The analysis of TOC andδ13Corg benefits from Well Chao-73, indicating that they response well enough to the Cretaceous paleoenvironment and paleoclimate. During the sedimentary period of Quantou formation to Qingshankou formation in Songliao basin, the water tends to rise and becomes anoxic, and the deoxidized water leads to the organic matter massively preserved. The paleoclimate changes from torridity and aridity to warmth and humidity, with the temperature evidently descengded, then ascended in a litter range. The result is basically consistent with paleoclimate by the palynological analysis.

朝73井TOC、δ13Corg有机地球化学指标的分析结果表明，TOC、δ13Corg的变化对该沉积时期的古环境、古气候也有很好的响应，该沉积期湖水位不断上升，湖生生物逐渐发展并繁盛起来，水体含氧量减少，湖底有机质的保存环境逐渐变为强还原环境，大量有机质被埋藏并保存，而古气候在泉头组/青山口组界线上下由炎热干旱变得温暖湿润，气温有明显下降，但随后又有小幅的上升，与孢粉分析的古气候变化特征基本一致。

Using the latest paleontological, magnetostratigraphic and chronological data and the lasting time of the high-resolution sequences, the authors have made a detailed chronostratigraphic division of the Jixi Group and determined the Jixi Group formed in the Early Cretaceous early Valaginian to middle Albian. In the group, the Didao Formation formed at 130.9±128.3 Ma, the Chengzihe Formation at 125.1±116 Ma, the Muling Formation at 116±106.9 Ma, and the Dongshan Formation at 106.9±101.7 Ma.

提要：利用最新的古生物、磁性地层年代资料及高分辨率层序延续时间推算，对鸡西群进行了精细的年代地层划分，确定了鸡西群形成时间为早白垩世凡兰吟早期—阿尔布中期，其中滴道组形成时间为130.9～128.3 Ma，城子河组形成时间为125.1～116 Ma，穆棱组形成时间为116～106.9 Ma，东山组形成时间为106.9～101.7 Ma。

Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian～early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .

侏罗纪末～白垩纪初印度大陆的北缘同时期存在大陆向上挠曲，导致陆源碎屑输入量的快速增加，石英砂岩广泛存在；早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深，使得较深部的深成火山岩暴露并遭受侵蚀；石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&，说明构造运动首先是从特提斯喜马拉雅的东部开始（大印度与澳大利亚的彻底分离），然后逐渐波及西部的，东西时间差为15～20Ma；由于地壳均衡作用，大陆分离后原先地壳挠曲转变为地壳下沉，发生强烈的构造沉降，故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。

Important spore and angiospermae pollen fossils such as Asterisporites,Cranwellia,Xinjiangpollis,Beaupreaidites and Quantonenpollenites have been obtained from the the upper part of the Member 4 of Quantou formation. They are Late Cretaceous in age. The reasonable geologic time of the upper Quantou formation may be later than Cenomanian deduced by the age of the upwards spore and angiospermae pollen fossils and the palynological assemblages.
