摘要:
河南省渑池县段村-雷沟铝土矿特征类似于同矿带其他矿区铝土矿特征,但也有区别。本文通过对该矿床岩性特征、矿体形态及矿石化学成分的对比分析,认为其总体成因符合袁跃清关于豫西铝土矿的三阶段成因。在微环境上,段村-雷沟铝土矿形成于开阔的岩溶盆地之中,盆地内有起伏,含溶盆和溶洼。在后期富集过程中,其富集程度远远高出周边其他铝土矿区。

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 .
