摘　　要：著名的贵州“修文式”铝土矿是黔中铝土矿的重要类型。该类型铝土矿形成于早石炭世维宪中晚期,含铝岩系为石炭系下统九架炉组(C_(1)jj)。“修文式”铝土矿包含猫场、小山坝、小院、长冲河等典型矿床,累计查明铝土矿资源/储量4.28亿吨。燕垅铝土矿床呈近南北向弓形带状连续展布,南北长约13.5 km,东西宽0.5~1 km,含矿岩系及其顶底板近直立状产出,可清晰观察到矿体、矿系及其与顶底板的不整合接触关系,地质现象十分丰富,被选为中国地质学会第十七届矿床会议野外考察路线之一。The famous“Xiuwen-type”bauxite in Guizhou is an important type of bauxite in central Guizhou.This type of bauxite was formed in the middle and late Visean stage of the Early Carboniferous.The aluminum-bearing rock series is the Jiujialu Formation(C_(1)jj)of the Lower Carboniferous.The“Xiuwen-type”bauxite contains typical deposits such as Maochang,Xiaoshanba,Xiaoyuan,and Changchonghe.The accumulated verified bauxite resources/reserves are 428 million tons.The Yanlong bauxite deposit is continuously distributed in a nearly north-south arcuate band.It is about 13.5 kilometers long from north to south and 0.5 to 1 kilometer wide from east to west.The ore-bearing rock series and its roof and floor are produced in a nearly vertical state.The ore body,ore system and its unconformable contact relationship with the roof and floor can be clearly observed.The geological phenomena are very rich and it has been selected as one of the field inspection routes for the 17th Mineral Deposits Conference of the Geological Society of China.
