摘　　要：红柱石矿床产于花岗闪长岩与上元古界震旦系地层之外接触带，该矿床属高铝泥质沉积岩在区域变质产物的基础上，再经后期接触热变质成矿，成矿后的动力变质作用及热液改造迹象比较明显。The deposit occurs at the outer contact zone between granodiorite intrussive and Upper Proterozoic strata. The protore is of high aluminium sedimentary rock on which andalusite depoeit is formed by regional metamorphism and late thermal metamorphism with evedent post ore dynamic metamorphism and hydrothermal reworks.
