【 摘 要 】

By analysing features of trace elements in ZK-CS1 Laowashan Bauxite of Zunyi by geochemical methods, it was found that these elements could be divided into four types according to features of their vertical distribution. For instance, the content of elements such as Ga, Li and Sc was relatively low in the middle part of the ore-bearing rock series, but increasingly higher towards the top and bottom, and the highest at the bottom or near the bottom. Nb and Ta, Zr and Hf migrated in pairs during metallogenesis. The dolomite in the underlying Loushanguan Formation of the ore-bearing rock series was one of provenances of the Laowashan bauxite.
