摘要
滇东南地区是云南省重要铝土矿成矿区,铝土矿床区含铝岩系主要为上二叠统吴家坪组(龙潭组)和第四系,矿床类型为原生沉积型和堆积型两类。铝土矿矿床(点)主要集中分布于屏马古陆与丘北—富宁一线区域内,该线以北东南盘江区偶见铝土矿矿床(点),且吴家坪组多发育硅质岩。滇东南不同地区矿床成因、地质特征、控矿因素均具有一定差异性。
The southeastern region of Yunnan province is an important metallogetic area of bauxite,in which the aluminum-containing rocks mainly is Wujiaping Formation(Longtan Formation) of upper Permian group and Quaternary,the two kinds of ore deposit type are primary sedimentary and accumulation.Bauxite deposits(dots) are mainly distributed in the Pingma ancient land to Qiubei-Funing line area,the line north of the Nanpanjiang occasionally bauxite deposits(dots),and the group of more developed Wujiaping chert.There are differences of deposit genesis,geological characteristics and ore-controlling factors in the different area of the southeast Yunnan.
