摘要
遵义铝土矿主要分布在乌江两岸,成矿远景区面积3000余km2,包括了后槽、仙人岩等大、中、小型矿床(点)共32处。均为铝土矿底板的粘土页岩经风化后原地堆积或近距离搬运后的产物。其沉积或堆积作用,与基底的古岩溶溶蚀坑、(洼)密切相关,并使铝土矿沉积在平面上或纵向上都具有一定的分带性。其矿床成因类型属于古风化壳型岩溶坑(洼)沉积铝土矿床。根据成矿地质特征分别建立了高铁铝土矿和低铁铝土矿的成矿模式。
The Zunyi bauxite mainly distributes in both banks of the Wujiang River, and the ore Prospecing area is about 3000 km^2, including Houcao, Xianrenyan and other 32 large, medium and small scale deposits. They are all the products of in - place accumulation and short distance migration of bauxite floor＇s clay shale after weathering. The sedimentation or accumulation has a close relationship to fossil karst pocket and depression of basement, and （ bring/made the deposition of bauxite mine having definite zonation horizontally or longitudinally. The genetic type of ore deposit was attributed to ancient crust of weathering karst depression bauxite ore deposit, the metallogenetic patterns are established separately, including high ferrous bauxite and low ferrous bauxite in the light of the geological characteristic of mineralization.
