侏罗系的

Through statistical analysis of the rock mechanic properties of upper Jurassic and Cretaceous red mudstones, siltstones and sandstones in the middle Sichuan Red Basin, the range of their compressive strength, the features of the shearing strength and of the deformation curves are proposed in this paper.

From the research of the kerogen carbon isotopes of the coal-measure strata in some basins of China (the Carbo-Permian in the Ordos basin, the Triassic in the Sichuan basin, the Jurassic in the Jungar basin and Turpan-Hami basin, the Tertiary in the Yingqong basin) it can be indicated that the Type Ⅲ kerogen has a wide δ〓C range from -21. 2‰ to -27. 6‰, averaging -25‰, which is more enriched in 〓C than sapropel and mixed kerogens.

对我国一些含煤盆地（陕甘宁石碳－二叠、四川三叠系、准噶尔侏罗系、吐哈侏罗系、莺琼盆地第三系）的煤系地层干酪根碳同位素研究表明，煤系地层的干酪根碳同位素组成δ〓C值分布范围为－21.2～－27.6‰，说明其变化范围较宽，平均值为－25‰左右，相对腐泥型干酪根和混合型干酪根较明显地富重碳同位素。

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。
