Download or read book Phosphate Deposits of the World Volume 3 Neogene to Modern Phosphorites written by P. J. Cook and published by Cambridge University Press. This book was released on 1986 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine phosphorites, the principal raw material for phosphatic fertilizers, do not occur uniformly through time and space. The origin of these unusual sedimentary rocks appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene, one of the major and most recent phosphogenic periods throughout the geologic record. In addition, an oceanographic perspective is given by investigations of modern oceanic environments where phosphorites are presently forming. Together, the geologic and marine approaches provide a complete outlook on this important mineral resource. This book is the third of four reference volumes which together cover the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the project's existence.
Download or read book Evolution and Environment in Tropical America written by Jeremy B. C. Jackson and published by University of Chicago Press. This book was released on 1996-12-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: How were the tropical Americas formed? This ambitious volume draws on extensive, multidisciplinary research to develop new views of the geological formation of the isthmus linking North and South America and of the major environmental changes that reshaped the Neotropics to create its present-day marine and terrestrial ecosystems. Recent discoveries show that dramatic changes in climate and ocean circulation can occur very quickly, and that ecological communities respond just as rapidly. Abrupt changes in the composition of fossil assemblages, formerly dismissed as artifacts of a poor fossil record, now are seen as accurate records of swift changes in the composition of ocean communities. The twenty-four contributors use current work in paleontology, geology, oceanography, anthropology, ecology, and evolution to paint this challenging portrait of rapid environmental and evolutionary change. Their conclusions argue for a revision of existing interpretations of the fossil record and the processes—including invading Eurasian peoples—that have produced it.
Download or read book Taxonomic Revision and Phylogenetic Analysis of the Flightless Mancallinae Aves Pan Alcidae written by N. Adam Smith and published by PenSoft Publishers LTD. This book was released on 2011-04-20 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flightless Mancallinae (Aves, Pan-Alcidae) from the Pacific Ocean are represented by one of the richest fossil records among Charadriiformes. A detailed review of previously published and previously undescribed fossils referred to Mancallinae resulted in taxonomic revision of the clade and the identification of three new species from the Miocene and Pliocene of California, USA. This monograph includes descriptions of new Mancallinae species and provides the first species-level phylogenetic hypothesis of Mancallinae relationships. Phylogenetic hypotheses were generated through the combined analysis of molecular sequence data and newly identified morphological character data for extant and extinct charadriiforms. The results of the combined phylogenetic analysis places hypotheses regarding the ethology and morphological convergence of Mancallinae to other flightless wing-propelled divers in phylogenetic context and facilitates comparisons between alcid paleodiversity and paleoclimatic events that have been hypothesized as drivers of alcid evolution.

Download or read book Biology of the Hard Clam written by J.N. Kraeuter and published by Elsevier. This book was released on 2001-04-26 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hard clam, Mercenaria mercenaria, is an important commercial, recreational and ecological inhabitant of coastal bays along the east and gulf coasts of the United States. This title represents the first state of the art summary of existing knowledge of the hard clam by experts in various disciplines.Containing a compendium of literature on the hard clam, comprehensive chapters on various aspects of its biology as well as summaries of knowledge including the gray literature on this economically important species, this volume represents a comprehensive source of biological information for managers and researchers interested in shallow marine and estuarine ecosystems. Research students and managers charged with maintaining coastal ecosystems will also find a wealth of background material.The first synthesis of available information on the mercenaria mercenaria, this title is a response to the needs of individuals involved in hard clam aquaculture and scientists interested in molluscan biology, coastal ocean ecology and similar fields. Over 2300 documents have been synthesized, and chapter authors have added unpublished information as well as new material.
Download or read book The Chesapeake Bay Crater written by Wylie Poag and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have synthesized 16 years of geological and geophysical studies which document an 85-km-wide impact crater buried 500 m beneath Chesapeake Bay in south eastern Virginia, USA. In doing so, they have integrated extensive seismic reflection profiling and deep core drilling to analyze the structure, morphology, gravimetrics, sedimentology, petrology, geochemistry, and paleontology of this submarine structure. Of special interest are a detailed comparison with other terrestrial and extraterrestrial craters, as well as a conceptual model and computer simulation of the impact. The extensive illustrations encompass more than 150 line drawings and core photographs.
