摘要
The Xiaotianjing manganese deposit possesses the largest reserves, and is the earliest exploited mine in the Heqing area, Yunnan Province. This study collected 60 samples from the manganese-bearing rock series to conduct trace element and REE analysis, and discussed their characteristics and relationship to sedimentary environments. By using the multivariate statistical correlation analysis and factor analysis, this work found that the elements Mo, U, V, Mn and Zn constitute an important ore-forming element assemblage in the mining area. This is of great significance for discriminating ore potentialities of the strata and structures and determining concealed orebodies. Analysis of the Co/Ni, Sr/Ba, and Th/U suggests that the manganese layer materials were derived from terrigenous sources, and the depositional environment was an offshore continental margin.
