OC/N ratio and δ15N both altered significantly due to diagenesis,so OC/N ratio can help discriminate the sources of organic matter in sedimentδ15N can not be used to indicate the origins of the organic matter,and δ13Corg can be a reliable proxy to the sources of organic matter.

用二元混合模型对有机地球化学指标之间的关系进行模拟,结果表明珠江口和近海沉积物样品OC/N与δ15N在早期成岩过程中均发生了较大改变,OC/N可用作判断有机质来源的辅助证据,而δ15N不宜用作沉积有机质来源的指示。
