Geochemical Characteristics of Ore-Bearing Strata of Pb-Zn Deposits in the Sichuan-Yunnan-Guizhou Border Area in Southwest China

Abstract

The Pb-Zn deposits (or points) with different ages of ore-bearing strata are counted in in the paper. Through discussing the lithology and elemental geochemistry in ore-bearing strata to explain the lead element and zinc element relate to strata and lithology, the author suggested the lead-zinc deposit mainly were exposed in specific stratum, considering the deposits was obviously was controlled by stratum and was greatly influenced by lithology. For this reason, combining with the comparative study of element abundances in rock, it has maily demonstrated the relevance of ore-forming elements.
