摘要
库米什盆地是新生代断陷盆地,处于干燥大陆气候控制区,湖水一直处在蒸发浓缩状态,在上更新统后期(约35kaBP)开始有石盐矿生成,全新统后期(4.5ka BP)地壳稳定,气候持续干旱,形成厚大的石盐主矿体,并且逐步进入干盐湖阶段,晶间卤水进一步浓缩,形成液相KNO3矿,在其上形成了富钾石盐壳。
The Kumishi Basin, a Cenozoic block-falling basin, has been controlled by a dry continental climate and continuously underwent a concentration process due to evaporation. The rock salt began to form in the late Pliocene to Pleistocene （35 ka BP）. The thick rock salt bodies assembled in the late Holocene （4.Ska BP） because of the stable crust and the continuous dry climate. With the evolution into the dry salt lake stage, the brines occurring in the crystals further concentrated and the liquid-phase KNO3 formed, which is overlain by Krich rock salt.
