| [摘要]勐野井钾盐矿产于新生代环扬子地块西缘兰坪-思茅双向弧后-前陆盆地勐野井组棕红色、杂色盐溶泥砾岩建造中。成矿具有明显的蒸发沉积韵律,钾盐矿层的产出受地层、岩相、构造等因素的控制。将其厘定为新生代(湖相)沉积型钾盐矿的典型矿床-勐野井式钾盐矿。并将成矿条件与之类似的兰坪-云龙、镇源-景谷、江城-勐腊3个地区作为预测工作区,以MRAS 定位定量方法,基于GIS 的矿产资源评价系统进行矿产预测,优选最小预测靶区20个,估算钾盐矿石资源量38000万吨,作为今后寻找与勘查该类型矿床的依据。 |

| Abstract:The Mengyejing potash deposit lies in brown and variedness salting-in nagelfluh formation of the Cenozoic Mengyejing rock assemblage which is located at the back-foreland basin of the Lanping-Simao bidirectional arc zone, west of the Yangtze massif. Its metallogenesis exhibits evident evaporation-sedimentation cyclothem. The output of potash beds is controlled by strata, lithofacies and tectonics directly. We define it as a typical Cenozoic (lake facies) potash deposit, the Mengyejing-type potash deposit. We take Lanping-Yunlong, Zhenyuan-Jinggu and Jiangcheng-Mengla as three work areas for orediction, which have similar metallogenesis conditions with the Mengyejing potash deposit. We carried out the mineral resources prediction based on the MRAS location and quantitative method and GIS mineral resources evaluation system. We determined 20 preferred smallest prediction targets, with estimated potash resources of 0.38 milliard tons, which can be considered as the basis for prospecting and exploration of deposits of this type in the future.rces prediction based on the MRAS location and quantitative method and GIS mineral resources evaluation system.
