  • Bauxite deposit in Wuzhengdao of Qianbei, which is the biggest bauxite deposit of China, is sedimentary type bauxite, which is affected by facies and change of sea level. Based on analysis of lithology and geochemistry of bauxite-bearing rock series in the study area, the bauxite is formed in shore lake and shallow lake. So the bauxite is deposited in fresh water. The chlorite rock and bauxite rock are deposited in fan delta and tidal flat facies. The hydrodynamic condition determines types and grade of bauxite. Grain bauxite is formed in strong hydrodynamic condition, soil type bauxite is formed in weak hydrodynamic condition. The chlorite rock and bauxite rock are deposited during rise of sea level, and bauxite is deposited during drop of sea level. The span of drop period is much greater than rise period, which explains why forming of bauxite is a long weathering progress. Up to three cycles can be identified during deposit of bauxite-bearing rock series, and the three cycles are consistent with corresponding period deposit of carbonate rock and clastic rock in adjacent area.

Abstract: Bauxite deposit in Wuzhengdao of Qianbei, which is the biggest bauxite deposit of China, is sedimentary type bauxite, which is affected by facies and change of sea level. Based on analysis of lithology and geochemistry of bauxite-bearing rock series in the study area, the bauxite is formed in shore lake and shallow lake. So the bauxite is deposited in fresh water. The chlorite rock and bauxite rock are deposited in fan delta and tidal flat facies. The hydrodynamic condition determines types and grade of bauxite. Grain bauxite is formed in strong hydrodynamic condition, soil type bauxite is formed in weak hydrodynamic condition. The chlorite rock and bauxite rock are deposited during rise of sea level, and bauxite is deposited during drop of sea level. The span of drop period is much greater than rise period, which explains why forming of bauxite is a long weathering progress. Up to three cycles can be identified during deposit of bauxite-bearing rock series, and the three cycles are consistent with corresponding period deposit of carbonate rock and clastic rock in adjacent area.
