中文摘要
Cenomanian / Turanian(C / T)边界间隔,其全球特征是黑色页岩(OAE 2)的沉积,已经研究了20多年。目前,我们为OOP Leg 207的OAE 2编制了一个高分辨率的5l 3Corg数据集,以便将这些黑色页岩与其他地方的记录相关联。然而,高分辨率的古温度和碳同位素记录受到地层控制差的影响。因此,我们寻找一个网站,使我们能够建立一个地层参考部分的OAE 2,包括数据从微体古生物学,宏观古生物学和稳定同位素。这将通过在德国温斯托夫对OAE 2的独特和扩展继承进行取芯来实现。文斯托夫剖面是世界上最大的、最容易进入的森诺曼中期到图兰早期的连续地层之一,具有厚厚的黑色页岩。从附近的采石场了解到的大量保存完好的宏化石和微体化石,将使我们能够为C / T边界层段建立一个高分辨率的化学和生物地层学,这将成为国际标准。一个高分辨率的同位素地层对比腿207孔和文斯托夫节也将使我们能够了解在腿207所观察到的古海洋学变化的精确时间。
英文摘要
The Cenomanian / Turanian (C / T) boundary interval, which is globally characterised by the deposition of black shales (OAE 2), has been studied for more than 20 years. Currently we compile a high-resolution 5l3Corg dataset for the OAE 2 of OOP Leg 207 in order to correlate these black shales to records elsewhere. The high resolution palaeotemperature and carbon isotope records suffer, however, from a poor stratigraphic control. We therefore look for a site which allows us to establish a stratigraphic reference section of the OAE 2, including data from micropalaeontology, macropalaeontology and stable isotopes. This will be achieved by coring a unique and expanded succession of the OAE 2 at Wunstorf, Germany. The Wunstorf section comprises one of the world s most expanded, accessible middle Cenomanian to early Turanian successions with thick black shales. Abundant and welt preserved macro- and microfossils, known from the near by quarry, will enable us to develop a high resolution chemo- and biostratigraphy for the C / T boundary interval which will serve as an international standard. A high-resolution isotope-stratigraphic correlation of Leg 207 holes and the Wunstorf section will also enable us to understand the precise timing of the observed paleoceanographic changes at Leg 207.
