Download or read book Description and Interpretation of the Jurassic J-2 Unconformity of the Western Interior (U.S.A.) written by Christopher Swezey and published by . This book was released on 1991 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Jurassic J-2 surface is one of the more extensive unconformities of the Western Interior (U.S.A.). Stratigraphic relationships show that this is an angular unconformity, which developed first in the north and progressively moved south. An examination of features associated with the J-2 surface reveals detrital and diagenetic chert grains, ventifacts, polygonal fracture patterns, oscillation ripples, and paleotopographic relief. Some of these features indicate that the J-2 unconformity was a hot, dry, deflationary surface, and that the level of deflation on this surface was controlled, at times, by the height of the water table. The ventifacts are a lag deposit of the overlying Gypsum Spring Formation. Three possible variables involved in the formation of the J-2 surface are fluctuations in water table, disruption of sediment supply, and tectonic activity. For the Early-Middle Jurassic, these variables can be associated with increased rifting rates in the Atlantic Ocean. The increase in rifting rate raised eustatic sea level, which resulted in a larger area for deposition of marine sediments and a rise in continental water table. A higher water table would have trapped sediment that was previously available for sand sea (erg) formation. Furthermore, a higher sea level might have changed sediment supply and transportation routes. As the increase in rifting continued, tectonic movement and tilting of the North American plate occurred. This tilting caused the uplift and erosion of some deposits, and influenced the sites available for sediment preservation.

Book Synopsis Regional Stratigraphy of North America by : W.J. Frazier
Download or read book Regional Stratigraphy of North America written by W.J. Frazier and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: An early reviewer of this book stated that he had difficulty assessing its marketability because it "falls between the cracks" of geological literature. We have designed this book to meet a need of modem geology: namely, a single source providing both detailed and synoptic stratigraphy of the various regions of North America, through geological time. Shortly after beginning work on such a book, we realized why it had not yet been written: it required six years of effort, assimilation of an incredible amount of information, and two years' additional work to cut the volume down to publishable size. Further, by the time the final chapter was written, the fIrst few were already out of date. Nevertheless, the book lies in front of you. It is intended to serve several purposes. As a textbook, it will serve the following courses: • Regional stratigraphy • Sedimentary tectonics • Regional tectonics • Advanced historical geology • Survey-level paleontology Obviously, not all portions of the book are relevant to all of the above courses. We assume the reader will retain this book after the particular course is done, and will use it as a reference book. Hopefully, others will obtain the book solely for reference purposes. We believe it will be especially useful for the working geologist or academic geologist seeking generalized and some moderately detailed information about a region or geological time interval which is unfamiliar.
