通过对渝南水江板桥铝土矿区五个典型探槽中铝土矿（岩）和稀散元素锂的研究，发现Al2 O3主要分布在含矿层位的上部和中上部，其矿石类型主要为豆（鲕）状和砾屑状，锂主要分布在含矿层位的上部和中上部，主要赋存的岩石类型为砾屑状高铝黏土岩。Li含量在200～1400×10-6之间，平均含量为830．23×10-6；Li在铝土矿含矿岩系上部和中上部的高铝黏土岩中最为富集；铝土矿矿石中Li含量较高，平均为531．37×10-6。Li与Al2 O3相关系数平均值 r＝0．820，为正的强相关；Li与SiO2相关系数平均值r＝-0．653，为负的中等相关；Li与A/S比值的相关系数平均值 r＝0．885，为正的强相关。在渝南铝土矿含矿岩系中，Li矿层的形成受层位、矿石类型的影响。

Based on the study of the bauxite and Scandium of Shuijiangbanqiao mine in Southern Chongqing ,the Al2 O3 was found distribute mainly in the upper and middle-upper layers ,the main type of bauxite are pisolitic ,olitic structures and massive structures .The Lithium was found distributed mainly in the upper and middle-upper layers ,the main type of bauxite is massive bauxite .Lithium is changing from 200 to 1400 × 10-6 and average in 830 .23 × 10-6 .The content of Lithium which is higher in Aluminum clay than in bauxite .The average of correlation coefficient r=0 .820 between Lithium and Al2 O3 ,it is a severe plus correlation .The average of correlation coefficient r= -0 .653 between Lithium and SiO2 ,it is a moderate negative correlation .The average of correlation coefficient r=0 .885 between Lithium and A/S ,it is a severe plus correlation .The seam of Li was affected by horizons ,the impact of ore types ,southern Chingqing , China .
