| 摘 要： | 可可塔勒铅锌矿床受火山喷发中心和沉积洼地控制，铅锌沉淀于海进阶段的局限还原卤水池中；矿下存在大型蚀变带，构成成矿流体对流循环过程中的水-岩作用带；后期造山挤压过程使地层和矿体倒转，矿床最终定位于麦兹倒转向斜之北东倒转翼的东南近转折部位。指出该矿床属海底火山喷流沉积改造型块状硫化物铅锌矿床。

| Abstract: | The Keketale Pb-Zn deposit may be controlled by the volcanic effusive center and sedimentary depression. Pb and Zn deposition were restricted in the locally reducing haloid pool during the transgression phase. There was a large-scale alteration belt under the ore body. The water-rock reaction belt was formed in the convection-circulation process of the mineralizing fluid; The strata and ore-body were overturned in the later period orogenic extrasion process,It is finally orientated near the east-southern transition part in the novth eastern overturned limb of the Maizi overturned syncline. This deposit belongs to the massive sulfide Pb-Zn deposit of the sea floor-exhalation sedimentation-reformation type. |
