Sea-level constitutes a critical planetary boundary for geological processes and human life. Sea-level fluctuations during major greenhouse phases are still enigmatic and strongly discussed in terms of changing climate systems. The geological record of the Cretaceous greenhouse period provides a deep-time view on greenhouse-phase Earthsystem processes that facilitates a much better understanding of the causes and consequences of global, geologically short-term, sea-level changes. In particualr, Cretaceous hothouse periods can serve as a laboratory to better understand a near-future greenhouse Earth. This volume presents high-resolution sea-level records from globally distributed sedimentary archives of the Cretaceous involving a large group of scientists from the International Geoscience Programme IGCP 609. Marine to non-marine sedimentary successions were analysed for revised age constraints, the correlation of global palaeoclimate shifts and sea-level changes, tested for climate-driven cyclicities, and correlated within a high-resolution stratigraphic framework of the Geological Timescale. For hothouse periods, the hypothesis of significant global groundwater-related sea-level change, i.e. aquifer-eustasy as a major process, is reviewed and substantiated.
Published between 1850 and 1886, these six volumes by Thomas Davidson offered a definitive reference text on brachiopods.
The thirty papers in this 1986 volume review the scientific knowledge of the nature of flint and chert at this time. These papers were presented at a 1983 interdisciplinary and international conference on flint and other cherts. Each contribution has been meticulously assessed and edited prior to publication. This collection is principally concerned with the geology and geochemistry of flint in European chert. Topics include the origin of flint; scanning electron microscopy of surface textures; and the behaviour of flint under periglacial conditions. There is a companion volume, edited by G. de G. Sieveking and M. B. Hart, on the archaeological uses of flint.
