云南省勐野井式钾盐矿找矿模型及预测
The Prospecting Model and Prediction of the Mengyejing-Type Potash Deposits in Yunnan Province
摘要
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.关键词
