摘要
第四系堆积型铝土矿,含矿岩系主要分布于寒武系中、上统娄山关群(∈2—3ls),灰、微红色中厚层状细晶白云岩为基底的岩溶洼地、坡地及岩溶谷地的第四系红土层中。铝土矿含矿岩系厚度受基底古侵蚀面形态的影响,一般凹下地段厚度大,凸起地段厚度变小甚至尖灭。
Quaternary accumulation type bauxite,ore bearing rock series are mainly distributed in the middle and Upper Cambrian Loushan Guan Qun(∈2—3ls),ash,micro red thick bedded fine crystalline dolostone in the basement of the karst depression and slope and karst valley of the Quaternary red clay layer.The thickness of the ore bearing rock series is affected by the shape of the ancient erosion surface of the substrate,the thickness of the section is large,and the thickness of the raised section is small and even pointed out.
