The Permian was a remarkable time period. It represents the maximum stage of Pangean continental assembly, includes a major global climatic shift from glacial to nonglacial conditions (icehouse-greenhouse transition), and is ter minated by one of the most profound faunal/floral extinction events in the Earth's history. In addition, Permian oceans, although poorly understood, must have had some quite unique characteristics. Permian seas reached the most extreme values of carbon, sulfur, and strontium isotopic ratios ever achieved in Phanerozoic time, and the isotopic ratios of all three elements abruptly returned to more "normal" values at, or very close to, the Permo Triassic boundary. Finally, the Permian is marked by an abundance of important sedimentary mineral resources. It has large fossil fuel concentra tions (coal, oil, and natural gas), enormous phosphate reserves, and very extensive evaporite deposits, including gypsum, anhydrite, and halite, as well as a variety of potash salts. Study of the Permian has been hampered, however, by a number of factors. These include a scattered geologic literature (presented in a variety of languages), a confusing regional and global stratigraphic framework (based, in part, on inadequate type sections), and largely provincial, often poorly correlatable faunas. All have contributed to the sparsity and inadequacy of overviews of this critical geological interval. The two volumes attempts to bring together some of the widely scattered observations about these fascinating rocks, at least for the northern (pre dominantly nonglacial) parts of Pangea.

Modeled after the 1961 ground-breaking book The Genesis Flood by Drs. Whitcomb and Morris, this detailed work builds on that classic volume with new insights from decades of work by the author, Dr. Andrew Snelling, and numerous colleagues. This recent revolution in geology and the explosion in geological research have established an even firmer basis for understanding the biblical Flood with a God-honoring foundation — the absolute authority and inerrancy of God’s Word. Examine details of the Creation Week as it builds a solid scriptural case for the Flood’s catastrophic nature and global extent. Find decisive answers to many questions about the Flood and Noah’s Ark, its construction, and the animals taken onboard. Delve deeply into astonishing geological details that unfold from the early chapters of Genesis, including the Creation Week and the pre-Flood world. Explore detailed evidence and a concise, informative 30-page color section with diagrams, maps, and more! Dr. Snelling jettisons the faulty evolutionary-uniformitarian assumptions used by most geologists and instead, interprets compelling new geological and observed field data within the biblical framework for the earth’s history. He also demonstrates that fossils were catastrophically buried in sedimentary layers being deposited rapidly on a global scale on the continental plates derived from the violent rifting apart of the original supercontinent. His work demolishes radiometric dating, the icon of the millions of years dogma, and builds a thoroughly powerful case for a young earth that explains many geological features such as varves, evaporites, coal, oil, chalk, granites, and more that biblical skeptics sadly have used to scoff at God’s Word. Discover the powerful truth behind the earth’s most enduring mysteries!

Explore the early days of Paleoindian archaeology in this engaging retrospective of Edgar B. Howard's Southwest Early Man Project, 1929-1937, cosponsored by the University Museum and the Academy of Natural Sciences of Philadelphia. This book contains a detailed analysis of the world-famous Clovis artifacts, discovered among the bones of mammoths and extinct bison in the Dust Bowl of eastern New Mexico. Blending traditional and current ideas, the authors offer an extended reference to the lifeways of early humans in the Americas, accented by a series of unique insights on their origins and adaptations. Well appointed with photos, line illustrations, and schematics, Clovis Revisited is essential reading for professionals, students, and avocational enthusiasts.

First published in 1988, Castle Gap and the Pecos Frontier was acclaimed by reviewers as “superb,” “significant,” and “utterly delightful.” In this revised edition, Patrick Dearen draws upon the latest in scholarship to update his study of the Pecos River country of West Texas. It’s a land wild with tales that blend history, geography, and folklore, and from his search emerge six fascinating accounts: -Castle Gap, a break in a mesa twelve miles east of the Pecos River, used by Comanches, emigrants, stage drivers, and cattle drovers; -Horsehead Crossing, the most infamous ford of the Old West; -Juan Cordona Lake, a salt lake where sandstorms and skull-baking sun defied early efforts to mine salt vital to survival; -The “bulto” or ghost who wanders the Fort Stockton night; -Lost Wagon Train, a forty-wagon caravan buried in the sands; -The lost mine of Will Sublett, who found gold and kept its location secret unto death. Although linked by the search for treasure, the stories are as varied as the land itself. They speak eloquently of the Pecos country, its heritage, and its people.

Historically, submarine-mass failures or mass-transport deposits have been a focus of increasingly intense investigation by academic institutions particularly during the last decade, though they received much less attention by geoscientists in the energy industry. With recent interest in expanding petroleum exploration and production into deeper water-depths globally and more widespread availability of high-quality data sets, mass-transport deposits are now recognized as a major component of most deep-water settings. This recognition has lead to the realization that many aspects of these deposits are still unknown or poorly understood. This volume contains twenty-three papers that address a number of topics critical to further understanding mass-transport deposits. These topics include general overviews of these deposits, depositional settings on the seafloor and in the near-subsurface interval, geohazard concerns, descriptive outcrops, integrated outcrop and seismic data/seismic forward modeling, petroleum reservoirs, and case studies on several associated topics. This volume will appeal to a broad cross section of geoscientists and geotechnical engineers, who are interested in this rapidly expanding field. The selection of papers in this volume reflects a growing trend towards a more diverse blend of disciplines and topics, covered in the study of mass-transport deposits.
