摘要
滇中地区面积大约为４万平方公里，在这范围内有近百处矿床（点）。近年来，在对四种矿床类型和１２个典型矿床的研究基础上，系统总结了各种成矿的控制因素，提出了：地层，岩相古地理因素控制矿源层的同生沉积；构造和岩性控制后期金属元素活化和迁移以及工业矿床的形成；时间、空间分布是矿源层形成和后期改造成为矿床的这两种地质作用的综合体现，并且，指出了两个成矿预测区和找矿方向。
The area of Central Yunnan is about 40000 km2,nearly with 100 of ore deposits(and mineralized spots)in it.In recent years,on the basis of studying 4 ore deposit types and 12 typical ore deposits, we have summurized the controlling factors of various metallogenesis.And it is proposed that the cogenetic sedimentation of strata and lithofacies palaeogeographic factors controlling ore origin bed;structure and lithologic character controlling the activiation and removing of late metallic elements and the formation of commercial ore deposit;time and space distribution comprehensively reflect 2 geological actions,ie the formation and reformation later in becoming an ore deposit of ore origin bed.Moreover,2 metallogenetic prognosis areas and ore prospecting directions are pointed out in this paper.
