1全球已批准的和潜在的层型剖面和点位(GSSPs)显示文摘自 1978年确立全球泥盆系底界层型和点位以来 ,国际地层委员会动员全球许多领域的地层学家为地质历史各个断代 (包括界、系、统、阶 )确立底界层型和点位 (俗称“金钉子”)。这在国际地层学发展史上 ,是一个重要的里程碑。尽管在实施原理和方法上还有不同的意见、工作中也出现一些不尽如人意的地方 ,但其功绩 ,特别是在为寻求全球地质学基础的共同语言中所建立的功勋 ,将永载史册。然而 ,当前国际地层委员会已认识到这项工作并不是、也不能代表地层学的全部。从目前情况看 ,在显生宙 13个系内约 10 0个层型剖面和点位中 ,已有 45个被批准确立 ,18个或条件已经成熟或接近完成 ,预计2 0 0 3年将被提出并批准 ;还有约 37个的研究正在进行之中。新生代的大部分完成了 ;中生代 (特别是白垩系和三叠系 )的还有一大半没有定 ,任务不轻 ;古生代的以志留系和泥盆系的确立最早 ,但前者还存在一些问题 ,奥陶系的虽起步不晚 ,但由于种种原因 ,进展稍慢 ,正在加紧进行 ,石炭系和寒武系的也在努力之中。国际地层委员会已经决定这项工作必须在 2 0 0 8年全部完成 ,以利于尽早转入下一个阶段更加深入的、全球地层学各领域的协同研究。J.

2Astronomical time scale for the lower Doushantuo Formation of early Ediacaran,South China显示文摘Nearly 90% of the Ediacaran Period(635–541 Ma) of the Neoproterozoic is represented by the Doushantuo Formation(DST Fm) in South China.Its lowest Member I is a 3.7 m-thick cap carbonate deposited at the termination of the Cryogenian Marinoan glaciation.The DST Fm consists of alternating organic-rich black shale and thinly bedded dolostone, and it contains some of the oldest records of multicellular life and three pronounced negative carbon isotope excursions.The Jiulongwan(JLW) section is a well-studied reference section for these Ediacaran events.Spectral analysis of geochemical data through the lower DST Fm(22.3 m) shows 27 predominant ~90 cm sedimentary cycles that correspond to 405-ka long eccentricity cycles.The power spectra of the 405-ka tuned Ca and Fe/Ti series show significant peaks at ~1.2-Ma, 405-ka, 133-ka, 128-ka, 100-ka, 82-ka, ~31-ka and 29-ka periods, respectively.A 11.16 Malong astronomical time scale has been constructed for the lower DST Fm and provide a duration of 1.6 Ma for the cap carbonate(Member Ⅰ) based on the 405-ka long eccentricity cycle tuning.Using the U-Pb age of 635.2 ± 0.6 Ma for the volcanic ash bed at the Member Ⅰ/Ⅱboundary, we proposed a 636.8 Ma age for the base of the DST Fm.These ages and astronomical timescale provide important new constraints on the subdivision of Ediacaran strata, and have implications for understanding the character of the first negative δ^(13)C excursion(EN1).Orbital forcing may have been played an important role for the climate changes and the evolution of Ediacaran multi-cellular life and the carbon cycle variations.Yu Sui Chunju Huang Rui Zhang Zhixiang Wang James Ogg David B.Kemp 2018Science Bulletin2018,63,22:4
