| Abstract: | In this paper,quantitative analyses of trace elements Sr,Ba,B,Ga,V,Zr contents in bauxite and clay rock and other host rock of the Central-Northern parts of Guizhou are made.The Sr/Ba,B/Ga and V/Zr ratio,correction Boron,equation Boron contents and salinity are calculated.Considering region geological setting and section of ore-bearing rock system,the authors discuss the geological environment of mineralization and point out the difference between Xiuwen Banxite Zone and Zunyi Bauxite Zone:the former belongs to freshen logoon-swamp environment,and the latter belongs to swamp environment of littoral area. |
