沉积岩有机质的红外光谱及其在石油有机地球化学中的初步应用 总被引:1,自引:1,他引:1
Types and degree of muturity of organic matters in sedimentary rocks as index for oil generation and evolution can be determined by infrared spectrometry. In normal cases,oil-generating rocks can be preliminarily identified by infrared spectra of solubable bitumen components. However, the spectra of condensed nuclei of aromatic hydrocarbon should be resorted to whenever the composition and structure of organic matters arc comparative complex and their degree ofmuturity are not all the same. Systematic researches of known samples show that a configuration of condensed aromatic hydrccarbon can be proposed on the basis of the index of aromatic hydrocarbon structure and the ratio of methyl and methylene to aromatic nucleus. It is evidenced by preliminary experience that oil- and coal-generating organisms can be distinguished from each other with the help of this configuration. 相似文献

Using X-ray photoemission spectroscopy (XPS), the Preliminary results on the lunar basalt sample (70017-291)are shown in the paper. Major elements (O, Si,Al, Fe, Ca, Mg, Ti, etc.) of the lunar sample are similar to that of the Jilin meteorite and the Allende meteorite. The valence of iron in the sample has also been studied in detail. The authors suggest that Fe^ may be differentiated from Fe^ in the XPS spectra in terms of the satellite lines of Fe(2p3/2). 相似文献

茂名油页岩中生物输入的标志化合物 总被引:19,自引:2,他引:19
我国油气的绝大部分产自东部地区的白垩纪与第三纪合油气盆地,其沉积环境多为陆相,陆源高等植物输入较丰富,介质条件以淡水一半咸水为主。在这方面茂名油页岩具有典型的代表性,因而深入研究其生物标志物特征与有机输入模式,对建立适用于我国油气勘探的分子有机地化参数以及发展我国陆相生油理论具有重要的现实意义。 相似文献

形成于贫营养型高地沼泽的云南金所泥炭藓软褐煤的链烃主要由正烷烃组成,异戊二烯类烃含量甚低,含少量陆源三萜烯。芳烃馏分主要由三芳,四芳三萜类和两个未知化合物组成。前者具典型陆源输入的奥利烷或乌散烷分子骨架,褐煤Rren^0仅0.24%,但芳构化作用已十分强烈,且芳烃主要由芳构化陆源三萜类组成。 相似文献
