Ore-forming fluid system of bauxite in Zunyi area of northern Guizhou province, China

Abstract

The ore-forming fluid system of Laowashan bauxite in Zunyi area of northern Guizhou Province was studied through field geological survey and observation of hand specimens. It was concluded that surface runoff, atmospheric precipitation and sea level changes played important roles in the formation of the aforementioned bauxite. Under the impacts of vertical leaching of ore-forming fluids, industrial bauxite deposit and pyrite deposit formed in the upper and lower parts of the ore-bearing rock series respectively.
