Abstract
Maixi Bauxite Mine is located in the Xiuwen-Qingzhen mining area within the Yangtze block in central Guizhou.The folds and fault structures are developed in the mining area,and the bauxite deposits occur in the aluminum-bearing rock series of the Jiujialu formation in the Lower Carboniferous,rich in resources and reserves in the mining areas.This article systematically studies the sources of ore-forming compentents,geological characteristics,and genesis of ore deposits in the mining areas by the methods such as petrology,mineralogy,and geochemistry.The results indicate that the ore-forming compentents in the mining areas may come from the underlying carbonate rocks of the Loushanguan formation of the Cambrian,and have undergone a multi-stage and complex mineralization process:"Weathering leads to initial enrichment--Colloidal action leads to the polymerization---Desilication leads to enrichment--The transformation effect of weathering and leaching leads to mineralization".This study is based on the diversified exploration indicators of"ore outcrop--ore bearing strata--structure",and it is speculated that the eastern and northern periphery of the mining area can be the next exploration prospect.关键词
