This book was released on 2016-10-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.

Thorsteinsson and published by Geological Survey of Canada. This book was released on 1980 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Boothia Uplift is a major structural feature that extends north from Boothia Peninsula to the northwestern extremity of Devon Island. On Somerset Island and Boothia Peninsula it consists of Precambrian crystalline rocks and Proterozoic sediments that are flanked by Cambrian to Lower Devonian platform-type sedimentary rocks. This report deals with strata of Late Silurian to Early Devonian age, the time of the principal crustal movements that produced the Uplift." --

This book was released on 1990 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The lower and middle Paleozoic strata of the eastern Arctic Archipelago change rapidly laterally from thin, shallow-water platform deposits to thicker, deeper water basinal deposits. The difficulty in correlating such strata has been overcome in part through well controlled conodont zonation, and by supplementary dating using palynomorphs and megafaunas. Such precise dating and correlation are essential for success in the search for petroleum and other mineral deposits. The study will also help refine calibration of the geological time scale in other parts of the world." --

Book excerpt: "The results of this study allow more precise correlations to be made with the classic Lower Silurian rocks of the Welsh Borderland in Great Britain, and will also facilitate making closer correlations between strata of this age in other sedimentary basins in Canada and elsewhere. Accurate dating of rocks is of great importance in assessing the hydrocarbon and other mineral potential of sedimentary basins." --

This book was released on 1976 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silurian and Devonian rocks are exposed for approximately 8 square kilometers inthe KootenayArc structural province of northeastem Washington. These Middle Paleozoic rocks overlie the Upper Cambrian Metaline Limestone and the Ordovician Ledbetter Formation, which includes slates, siltstones, and limestones. Two Silurian units crop out in this area. Unit A is composed of Lower Silurian graptolitic argillites and siltstones and Upper Silurian siltstones and fossiliferous limestone. These lithologies represent a trend towards shallower water conditions than those operative during deposition of the Ledbetter Formation. Above Unit A lies the quartz granule conglomerate Unit. This unit consists of a silica rich granule conglomerate with associated beds of slate and is interpreted as an inner submarine fan deposit. Devonian rocks are found locally at Limestone Hill. The polymictic Givetian limestone conglomerate crops out at the base of the bill. This conglomerate contains limestone clasts of Lower and lower Middle Devonian rocks, thereby documenting a break in the sedimentary record. The Givetian limestone occurs as float fragments of dark-gray limestone, which preserve a diverse conodont fauna. On the crest of Limestone Hill lies the Frasnian massive and bedded lime stones, which are believed to represent a reef build-up. The post-Paleozoic sedimentary record consists of Quaternary glacial deposits. An olivine trachybasalt of probable Tertiary age crops out for a short distance in the central portion of the map area. The region has undergone several periods of deformation of probable Mesozoic age. The structure is dominated by northeast and northerly trending folds, and northeast and northerly trending steeply dipping normal faults.
