摘要：

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。

Abstract:

The chemical and physical properties of kerogen in surface sediments from Bransfield strait were studied by using elementary analyzer,infra red spectroscopy,electron microscopy and pyrolytic analyzer.The results indicate that the relation between aromaticity and atomic retio of C/H are linearly dependent.There are large amount of benzene homologue compounds as toluene,ethyl benzene,o xylene and p xylene.The production ability of hydrocarbon are poor.The average content of the total hydrocarbon (S 1+S 2) are 0.89×10 -3 .
