Abstract
Taking the Dazhuyuan bauxite ore deposit in the Wuchuan-Zhengan-Daozhen area, Guizhou Province as an example, this paper studies the lithofacies and paleogeography and the relationship between basal palaeogeomorphology and bauxite ore quality. The bauxite ores in the Wuchuan-Zheng' an-Daozhen area are controlled by the sedimentary environment, and are distributed in lakeshore facies, delta facies and shallow lacustrine environments. The bauxite ore quality from the shallow lacustrine environment is the best, and that from the lakeshore facies, delta facies follows. The ore-bearing rock series occurs on the geomorphology of basal shale or carbonate peneplain, and the bauxite ore quality is controlled by material supply and the sedimentary environment, and is also closely related to the geomorphological characteristics of the peneplain. In the low areas of ancient landforms of the basement, the content of Al2 O3 is high, with high Al-Si ratios. The ancient basement terrain, including pit form, size and its depth, exerts a key control on the distribution , occurrence, grade and scale of the bauxite orebodies.关键词
