本文采用元素分析、红外光谱、扫描电镜和热解分析等手段研究南极布兰斯菲尔德海峡表层沉积物中干酪根的化学和物理性质。南极样干酪根的芳香度与Ｃ／Ｈ原子比呈线性关系。红外光谱特征表明，干酪根中含有大量苯和其同系物如甲苯、乙苯、１，２－二甲苯和１，４－二甲苯等化合物。南极样的热解烃最高仅１．８２×１０－３，总烃平均量０．８９×１０－３，反映了有机质的贫乏。
In this paper, the chemical and physical properties of kerogen in surface sediments of the Bransfield Strait in the Antarctic were studied by means of elemental analysis, infrared spectroscopy, scanning electron microscopy and pyrolysis analysis. Antarctic kerogen aromaticity and C / H atomic ratio showed a linear relationship. Infrared spectral features indicate that kerogen contains large amounts of benzene and its homologues such as toluene, ethylbenzene, 1,2-dimethylbenzene and 1,4-dimethylbenzene. Antarctic pyrolysis hydrocarbons up to only 1.82 × 10-3, the total amount of total hydrocarbons 0.89 × 10-3, reflecting the lack of organic matter.
