Download or read book Stratigraphy of the Silurian and Devonian Rocks Northwestern Pend Oreille County Washington written by Celia Greenman and published by . 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.

This book was released on 2012-12-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 22 (thesis year 1977) a total of 10,658 theses titles from 28 Canadian and 227 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 22 reports theses submitted in 1977, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Download or read book The Terrane Puzzle written by Robert B. Blodgett and published by Geological Society of America. This book was released on 2008 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Displaced or tectonostratigraphic terranes comprise a huge portion of real estate in the North American Cordillera. Terranes are discrete, fault-bound blocks of regional extent, with rocks and fossils that differ to a great extent from those of adjacent blocks. The allochthonous nature of most terranes, relative to adjacent craton, is well established. When mapped, they resemble a collage of mixed rock types, tectonic styles, metamorphism, and volcanic origins--each part resembling the pieces of a puzzle. Terrane studies remain integral to understanding the geological evolution of western North America. Since the initiation of the concept summarized in 1979 by the late David L. Jones, the significance of fossils and stratigraphy has been key to solving the puzzle. Chapters of this book written by experts in their field, provide a sense of the diversity of approaches in paleontology and stratigraphy. Contributions span geologic time from the Precambrian (Vendian) to Cretaceous and address over 20 Cordilleran terranes."--Publisher's website.
