| Abstract: | In this paper,the sedimentary environment of the bauxite deposits is mainly dense -flow sediments bordered on the closed lagoon on the basis of analysis and study on sedimentary sequence, lithological texture, sedimentary structure and grain size of Changchong bauxite deposits ,xiuwen County. This sedimentary type is first discovered in Central-Guizhou, being significance to the prospecting of bauxite deposits in Guizhou province. |
