| Abstract:The Tianshenqiao sedimentary bauxite is a medium-size bauxite, and is the best quality bauxite deposit with largest usable resource quantity ever discovered in Wenshan area. The ore body lies on the west limb of Tangzibian syncline and occurs in Permian Longtan Formation. The main minerals in the ore include diaspore, boehmite, anatase, pyrite, hematite, kaolin and mica, and the ores are mainly of pellet and psammitic textures. Based on an analysis of the ore-forming geological characteristics of Gantangzi and Tianhshenqiao ore blocks within the ore district, this paper points out that the Zhewushe ore block on the eastern limb of Tangzibian syncline has favorable ore-searching prospect and resource potential. |
