摘要

本文初次提出中国南方早古生界石煤、腐泥煤和沥青煤具明显不同的常量、微量和稀土元素地球化学特征,表明它们具不的成因。腐泥煤和石煤是沉积成因的,而沥青煤是石油热演化的产物。

Abstract

There are lots of bone coal,sapropelite and shungite in the Early Palaeozoic Erathem in southern China.There are different geochemical characteristics in major,micro and REE elements in the bone coal,sapropelite and shungite.The bone coal,sapropelite are rich in Al,Fe,Ca,Mg K,Na,P,Sr,Cu,Zn,Co,Cr and REE,and the shungite is poor in the above elements. There are an abvious positive-Eu anomaly in the shungite and a negative-Eu anomalies in the bone coal and sapropelite.The sapropelite and bone coal are sedimentary origin and the shungite is the product of petroleum evolution.
