Silurian Lands and Seas is the only up-to-date synthesis of plate tectonics, paleogeography, biotic distribution, and geologic history of the 20 million year-long Silurian geologic period. In-depth contributions by 44 specialists recreate the geologic history of this important interval in earth history in eleven important regions : $ (ca. – Ma). However, Western Gondwana, of which present-day Brazil occupies a part, was undergoing an ero-sional phase during Triassic-Jurassic time ( – Ma). The sediments deposited in these periods were accordingly of continental (non-marine) derivation, some even subaer-ial (non-aqueous, mostly eolian).
The Paleogeographic Evolution of the Arctic and North Atlantic Oceans during the Cretaceous. Paul Markwick, Stanislaw Mazur, Rkia Bouatmani, Andrew Quallington, Daniel Campanile, Amanda Galsworthy, Lauren Raynham, Melise Harland, Kate Benny, Rob Bailiff, Kathelijne Bonne, Laura Hagen, and Dorothea Eue GETECH, Leeds, United Kingdom.. The Arctic Ocean was a largely geographically . Western Canada during the Mesozoic The Mesozoic extends over million years from the beginning of the Triassic ( Ma) to the end of the Cretaceous (65 Ma). It was a particularly important period for the geology of western : Steven Earle.
Marine sedimentation continued until the Campanian - early Maastrichtian, when widespread erosion led to the non-preservation of the upper portion of the Cretaceous marine sequence. Coarse-grained deposits of this age unconformably overlie marine shales along the western border of the UMV Basin, suggesting a rapid uplift of the Central Cordillera. associated with the High Arctic Large Igneous Province (HALIP). The uplift of the source area, and the corresponding change in the regional paleogeography, appears to have started some time before the main magmatic event dated to Ma. The regional uplift in the north imposed a north-south tilt of the entire Barents Shelf, including Svalbard.

The climate was also more equable in that the temperature difference between the poles and the Equator was about one-half that of the present.
