Abstract:

Tuokesai lead-zinc deposit is located in Sailimu block, Yili-Yisaike lake microplate. The ore body hosted in Lower Proterozoic Wenquan group carbonate rock. The ore bearing bed extends steadily and the ore body occurs along the strata with bedded, presented banding and lamellar feature. Leadzinc ore mineral association is simple. On the basis of analysis the genetic type belongs to sedimento-metamorphic deposit which is hosted in carbonate rock. Mining area is located in 1∶200,000 stream sediment survey, metallometry and placer abnormal area. Pb-Zn-Ag composite anomalies are delineated in this area. Pb and Zn as main mineralizing elements have anomalies of large area, high strength, good superposition; and earth's surface lead-zinc mineralization body correspond to these anomalies well. IP scanning mid-low resistance and high polarizability reflect earth's surface and shallow leadzinc mineralization body. Transient electromagnetic measurements for high susceptibility abnormalies reflect deep oreshoot. Based on comprehensive analysis of ore-forming geological conditions, geochemistry and geophysical abnormalies, we establish geological-geochemistry-geophysical prospecting model preliminarily.
