| 摘 要： | 青海东昆仑肯德可克铁钴多金属矿床位于柴达木盆地西南缘,祁漫塔格弧后裂陷带中部.矿体产于上奥陶统热水喷流沉积的炭泥钙铁硅质岩建造中,地层与构造控矿作用明显.印支-燕山期脉岩比较发育,近矿围岩蚀变组合复杂、分带不明显,说明有多期热液活动参与了成矿.因此,肯德可克铁钴多金属矿床属热水喷流沉积(改造)型矿床,形成铅锌-钴铋金-铁成矿系列.

| Abstract: | Kendekeke Fe - Co multi - metal deposit in Qinghal is located in the southwest edge of Qaidam basin and middle parts of Qimantage rear arc rift zone. Orebodies are distributed in the upper Ordovician carbonaceous mud calc- iron - silicate formation of hydrothermal spout sediments, and obviously controlled by strata and structures. Indo - Sinian and Yanshanian dykes are developed. Wallrock alteration assemblages near orebodies are complex and wallrock alteration zonation is not obvious, presenting involving of mutil - hydrothermal fluids in mineralization. It is concluded that Kendekeke Fe - Co multi - metal deposit is belong to hydrothermal spout sediment/transformation type, and constitutes Pb- Zn, Co- Bi -Au, and Fe mineralizing series. |
