| 摘 要： | 马海钾矿床是柴达木盆地内重要的盐类矿床之一。从盐类矿床沉积物的物相分析入手,着重揭示该成盐盆地沉积环境和古地理变迁特征,论述湖盆由形成、发展至老化衰亡的演变规律,反映了从上新世末期以来新构造运动在矿区地质构造上的典型表现,由这些成矿因素构建的矿床地质构造特征也得到总结。依照持续稳定发展的要求,就矿床开发过程中出现的急功近利局面,提出调整产品结构和重新布局开采对象的新策略,对企业生产实践具有指导意义。

| Abstract: | Mahai salt lake is located in the northwest margin of Qaidam basin.In the paper,the authors tried to reveal the sedimentary environment and paleogeographic evolution of Maihai basin though the phase analysis of saline sediments.Evolution rules of the lake basin for formation,development and disappearance are discussed,which reflects the typical neotectonics of the mining area since the Pliocene.Geological characteristics constructed by these ore-forming factors are also summarized.In order to solve the prob... |
