摘　　要：黔北务川县岩风阡铝土矿经详查工作证实,是一个以富铝、高铝硅比为其特征的大型铝土矿床,是黔北务正道地区铝土矿整装勘查的重点对象之一。文章在论述成矿地质背景和含矿岩系特征的基础上,对务正道马平期的成矿环境,包括古气候、古构造、地球化学、古地貌、沉积相环境进行了综合分析,阐明了量大质优的铝土矿床形成于大陆浅湖相沉积环境中,进而划分为黔北"大竹园式"铝土矿床。笔者建议,选好靶区,施钻试探,以期取得事半功倍的找矿新突破。By detailed exploration, Yanfengqian bauxite deposit is testified to be a big scale bauxite deposit with rich alumium and high silicon ratio. It＇ s one important target of bauxite equipped exploration in Wuzhengdao area of north Guizhou. On the basis of summarizing the geological background and ore - bearing rock, the metallogenic （paleoclimate, paleostructure, geochemistry, paleoplatform and sedimentary facies） in Maping period are studied, it introduced that the bauxite deposit formed in sedimentary environment of conti- nental shallow lake facies, then Dazhuyuan - type bauxite deposit in north Guizhou is divided. It＇ s suggested to select target area and do drilling, so that will get some new breakthrough for bauxite deposit exploration.
