摘　　要：黔北栗园向斜北段铝土矿是产于早志留世韩家店群(S1Hj)泥页岩或晚石炭世黄龙组(C2h)粗晶灰岩之上的一水硬铝石型沉积型铝土矿床。铝土矿产出层位为晚石炭世大竹园组(C2d)。在阐述该铝土矿床的成矿地质背景和矿床地质特征的基础上,对矿床形成过程中的控矿条件进行了分析,认为主要有构造、古地理及古气候、地层、成矿物质来源四大控矿条件。鉴于区域内具备相似条件的向斜构造还有多个,如参照该矿床开展地质勘查工作,有望再找到多个中—大型铝土矿床。The bauxite deposit in northern block of Liyuan syncline of northern Guizhou was a kind of diasporic and sedimentary bauxite occurred in mud shale of Hanjiadian Group in early Silurian Epoch（ S1Hj） or coarse grained limestone of Huanglong Formation in late Carboniferous Epoch（ C2h）. The production horizon for the bauxite was Dazhuyuan Formation in late Carboniferous Epoch. Based on the descriptions of metallogenic geological settings and deposit geological properties,the authors analyzed the ore control conditions in the process of its formation： tectonics,palaeogeography and palaeoclimate,stratigraphy,ore-forming material source. In light of other syncline structures of similar conditions existed in the study area,the authors suggested to conduct further exploration for a next medium to large sized bauxite deposit.
