1笔石、几丁虫和虫牙反射率在热成熟度上的应用显示文摘根据中国湖北黄陵背斜周缘11条奥陶纪、志留纪地层剖面的笔石,几丁虫和虫牙反射率的研究,结合相同或邻近层位牙形石色变指数(CAI)和分散有机质成熟度的红外光谱鉴定,进一步证明:笔石、几丁虫和虫牙的反射率具有随成熟度增加而增加的特点以及各自不同的反射率径迹,因此,在不含镜质组的前泥盆纪地层中,它们可以作为热成熟度的指示。笔石具有明显的各向异性的光学特点,在平行层面所切笔石光面上测量笔石最大油浸反射率,对确定含化石母岩的成熟度最为合适。几丁虫和虫牙具有各向同性的光性特点,因而它们的光面仅显示反射率而无双反射率。笔石、几丁虫和虫牙反射率分布趋势的分析表明,可以将本区奥陶系与志留系划分为3个成熟度区。并对各区形成油气的潜在可能性进行了讨论,其结果与牙形石色变指数和有机质红外光谱分析,所证明的区域有机质成熟度分布模式基本一致。汪啸风 Andreas Hoffknecht 萧建新 陈善庆 李志宏 Rainer.Brocke Bernd-D Erdtmann 1992地质学报1992,66,3:19
2Eocrinoid echinoderms from the Lower Cambrian Guanshan Fauna in Wuding,Yunnan,China显示文摘This is a brief report of a new occurrence of eocrinoids from the Early Cambrian Wulongqing Formation in Yunnan, China. The eocrinoids from the Guanshan fauna are among the earliest known eocrinoids. Different from many other Early and Middle Cambrian eocrinoids, the Guanshan eocrinoids are char-acterized by the absence of sutural pores and epispires, the long and spiral brachioles, the extremely long stalk, and the ratio of the length of the stalk versus that of the calyx. The discovery of the eocri-noids from the Guanshan fauna not only provides new information to the investigation of the early evolution of this animal group, but also shed new light on the occurrence and migration of early eocrinoids.HU ShiXue LUO HuiLin HOU ShuGuang Bernd-Dietrich ERDTMANN 2007Chinese Science Bulletin2007,52,5:13
3云南武定早寒武世关山动物群棘皮动物化石显示文摘报道了云南早寒武世乌龙箐组关山动物群中新发现的始海百合类棘皮动物化石.关山动物群始海百合是目前所发现的最早的始海百合类之一,具腕、萼和柄,其萼板形态简单,无缝孔和瘤突,腕长,呈旋卷状,柄较长,柄与萼的长度之比较大.关山动物群始海百合类棘皮动物的发现,不仅对研究棘皮动物的早期演化提供了新的线索和材料,而且对研究早期棘皮动物和始海百合类生态习性变迁也有着重要的意义.胡世学 罗惠麟 侯蜀光 Bernd-Dietrich Erdtmann 2006科学通报2006,51,11:4
4Graptolite, Chitinozoan and Scolecodont Reflectances and Their Use as Indicators of Thermal Maturity显示文摘Based on studies of the reflectance of Ordovician and Silurian zooclasts from 11 sections around the Huangling Anticline, Hubei, China, combined with determination of the conodont colour alteration indices (CAI) and of infrared spectroscopy of dispersed organic matter from the same or adjacent horizons, it is further proved that reflectances of graptolites, chitinozoans and scolecldonts, like vitrinite and natural bitumen, increase with increasing maturation, but follow different reflectance paths. They may be used, therefore, as thermal maturation indicators. Graptolites display optically strong anisotropy. The maximum reflectance measured from graptolite on polished section cut parallel to the bedding plane is the most suitable for determination of maturation of their host rocks. In polished section chitinozoan and scolecodont show reflectance, but no bireflectance owing to their isotropy. The random reflectance of chitinozoans is higher than that of scolecodonts in the case of the same maturity. By analysing the distribution trends of graptolite, chitionzoan and scolecodont reflectances, the Ordovician and Silurian strata can be subdivided into three areas of maturation in the present region. The potential of oil or gas generation is discussed for each area. The result is basically coincident with the distribution pattern of regional organic maturation presented by CAI and infrared spectroscopic determination of organic matter.Andreas Hoffknecht Rainer Bainer Brocke Bernd-D.

5Succession and global correlation of Late Tremadoc graptolite zones from South China显示文摘The Tremadocian is the first stage of the Ordovician System and is subdivided into two parts in general. The Upper Tremadocian, spanning a temporal interval of ca. 8 Ma, yields graptolite faunas crucial for biostratigraphic division and correlation in high resolution. Relatively complete successions of Upper Tremadoc graptolite zones have been proposed in Scandinavia, and North and South America. In South China, the coeval graptolite strata are widespread in deep water facies, but the successions of grapto- lite zones recognized so far are quite incomplete and thus very difficult to be correlated with those in other countries. In recent years, we have sampled bed by bed the Nanba section in the Yiyang area, Hunan Province and, below the Tetragraptus approximatus Zone, identified four Upper Tremadoc graptolite zones in descending order: the Hunnegraptus copiosus Zone, the Araneograptus murrayi Zone, the Aorograptus victoriae Zone and the Adelograptus tenellus Zone. To date, the Nanba section is the only section in China that presents a relatively complete and globally comparable succession of Upper Tremadoc graptolite zones. Therefore, this study not only confirms the existence of some Upper Tremadoc graptolite zones that were never found before in China, but also facilitates a highly resolved division and correlation for the Upper Tremadoc graptolite strata in China.Bernd-D.
