摘　　要：贵州省铝土矿含矿岩系已经有一些研究,但从全省角度看研究有待深入。本次在贵州铝土矿整装勘查及研究成果的基础上,结合最新铝土矿成矿区带划分成果,以贵阳—清镇铝土矿田、遵义—息烽铝土矿田、凯里—黄平—瓮安—福泉铝土矿田、务川—正安—道真铝土矿田四大铝土矿集中区为背景,系统讨论贵州铝土矿含矿岩系的规律。认为贵州铝土矿含矿岩系在时空分布、赋矿地层、下伏地层、含矿岩系厚度、矿物组合和共伴生矿产以矿田为单元均表现出一定的差异性。同时,含矿岩系又表现出一定的规律性,不仅成矿机制相同或相似,而且矿物组合和共伴生矿产等亦有相似性,含矿岩系均覆于古风化壳之上。There were some studies on bauxite-bearing rock series, but their perspective in Guizhou Province, China requires further study. We discussed the characteristics and laws of bauxite-bearing rock series systematically on the basis of package exploration and research results, combining with the latest results of mineralization zone dividing as the center of Guiyang area, Wuchuan-Zhengan-Daozhen area, Zunyi area and Kaili-Huangping-Fuquan-Wengan area. We consider that there are some differences of spatiotemporal distribution, ore-bearing strata, underlying strata, the thickness of the ore-bearing series, mineral assemblage and symbiosis associated minerals between bauxite-bearing rock series from Guizhou Province and other places. However, there are also some common regularity about bauxite-bearing rock series, including metallogenic mechanism, mineral assemblage and symbiosis associated minerals, furthermore, bauxite-bearing rock series are all covered by ancient weathering crust.
