利用绥滨勘查区早白垩世鸡西群城子河组煤质测试资料，从地球化学研究分析角度，对研究区煤中有机元素含量、有机元素原子比分布特征及与挥发分产率、埋藏深度、煤化作用程度的关系进行研究，结果显示，区内煤中有机元素含量高度离散，除受泥炭沼泽环境条件影响外，还受叠加变质作用影响；煤化程度增高，深成变质煤O/C原子比与H/C原子比趋于降低，且前者明显；在煤化作用过程中煤中有机氮难以脱除而有机硫易于逸出。

Based on coal quality tested data of coals in Lower Cretaceous System Jixi Group Chengzihe Formation in the Suibin explora-tion area, from the view of geochemistry, carried out study on relations between coal organic element content, atomic ratio distribution features and volatile matter yield, buried depth, degree of coalification. The result has shown, coal organic element content in the area is highly dispersed, besides impacts from peat bog environment, as also from superimposed metamorphism. Along with increasing of the coalification degree, atomic ratios O/C and H/C of hypozonally metamorphosed coal tend to decreasing, while the former is more obvi-ous. During the coalification process, organic nitrogen in coal is hard to get rid of and organic sulfur easy to escape.
