Abstract: Sareke glutenite type copper deposit in the Western Tarim Basin is located in the triangle area of Taras-Fergana north-west dextral strike-slip fault zone, Sawayalton-Jigen sinistral strike-slip thrust fault zone, and the front faces zone of Pamir thrust fault. A large number of Mesozonic-Genozoic glutenite type copper-lead-zinc deposit are distributed around Sulutielieke rising belt, showing the rise belt plays an important role in controlling glutenite type copper-lead-zinc deposit. Geochemical characteristics of trace elements and rare-earth elements in the main stratum of Sareke mine show that the source of ore-forming material is mainly from the denudation of the basement uplift and is the continental depositional environment. The ore-hosting stata Kuzigongsu group conglomerate REE overall loss, show the presence of strong reduction of basin fluid and the deposit in reduction of basin fluid under transformation superimposed enrichment. Audio magnetotelluric inversion recovery basement morphology characteristics show that bonanza and the slope zone between the northwest direction concealed basement rise and secondary deprsssions of both sides of the rise has a close spatial relationship. The tectonic lithofaces control with syngenetic tetonic belt and interlayer fracture with conductive to reducing migration of basin fluid accumulation and precipitation of metal elements in favorable facies zone and geochemical interface traps, mark of tectonic lithofacies for the deep ore-body prospecting prediction.
