海相沉积

稀土元素标准化配分曲线呈现出轻稀土富集、重稀土平坦和明显Eu、Ce负异常特征，类似于上地壳和典型太古代页岩，具有海相沉积特征。

The REE patterns of analyzed sediment rocks in the Pingxiang basin are similar to those of the upper crust and typical Archean shales , and show enriched LREE and flat HREE with obvious Eu-and Ce-anomalies .

通过对含硼白云质大理岩C、O同位素及B同位素地球化学进行分析显示了该矿床海相沉积碳酸盐岩的特点，地层及矿体中的硼质同来源于深部。

Analyzing the Geochemistry of C 、 O isotopes and B istope in boracic dolomitic marble , it can be seen that the ore is marine sediment carbonate type , that is , the boron in the layer and in the ore came from the depth .

一般来说，元素Cu、Zn、Ni、P、Ba等在海相沉积中富集一般与内源有关，所以地球深部流体对有机质的富集和保存具有一定作用。

Generally speaking , the enrichment of Cu , Zn , Ni , P , Ba are related to the inner matter of the earth , so the fluids of interior earth has some effect on the enrichment and preservation of the organic matter .

而此线以东的地区Z值＞120，δ18O、δ13C均说明为海相沉积，与以前的沉积环境研究结论一致。

The Z ( > 120 ), 18O and 13C values in the areas to the east of the line show that the sedimentary rocks deposited in marine environment , which is corresponding to the results of sedimentary environment studies obtained earlier .
