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.

Download or read book Alaska Dinosaurs written by Anthony R. Fiorillo and published by CRC Press. This book was released on 2018-01-02 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.

Download or read book Dinosaurs Under the Aurora written by Roland A. Gangloff and published by Indiana University Press. This book was released on 2012-07-10 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1961, while mapping rock exposures along the Colville River in Alaska, an oil company geologist would unknowingly find the evidence for a startling discovery. Long before the North Slope of Alaska was being exploited for its petroleum resources it was a place where dinosaurs roamed. Dinosaurs under the Aurora immerses readers in the challenges, stark beauty, and hard-earned rewards of conducting paleontological field work in the Arctic. Roland A. Gangloff recounts the significant discoveries of field and museum research on Arctic dinosaurs, most notably of the last 25 years when the remarkable record of dinosaurs from Alaska was compiled. This research has changed the way we think about dinosaurs and their world. Examining long-standing controversies, such as the end-Cretaceous extinction of dinosaurs and whether dinosaurs were residents or just seasonal visitors to polar latitudes, Gangloff takes readers on a delightful and instructive journey into the world of paleontology as it is conducted in the land under the aurora.

Available in PDF, EPUB and Kindle. Book excerpt: Isotopic studies combined with geochemical, lithological, mineralogical and palaeontological investigations have been widely used in reconstructing Cretaceous marine and continental environments. Furthermore stable and radiogenic isotope trends play an important role in the interpretation of the causes and consequences of biotic turnovers at stratigraphic boundaries as well as in global correlations.
