云南会泽大黑山铝土矿地球化学特征及其物源分析
Geochemistry and provenance analysis of the Daheishan bauxite deposit in Huize, Yunnan
摘要
Abstract
The Daheishan bauxite deposit in Huize, Yunnan resides in the basal part of the Upper Permian Xuanwei Formation underlain by the Emeishan basalts. The bauxite ores from the Daheishan deposit display micritic, oolitic and granular textures, and densely massive, stratified and stratoid structures. There are both negative correlations between Al2O3 and Fe2O3 , and Al2O3 and SiO2 and good correlations between TiO2 and Zr, Hf, Nb and Ta, Zr and Hf, Nb and Ta. The bauxite and basalt samples in this study exhibit similar normalized distribution patterns. The ore-forming matter may be derived from the underlying Emeishan basalts, as indicated by LogNi and LogCr diagram.关键词
