| 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. |
