云南水系沉积物磷地球化学特征及其指示意义

Geochemical characteristics of P in stream sediments and its geological implications in Yunnan province

摘要: 通过对云南省水系沉积物磷地球化学特征进行研究，发现地层以震旦-寒武系中磷含量最高，岩浆岩以碱性岩中磷含量最高，基性岩次之，同时磷地球化学异常充分继承了地质体的地球化学特征，对磷矿、峨眉山玄武岩、碱性岩具有明显的指示作用.

Abstract: Researching on the geochemical characteristics of P in stream sediments in Yunnan province,we found that P content in Sinian-Cambian is higher than other strata,the P content in alkaline rock is highest in volcanic rocks,follow is basic rocks.The characteristics of geochemical anomalies of P are well inherit from the geochemical characteristics of geological body,have obvious implication of phosphorite,Emeishan basalts and alkaline rock.
