摘要
云南堆积型铝土矿典型矿床称为卖酒坪式,成矿物质来源于吴家坪组或龙潭组原生沉积铝土矿/岩层。矿床分布于与矿源层邻近的下伏中、上泥盆统—下二叠统中发育的溶丘漏斗、溶蚀坡地、石牙坡地和峰丛谷地等4种岩溶地貌类型中。岩溶地貌对堆积体厚度及形态起控制作用,各堆积类型Al2O3、A/S和含矿率均有一定规律。
The typical ore deposit of accumulate bauxite deposit is called Maijiuping accumulate bauxite de- posit. The metallogenetic material of it originates from the original sedimentary bauxite/rock bed. The ore deposit is in the 4 main karst geomorphological types of karst funnel, karst slope, stone teeth slope and peak cluster valley of underlying Upper Palaeozoic Middle, Upper Devonian--Lower Permian horizon near the ore source bed. The karst geomorphology controls the thickness and form of accumulate ore body. The AL2O3 , A/S and ore content of various accumulate types have a certain rule.
