| 7. | The paper adopts some methods such as gas composition , carbon isotope , systematical analyzing and testing of reservoir bitumen biomarker from high evolutional natural gas and quantitative calculation of mixed gas , illustrates that natural gas from the section of jialingjiang formation is mainly attributed to sapropel type organic matter gas of permian , comes from carbonatite hydrocarbon rocks permian which most of them are overmature , its main gas source has nothing to do with carbonatite hydrocarbon rocks of jialingjiang formation themselves , presents in geochemistry characteristics of oil type cracked gas 摘要通过对川中川南过渡带西部的磨溪潼南地区嘉二段天然气组成、碳同位素组成、高演化天然气储层沥青生物标志化合物的系统分析测试和混合成因气的定量估算,阐明了该区嘉二段天然气主要属于二叠系腐泥型有机质成因气,来源于二叠系过成熟为主的碳酸盐岩烃源,主力气源与嘉陵江组自身的碳酸盐岩烃源无关,并具有油型裂解气的地球化学特征。 |
| 8. | The comparison of stomatal parameters in leaf cuticles between two fossil angiosperms from the pliocene in west yunnan and their nearest living equivalent species indicates a little higher atmospheric co2 level at that time than the present , while carbon isotopic composition of fossil cuticles demonstrates much higher carbon isotopic discrimination and slight lower water use efficiency , showing a warmer and wetter climate than today 摘要对滇西腾冲新近纪两种被子植物叶片及其现存对应种的气孔参数和碳同位素组成的综合分析表明:当时的大气co2浓度略高于现在水平;化石种的碳同位素分馏值高于现存对应种,但水分利用效率低于现存对应种;这证明当时的气候条件比当前更为温暖湿润。 |
