黔北务正道地区铝土矿沉积特征及分布规律
Sedimentary Characteristics and Distribution Features of Bauxite in Wuchuan-Zheng'an-Daozhen Area, Northern Guizhou Province
摘要
Abstract
Through the research of structure of the bauxite, distribution of different types bauxite and reference paleogeography data, we considered that different natural types of the bauxite showed different environment. Massive and half-earthy bauxite indicated low energy environment. Clastic and oolitic bauxite indicated the high energy environment of shoreland. The distribution of the bauxite was influenced by grain size grade. Clastic and oolitic bauxite around the study area were dominant in Xinmo, Zhangjiayuan and Anchang synclines. Massive bauxite was widely distributed in the study area. Massive and half-earthy bauxite gradually increased from south to north. The bauxite was formed in a lake or a partly closed bay which was influenced by the frequently transgression and regression, and sea water access the study area from north to south. Eluviation after bauxite deposit improved the grade of the bauxite ores.关键词
