The Jurassic system of China—Main characteristics and recent advances in research

In China, the marine Jurassic is mainly distributed in the Qinghai-Tibetan Plateau, southwestern China and environs including southwestern Xinjiang and western Yunnan. Along the western palaeo-Pacific coast, marine Jurassic deposits, which usually intercalate with nonmarine strata, exist sporadically in eastern Heilongjiang, western Fujian, Hongkong, central Guangdong, western Jiangxi, eastern and southwestern Hunan Province, and probably also in western Taiwan. Nonmarine Jurassic strata are widely distributed in the whole of China except for southern Tibet area. They are commonly intercalated with volcanic rocks and contain volcanic materials in eastern China, and in southern Tibet. Marine strata yield various abundant fossils including ammonites, which were widespread in the Tethyan Realm even all over the world. Consequently, China is a critical region to attempt marine and non-marine Jurassic correlation. Through various investigations, both marine and non-marine Jurassic biozonations or assemblages have been established and by this the marine and non-marine Jurassic stratigraphic system and their correlation in China have been clarified.

Discussions on the age of the Daohugou fauna—evidence from invertebrates

Volcanic tuff deposits near Daohugou village, Ningcheng County of Inner Mongolia have yielded many wellpreserved fossils. Here we briefly introduce our recent findings of invertebrates from the Daohugou fauna: mainly insects, conchostracans, anostracans, and spiders. The age of the Daohugou fauna is considered to be Middle Jurassic on the basis of an analysis of various invertebrates especially insects and conchostracans, showing strong similarities to the Yanliao fauna of north China and the Karatau fauna of Kazakhstan.

泰国呵呖高原盆地油气成藏组合与资源潜力

针对海外含油气盆地勘探程度较低、资料相对匮乏的问题,以呵呖高原盆地为例开展了成藏组合及油气资源潜力研究,研究中以构造沉积演化成藏的递进控制作用为核心,获得了以下认识。晚古生代新生代,盆地构造演化可划分为两期构造层序TS1和TS2;其中,TS1构造层序内主要充填浅海相滨岸、陆棚、碳酸盐岩台地沉积,TS2构造层序内主要充填陆相冲积扇、河流、湖泊沉积;沉积相控制下盆地内发育两套主要的生储盖组合,结合盆地的主要圈闭类型,进一步划分出已证实二叠系和远景三叠系两个一级成藏组合,4套二级成藏组合;在下一阶段的勘探中,纵向上应侧重于二叠系一级成藏组合的天然气勘探,平面上应重视以Phu Phan隆起为主的盆地中部及以Khorat次盆北部和Sakhon Nakhon次盆西部为主的盆地西部地区,前者发育二叠系一级成藏组合最有利油气勘探区,后者为三叠系一级成藏组合最有利油气勘探区。     

西藏聂拉木县聂聂雄拉地区早、中侏罗世双壳类动物群

西藏聂拉木县聂聂雄拉地区，早、中侏罗世地层较发育，地层中化石属 种繁多。地层划分为下侏罗统“普普嘎组”，中侏罗统聂聂雄拉组和拉弄拉组。作者研究了该区旱、中侏罗世的双壳类动物群40多属80多种。描述双壳类化石8新种：Tancredia(T.)nyalamensis,Hiatellasubtrigona,Pronoella(P.)minima,Opis(O.)curvus,Costigeruillia tetracostata,Weyla costalliformisa,Entolium obliquus,E.subfilosus,刊出部分化石图版，简述双壳类化石组合特征。它的研究对该地区旱、中侏罗世地层划分对比，生物地理分区和动物群特征的认识都具有一定的理论与实践意义。     

百花山兽类区系特征及生态分布

１９８９～１９９１年对百花山自然保护区的兽类区系进行了比较系统的调查，共记录到６目１３科２５种．整个区系以古北界成分为主，占６８．０％，同时也呈现出比较明显的南、北两方动物分布的过渡特征．本文从地理分布特征出发，对本区兽类区系的组成进行了比较详细的分析，并讨论了这些兽类的生态分布和垂直分布状况以及鼠形动物的季节变化．
