矿石铅同位素组成是示踪矿石来源的重要手段之一。目前尚未应用于铝土矿的研究。目前对桂西铝土矿的研究还很少涉及到原生铝土矿，对原生铝土矿的研究多停留在宏观层面。本研究首次将铅同位素资料应用于铝土矿矿源示踪。根据Doe和Zartman铅构造模型对南斗和太平矿区矿石和岩石样品的铅同位素组成进行了预测，结果表明两矿区的矿石资源量不同。
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.
