The cephalopods here described were colleeted from the upper Cambrian Fengshanformation in North China.The vertical istribution of cephalopods is as follows:Inthe lower part of the Fengshan formation is known only a singular genus lectrono-ceras,which seems to be the oldest cephalopod in the known record.This very genuswas found to be associated with rilobites Ptychaspis and Tsinania.Actually,Plec-tronoceras occurred in the Ptychaspis-Tsinania zone,which corresponds pproximatelyto the Upper Franconian F.of North America in age.In the middle part of theFengshan formation,cephalopods are ery abundant locally as seen in the Acaroccras-Aburoceras zone of northern Anhui and in the Sinoeremoceras zone of Liaoning ndsouthern Shantung.The associated trilobites are:Anderssonclla,Changia,Haniwa,Pagodia,Wanwanaspis,Plethopletis.However,no ephalopods have as yet been foundin the Mictosaukia-Coreanocephalus zone(upper part of the Fengshan formation).Therefore,it s suggested that in the Fengshan formation the cephalopod-bearingbeds may be correlated with the Trempealeauan.formation in orth America,and re-garded as of late Cambrian age.A discussion is also made of the early stage of evolution of ephalopods,as shownin fig.1.In the early Fengshanian age(late Franeonian),only Plectronoceras madeits appearance,but in the iddle Fengshanian age(Trempealeauan)cephalopods werelargely developed,which mark their first expansion,amounting to about 30 enerain 7 families and 4 orders in all.From their morphological characters,the four rders-Plectronocerida,Ellesmerocerida,Yanhecerida.and Protactinocerida——seem to bedirectly derived from Plectronoceras.It ould be pointed out that the Ordovician Yehli age(Gasconadian,Tremado-cian)marks a definite stage in the evolution of the phalopods.At the close of theFengshanian age,the essential forms of the Fengshanian cephalopods became argelyextinct,whereas n the Yehli age Endoceroids were flourishing.The two faunas areso great in difference that they ould be easily distinguished rom each other.Thenew materials from the Fengshan formation in North China have provided some evi-dences for tracing out the origin of the major stocks of cephalopods,such as Actino-ceratoidea,Endoceratoidea and Nauticeroidea,For example,the autiloidea is(in arestricted sense)very great in diversity,and may be classified into nine orders,ofwhich the Plectroncerida nd Ellesmerocerida are of primitive forms.In this paper,Special mention is made of the Ellesmerocerida,from which the late remadocian Tarphyeerida and the early Arenigian Oncocerida evolved directly.The Huaihecera-tidae(nov.fam.)of llesmerocerida,being characterized by the exogastrical conchwith marginal siphuncle and orthochoanite septal necks,is imilar o the Basslerocera-tidae.The Tarphycerida and the Oncocerida seem to be directly derived from theBassleroceratidae,which,in urn,came from the Huaiheceratidae.Furthermore these new materials afford the evidences that in late Cambrian toOrdovician ge,the Yellow River sea is the centre of radial evolution,as well as theplace of origin in the history of cephalopoda.The ephalopods here described contain 27 species and 16 genera,of which 26species and 11 genera are new.The diagnosis of the new enera is given as

本文描述了上寒武统凤山组头足类27个种,分属于16个属,5个科。其中2新科,11新属,26新种。除2个种属于原珠角石目外,其余都属于爱丽斯曼角石目。文中对头足类早期阶段(ε_3-0)的系统发生进行了分析研究,编制了系统发生图。并指出我国北方黄河古海盆,不仅是头足类的发源地,而且是头足类早期阶段辐射发展的中心,寒武纪末期一凤山期是头足类发生、发展的很重要的时期;凤山期早期的Plectronoceras 是头足类早期阶段的代表,内角石类,珠角石类,鹦鹉螺类是由它演化而来的。还从头足类演化的角度,讨论了寒武系与奥陶系的分界问题。

Characteristics and stages of evolution of soluble organic matter are discussed in the light of its group composition, chromatogram and infrared spectrum. The formation under review is 6,000 meters thick, accumulated with a rate of sedimentation as high as 0.5mm/year. The bottom hole temperature of the test well is 198℃. Geochemical data available indicate that the organic matter contained in sediments has undergone a fairly complete biochemical and thermal-chemical process of evolution—from the burial of organic deaosits, through immature. mature to highly mature stage of condensates and wet gas, having thus established a direct genetic relationship between organic deposits and oil oecurrence. It is estimated from the data of the well that it takes only 6.5 millions for the organic matter to get matured for oil to occur at the depth of 3,300 meters and the temperature at 126℃. At 5,000 meters with temperature over 172℃ sets in the stage of condensates and wet gas generation The facts disclosed in the study is significant in that they add to the wealth of our knowledge about the subject and provide geochemical criteria for identifying the different stages of conversion of organic matter into hydrocarbons.

本文利用氯仿沥青的族组成,色谱和红外光谱资料,讨论了柴达木盆地第四系至上新统可溶有机质的演化特征及其阶段性。地层厚达6000米,沉积速度高达0.5mm/年,井底地温高达198℃,各项地化资料表明,沉积中的有机质经历了一个相当完整的连续的生物化学和热化学的演化过程——从有机质沉积埋藏开始,历经未成熟、成熟至达高成熟的凝析油和湿气阶段;从而确立了有机物沉积和成油之间直接的成因联系。该井有机质沉积到成熟只用了650万年时间,成油临界的井深为3300米,地温120℃;当埋深达5000余米,地温172℃以上时,则已经进入凝析油和湿气阶段了。

The basin at the mouth of Pearl River is a large sedimentary basin primarily of Tertiary origin, having undergone three stages of evolution: from late Cretaceous to early Oligocene, from middle Oligocene to early Miocene and from middle Miocene to Quarternary. The basic structural patterns formed in the basin include three types of depression and two types of uplift, either of fluviolacustrine, or of semi-closed sea, or of open sea deposition. They have plentiful oil source, good reservoir properties and excellent capping and trapping conditions very well associated. All this suggests that the basin at the mouth of Pearl River is provided with the basic structural conditions to form a large oil and gas basin with great potentialities.

珠江口盆地是一个大型新生代为主的沉积盆地,它经历了晚白垩世至早渐新世、中渐新世至早中新世、中中新世至第四纪三个演化阶段。以及由此而形成的基本构造模式——三种拗陷和两种隆起;基本沉积模式——河湖、半封闭海、开阔海三种沉积体系;有良好的生油、储油、盖层和圈闭条件及其相互配合关系。因此,珠江口盆地具备了一个大型含油气盆地的基本地质构造条件,有很大的油、气潜力。
