有低电阻率特征(<300Ω·m);②围岩具有中高电阻率特征(≥300Ω·m)。测量剖面的解译结果显示了矿区东部和西部均具有良好的找矿潜力,为矿山下一步找矿指明了方向。

| Abstract: | 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); (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. |
