Abstract
The geological characteristics of bauxite in Duancun -Leigou of He'nan,are similar to other mines in the same minerialization ,but there are some differences .By the comparative analysis of lithology,morphology and chemical composition of ore ,this article considers the causes obey the three stages of bauxite genesis in the western of He'nan Province ,which proposed by Yuan Yueqing . Analysis on the micro-environment ,Duancun-Leigou bauxite are formed in an open karst basins , undulating topography ,with small karst basins and swamps .The level of enrichment process at the later stage ,is higher than other neighboring bauxite .关键词
