摘要
Based on the field geological survey,element chemical analysis and other methods,it is found that V-U polymetallic elements are enriched in the lower Cambrian black rock series,especially in the stone coal.Additionally,REE is characterized as relatively rich in light rare earth,high fractionation of light and heavy rare earth allow,and negative anomalies of Ce,Eu.This series of black rock should be deposited in reducing environment and dry climate of the continental margin.
