The Migration Pattern of Major Elements of the Bauxite in Zhangjiayuan Syncline, WZD Area, Northern Guizhou Province

Abstract

Through various measures such as field geological survey, observation of hand specimens and analysis of major elements, we studied the migration pattern of major elements of the bauxite in Zhangjiayuan Syncline, Wuchuan-Zheng, an- DaoZhen(short for WZD) area of Northern Guizhou Province. The results show that: the Al element was negatively correlated with Si and Fe, but it was not completely synchronous, which indicates the complexity of the mineral transformation during the migration process and the result of superposition of multi-period migration; Al and Ti presented highly positive correlation, and both were relatively stable with certain correlation during the mineralization process; Al was enriched in the central area, Si and Fe presented the tendency of downward aggregation, but the migration scale of elements of the bauxite in Zhangjiayuan Syncline was smaller than that in the karst bauxite in Zunyi.
