A study on Pb isotopic characteristics of raw bauxite in western Guangxi, China

The Pb isotopic composition of ores is one of the important approaches to trace the ore sources. It has not yet been applied to research on bauxite ore so far. The current research on bauxite deposits in western Guangxi, China, seldom focuses on raw bauxite and studies on raw bauxite are mostly at macro-level. This study is the first to apply Pb isotope data to tracing bauxite ore sources. The Pb isotopic compositions of ore and rock samples from the Nadou and Taiping mining districts are projected on the Doe and Zartman plumbotectonic models and the results showed that the ore resources are different for the two mines.
