Abstract:
末元古纪以Cloudina为代表的管状动物化石是目前世界上公认最早的具矿化骨骼的生物类群,在世界许多地区都有发现,但它并不是当时唯一的矿化生物类型,更多的动物骨骼化化石证据在寒武纪大爆发之前的沉积物中时有发现。作者在处理陕南末元古纪的化石过程中,发现了大量不同形态的微体管状化石(直径大多小于150μm),包括末端封闭的粗短管体,不分枝管体,末端扩展的骨针状构造及具多种分叉样式的分枝管体。这些化石的亲缘关系仍不清楚,但它们为我们提供了动物演化和矿化初始阶段的化石记录。

Abstract:
$$In the Late Jurassic strata of Himalaya, South Tibet, there are abundant buchiids. As has been known in other regions of the world, the strata in which buchiids are abundant are usually characterized by scarcity of other fossils except for a few belemnites and ammonites. Therefore, buchiids can be regarded as an useful biostratigraphic tool in these intervals without ammonites and other fossils. In our working area, four buchia assemblages have been recognized. And a comparation has been made with other regions of the Spiti and North America. In addition, an attempt is made to explore the biostratigraphic value of buchiid.

Abstract:
记述甘肃酒泉盆地早白垩世地层中发现的两种掌鳞杉科植物化石Pseudofrenelopsis dalatzensis(ChowetTsao,1977)Cao ex Zhou和P.gansuensissp.nov.。其中,归入P.dalatzensis的标本无论是小枝形态还是表皮构造都与产于吉林延吉盆地大砬子组的模式标本一致。定为新种的标本小枝较粗,可能只有一枚叶;节间角质层厚25—30μm,表面没有乳突和表皮毛,气孔器和表皮细胞均规则成行排列;气孔器圆形或椭圆形,较大,整体下陷。副卫细胞通常5—7个,少数可达8—9个。保卫细胞仅部分保存。已发现的Pseudofrenelopsis均分布于北半球,时代限于早白垩世,且多为早白垩世晚期,其中P.dalatzensis在模式标本产地与丰富的被子植物共生,应为早白垩世Aptian到Albian期。该种在酒泉盆地中沟组的出现说明该组的时代最高可到Aptian或Albian期。已有资料还表明,Pseudofrenelopsis主要生活于有季节变化、盐度较高或较干旱的环境中,这与酒泉盆地早白垩世沉积物和其他门类的化石所指示的环境特征相符合。

Abstract:
The Middle Jurassic flora from the Xishanyao Formation in Baiyang River area of northwestern Junggar Basin, Xinjiang, China comprises 39 species belonging to 24 genera, so far as known. 25 species of 15 genera are described in this paper. Among them, the spores in situ Coniopteris hymenophylloides with their sporangia and sori are found for the first time in Xinjiang. Anatomically, the cuticles of the leaves of Phoenicopsis (Phoenicopsis) angustifolia are also first studied with SEM in this area. The present flora is characterized by dominance of ferns, czekanowskiales, ginkgoales and conifers, and scarcity of bennettitales and cycadales. The flora belongs to a typical inland flora probably reflecting a warm-temperate climate. The geological age of the flora is Middle Jurassic and might be the early Middle Jurassic. Paleophytogeographically, the flora belongs to the Siberian Region of the Early-Middle Jurassic Eurasian Realm, indicating a warm and humid climate with seasonal changes, which was favorable for coal formation.

Abstract:
中二叠世的Eopolydiexodina-Rugososchwagerina类动物群是一个具有重要地层及古地理意义的动物群,也是滇西保山地块沙子坡组的一个指示性动物群。文中详细研究了耿马小新寨沙子坡组“Rugososchwageri-na”标本的形态学特征,阐明了其与RugososchwagerinaMiklukho-Maklay,1956的模式标本在特征上的显著区别。依据幼壳形态特征在类个体发育及系统发生研究中的重要性,对小新寨“Rugososchwagerina”标本的属级分类提出质疑,并建议建立新属Xiaoxinzhaiellagen.nov.。

Abstract:
The foraminiferal materials described and figured in the present paper were collected from the Permian Da'aozi Formation in Woniusi Section of Baoshan area, western Yunnan. Systematic study shows that the characteristic genera, i.e., Shanita and Hemigordiopsis, of the Shanita fauna in Baoshan area contain 8 species, including 2 new species. Besides, 10 other genera of non-fusulinid foraminifers have also been recognized from the fauna. Further study has revealed that the Shanita fauna in Baoshan area can be correlated to those from Burma, Peninsular Thailand and Tibet with an age of late Maokouan (Lengwuan) to Wuchiapingian. However, the relatively lower generic diversity and occurrence of some endemic species, as well as the absence of fusulinaceans may indicate the regional characteristics of Shanita fauna in Baoshan area.

Abstract:
叶状藻类是广泛分布于石炭-二叠系的钙质藻类,相关研究主要集中在美国。根据产自云南石林地区茅口组的标本,建立并描记了藻体巨大、表面具有独特纹饰、内部可能具有生殖构造的一新属Archaeoudotea和新种Archaeoudotea shilinensis;其系统归属虽然有待于进一步研究证实,但新属可能属于红藻的珊瑚藻类,营底栖固着生活于水能量较弱的碳酸盐台地。

Abstract:
苏北盆地是我国西部高原至东部海洋之间的过渡地区，该地区的气候演变史对揭示东亚季风的时空变化有着重要的意义。根据气候地层学的原理，用孢粉分析的方法，结合^14C测年数据，再造了兴化地区自倒数第二次冰期以来的古植被与古环境，其演变史能与深海氧同位素记录进行良好的对比，孢粉带Ⅲ、Ⅳ、Ⅴ、Ⅵ、Ⅶ分别对应深海氧同位素阶段5、4、3、2、1，且孢粉带Ⅲ细分的5个亚带与MIS 5a-5e也有良好的对应。此外，从该地区末次冰期孢粉记录中检索出6次冷事件，通过与格陵兰冰芯及会宁黄土记录对比，推测这些冷事件可能对应于末次冰期气候变化中的Heinrich事件。

11 THE ROLE OF TRACE FOSSILS IN DETECTING THE PALEOGENE ESTUARY ENVIRONMENT AND INCISED VALLEY OF DONGPU DEPRESSION, EAST CHINA

[Abstract](366) [HTML](0) [PDF 0.00 Byte](5)

Abstract:
Paleogene deposits in Bohai Basin have long been considered of terrestrial origin and the reservoir depositional environments have thus been treated as fluvial and lacustrine related facies. However, evidence of marginal marine trace fossils from Dongpu Depression, the southmost of the Bohai rifted basin, shows that marine water incursion might have happened several times and a Paleogene seaway might have been existed correspondingly during the highstand periods; in lowstand periods, the original very shallow marine sedimentary setting became lakes in the structurally low area and eroded rivers scattered in palaeovalley districts which have developed from incised drainage. Trace fossil records in fresh water, salt water and marine water deposits related to an estuarine environment are found for the first time in this region. The importance of ichnological records associated with sedimentary evidences are strongly emphasized here in terms of prospecting a seaway related new type reservoir.
