The Permian of Northern Pangea


Book Description

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. These two volumes attempt to bring together some of the widely scattered observations about these fascinating rocks, at least for the northern (predominantly nonglacial) parts of Pangea.




Sedimentary Basins


Book Description

This completely revised and enlarged second edition provides an up-to-date overview of all major topics in sedimentary geology. It is unique in its quantitative approach to denudation-accumulation systems and basin fillings, including dynamic aspects. The relationship between tectonism and basin evolution as well as the concepts of sequence cycle and event stratigraphy in various depositional environments are extensively discussed. Numerous, often composite figures, a well-structured text, brief summaries in boxes, and several examples from all continents make the book an invaluable source of information for students, researchers and professors in academia as well as for professionals in the oil industry.










Sedimentary Environments Offshore Norway-Palaeozoic to Recent


Book Description

Required reading for geologists working in the offshore areas, Volume 10 continues the series from the Norwegian Petroleum Society. This work provides an up-to-date review of the late Palaeozoic to present sedimentary history of the Norwegian offshore areas in the North Sea and Mid-Norway basins. Case studies, overview articles and analogue examples from adjacent areas such as Greenland and Denmark, present new ideas on the development of the Norwegian margin from the Carboniferous through the Mesozoic and Cenozoic.In particular, new evidence and interpretations are presented on well-known major reservoir-bearing successions such as the Statfjord Formation and Dunlin Group in the Northern North Sea, and the Åre and the Tilje Formations in the Mid-Norway area. Furthermore, the Upper Jurassic succession in the Haltenbanken area is described, giving new evidence on the interplay between extensional tectonics and sedimentation during the second major rift phase in the area.The Cretaceous and Cenozoic periods are treated extensively, showing their importance as overall deep water sedimentary systems with proven and potential reservoir rocks, such as in the Ormen Lange Field, and for causing burial of Jurassic rocks to advantageous depths for hydrocarbon generation. The Recent sedimentary history of the Norwegian margin is treated with examples of the glacial history and giant submarine slides which understanding is vital for the placement of offshore installations.The book is organised based on geologic time, from Palaeozoic through Mesozoic to Cenozoic examples. It includes a set of palaeogeographic maps from the Carboniferous through to the Cenozoic. In addition, there are numerous examples of core photographs, well log data, correlation panels and seismic as well as outcrop photographs and logs from the analogue examples. Comprehensive reference and keyword lists are also included.




Mesozoic Resource Potential in the Southern Permian Basin


Book Description

The Southern Permian Basin, as its name suggests, is a historical heartland for hydrocarbon production from the Palaeozoic Rotliegend interval. However, in this mature basin the Mesozoic presents further possibilities to offer resource security to NW Europe. Such opportunities include increasing efficiency in the production of discovered hydrocarbons, exploration for further hydrocarbons (both conventional and unconventional) and efficient exploration for, and production of, geothermal energy. All these potential resources require a grounding in technically sound geoscience, via traditional scientific observation and the application of new technologies, to unlock their value. The main aim of this volume is to bring together the work of academics and industry workers to consider cross-border geoscience including contributions on Poland, Germany, The Netherlands, the United Kingdom and adjacent areas. The work presented intends to contribute to the development and discovery of further Mesozoic energy resources across the basin.




Lower Permian Colonial Rugose Corals, Western and Northwestern Pangaea


Book Description

"The most comprehensive summary available on the stratigraphic occurrence, geographic distribution, phylogeny, and taxonomy of Early Permian colonial rugose corals that occupied the Cordilleran - Arctic - Uralian (CAU) Realm, along the northwestern and western marine shelves and accreted terranes of the ancient supercontinent Pangaea. It is based on all previous studies by other coral specialists, a thorough review of all published data, and on information from a very large number of new collections from new areas. This book contains a new classification and phylogenetic scheme, based on critical restudy of the entire coral fauna at all taxonomic levels."--Publisher's website.




Bryozoan Studies 2004


Book Description

A selection of papers presented at the 13th International Conference of the International Bryozoology Association held in Concepción Chile in January 2004 and hosted by the Universidad de Concepción and Universidad Católica de la Santísima Concepción. The topics presented in this volume reflect the diversity of studies on bryozoa with authors from 18 countries. They include investigations in seven thematic areas: ecology and life strategies; recent and fossil faunas of Australia and New Zealand; past and present bryozoans from both Antarctic and Arctic seas; geology and palaeontology of bryozoans from Eurasia and North America; fresh water bryozoans around the world; fossil bryozoans of the Mediterranean and Tethyan realms and evolution and diversity of recent species. This volume represents the newest advances made in bryozoological studies during the last three years, and makes a significant contribution to the literature.
