摘　　要：在全国矿产资源潜力评价和中国化工矿产地质总结成果的基础上,充分考虑了重晶石矿区域成矿地质背景和成矿规律特点,系统划分了中国重晶石矿成矿区带;以空间、时间和成因为主要因素,提出了全国重晶石矿矿产预测类型划分方案。依据重晶石矿预测要素特征,归纳总结了沉积型、层控(内生)型、热液型、火山-沉积型、风化(残坡积)型等5个重晶石矿描述性预测评价模型。采用综合地质模型方法,开展了全国重晶石矿资源潜力预测,共圈定重晶石矿最小预测区659个,归并三级预测区145个,其中预测资源量大于1亿t的三级预测区有4个,预测潜在资源量14.41亿t,主要分布在1000m以浅,找矿潜力巨大。On the basis of the potential evaluation of national mineral resources and the summary results of China's chemical mineral geology,the paper gives full consideration to the geological background and metallogenic characteristics of barite ore-forming regions,and systematically divides the metallogenic zones of China's barite ore-forming regions.Based on the main factors of space,time and cause,the classification scheme of the forecast types of barite minerals in China is put forward.According to the characteristics of barite ore prediction factors,five descriptive prediction evaluation models of barite ore are summarized,including sedimentary type,stratocontrol type,hydrothermal type,volcano-sedimentary type and weathering type.By adopting the method of comprehensive geological model,the potential prediction of national barite mineral resources is made,659minimum barite prediction areas are delineated,and 145 level Ⅲ prediction areas are merged,which forecasts more than 4level Ⅲ forecast areas each with 100million tons of resources.It is predicted that the volume of potential resources is 1.441billion tons,mainly distributed in the shallow area of 1,000m,and the prospecting potential is huge.
