Download or read book Stratigraphy and Conodonts of Upper Silurian and Lower Devonian Rocks in the Environs of the Boothia Uplift Canadian Arctic Archipelago written by R. 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 1991 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen chapters discuss regional stratigraphy by time intervals from Precambrian to Quaternary, while other chapters describe the geography, geomorphology, tectonics, geophysical characteristics, and resources of the region. A summary chapter includes geologic maps, structural cross-sections, a geotectonic correlation chart, a gravity map, and a location map for exploration wells in the Arctic Islands and northern Greenland. A wealth of additional information is contained on the nine accompanying plates.

Download or read book Biostratigraphy and Conodont Faunas of Upper Ordovician Through Middle Devonian Rocks Eastern Arctic Archipelago written by Teruya Uyeno and published by Geological Survey of Canada. 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." --

Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.
