| 摘 要： | 辣菜水锌矿床产于海西-印支期盆地边缘,矿体严格受石炭系下统石磴子组下亚段白云岩控制,呈层-似层状,具层控型特征。矿床成矿具有多期性,早期沉积为矿胚层,受断裂构造热动力改造成矿体,后期岩浆热液叠加,矿体进一步富集,形成富闪锌矿体。通过成矿环境及矿床特征研究分析,认为该矿床成因属于沉积-改造-叠加的复控型矿床。

| Abstract: | The Lacaishui zinc deposit in Qingxin county is on the edge of Hercynian-Indochina basins.The ore body is strictly controlled by sub-group of Carboniferous rock and the sub-section of Ishidan dolomite,and is layered or like layered？and strata bound.The mineralization is multistage.In the early deposition it is protore and then converts into ore body which is affected by faults in thermal power.Finally secondary ore body is enriched to form rich sphalerites through postmagmatic hydrothermal superimposition.According to the study on the ore-forming conditions and deposit characteristics,the Lacaishui zinc deposit is sedimentary-transformation-complex overlay control type deposit. |
