1.
In view of types,abundances and thermal evolution properties on organic matter,an evaluation of the hydrocarbon source rocks of the lower and middle Jurassic in Tula basin is made.
通过对吐拉盆地中-下侏罗统烃源岩有机碳含量、可溶有机质含量、热解参数、干酪根显微组分、干酪根元素、干酪根炭同位素、镜质体反射率等方面的分析,讨论了烃源岩的有机质丰度、类型和成熟度。
2.
On the basis of biomarkers in the lower and middle Jurassic source rocks from the Tula basin,it can be seen that these samples at least have reached maturation stage during their thermal evolution,and the organic sources are mainly from terrestrial higher plant combined with abundant aquatic organisms input.
对吐拉盆地中下中-下侏罗统烃源岩饱和烃中正构烷烃、类异戊二烯烷烃、甾萜烷类化合物研究表明,研究样品的有机质演化至少处于成熟阶段,其母质来源以丰富的高等植物输入,同时也有一定比例的低等水生生物输入为特征,泥岩沉积时为微咸水较强还原沉积古环境。

吐拉盆地是位于柴达木盆地西南、塔里木盆地东南、可可西里山脉以北的一个盆地,该盆地海拔3000m以上,人烟稀少,勘探程度很低。
补充资料:磨拉石
磨拉石 molasse 地槽急剧隆起,形成于山前坳陷的巨厚的以粗碎屑为主的一套岩系。又称磨拉层。其成分中砾岩占70%~80%,含砂岩、灰岩、泥灰岩、页岩、盐类、煤等。岩层松软,厚度巨大,常见交错层和波痕,相变急剧。以陆相沉积为主,也有海相和海陆交互相沉积。成分变化有一定规律,从山区到平原往往由砾岩过渡为砂岩、粉砂岩、粘土岩;纵向上,从上到下由陆相过渡为海相。主要发育于造山运动的隆起阶段,分布于山前坳陷地带。有些地带由于地壳活动性较弱,其磨拉石的发育程度不全,称为类磨拉石。中国北祁连山地区的老君山砾岩被认为是典型的磨拉石。岩系下部为砾岩、砂岩,上部为砂岩、页岩。molasse一词源于法语,1919年瑞士地质学家A.海姆首次提出。 |
