This book was released on 1989-12-07 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the second of four reference volumes which collectively describe the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the Project's existence. Volume 2 contains 93 chapters contributed by 111 researchers, dealing with most, if not all, of the major individual deposits or phosphate fields of the world, whether of igneous or sedimentary origin. Total resources of phosphate rock are extremely large, but are unequally distributed geographically and only a relatively small proportion can be mined on an economic scale at present. The text is arranged on a continental basis, with an introductory chapter for each continent summarising the distribution of resources within the geological timescale. This unique volume provides a good understanding of the mode of occurrence, geological setting and phosphogenesis of the world's phosphate resources. It forms an invaluable aid to the search for, and exploitation of, phosphate deposits in many countries.

This book was released on 1990-05-10 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the environmental setting and resulting phosphorites that formed during the Miocene, one of the major and most recent phosphogenic periods throughout the geological record. Sedimentary phosphate deposits (phosphorites) are of major commercial significance, being one of the world's most important non-renewable resources, and essential in the manufacture of phosphate fertilizers and phosphate based chemicals. An oceanographic perspective is provided 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 is the third of four planned reference volumes that together will cover the achievements of the International Geological Correlation Programme Project 156 (Phosphates) during the ten years of the project's existence. As with the previous volumes, this will form an essential work of reference for geologists and mining engineers interested in the search for, and exploitation of, phosphate rock deposits.

This book was released on 1986 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of marine phosphorites, the principal raw material for phosphatic fertilizers, 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 period, and investigations of modern oceanic environments where phosphorites are presently forming are also described.
Download or read book Phosphate Deposits of the World Volume 1 written by P. J. Cook and published by Cambridge University Press. This book was released on 1986-09-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique survey describes the world's ancient phosphorite deposits on a scale never previously attempted. The International Geological Correlation Programme started Project 156, on world phosphate resources, in 1977. An international team of forty-six researchers describes in twenty-five chapters almost 100 Precambrian or Cambrian deposits of phosphate rock, extending through all continents except Antarctica. The total resources are large, but only a small fraction is minable at present. The data presented give a good understanding of the distribution, nature and origin of phosphate deposits. The book is an important contribution to the scientific understanding of phosphate deposits, as well as a valuable aid to the search for an exploitation of phosphates in many parts of the world.

This book was released on 2012-09-28 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth’s present-day environments are the outcome of a 4.5 billion year period of evolution reflecting the interaction of global-scale geological and biological processes. Punctuating that evolution were several extraordinary events and episodes that perturbed the entire Earth system and led to the creation of new environmental conditions, sometimes even to fundamental changes in how planet Earth operated. Volume 3: Global Events and the Fennoscandian Arctic Russia - Drilling Earth Project represents another kind of illustrated journey through the early Palaeoproterozoic, provided by syntheses, reviews and summaries of the current state of our understanding of a series of global events that resulted in a fundamental change of the Earth System from an anoxic to an oxic state. The book discusses traces of life, possible causes for the Huronian-age glaciations, addresses radical changes in carbon, sulphur and phosphorus cycles during the Palaeoproterozoic, and provides a comprehensive description and a rich photo-documentation of the early Palaeoproterozoic supergiant, petrified oil-field. Terrestrial environments are characterised through a critical review of available data on weathered and calichified surfaces and travertine deposits. Potential implementation of Ca, Mg, Sr, Fe, Mo, U and Re-Os isotope systems for deciphering Palaeoproterozoic seawater chemistry and a change in the redox-state of water and sedimentary columns are discussed. The volume considers in detail the definition of the oxic atmosphere, possible causes for the oxygen rise, and considers the oxidation of terrestrial environment not as a single event, but a slow-motion process lasting over hundreds of millions of years. Finally, the book provides a roadmap as to how the FAR-DEEP cores may facilitate future interesting science and provide a new foundation for education in earth-science community. Welcome to the illustrative journey through one of the most exciting periods of planet Earth!

This book was released on 2022-01-25 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is primarily the uppermost important sector in Sudan, contributing significantly to the country’s national economy. However, in spite of the country’s vast cultivated area, productivity remains very low. The declining agricultural production is indicative of the need for adopting sustainable agricultural development approaches to the achieve country’s food security. The attainment of sustainable agricultural production will require the proper use of all available resources such as land, water, and mineral resources, including the phosphate rock reserves. Rock phosphate deposits of potential economic value occur at more than a hundred locations in sub-Saharan African countries, including Sudan. Several geological surveys in Sudan have proven the occurrence of abundant resources of phosphate deposits in different locations in the country. For advocating the initiation of rock phosphate mining and phosphate fertilizer industry in Sudan, this book delivers sufficient and validated information on the underutilized resource of rock phosphate in Sudan and exposes its potential role in the development of sustainable agricultural production. The book presents an accurate image of the current status and prospective scenario in relation to rock phosphate deposits and the potential establishment of the fertilizer industry in Sudan. The book presents a comprehensive literature review on the history, advantages, and impacts of using rock phosphate. It also sheds light on the rock phosphate deposits in Sudan, their locations, and geological and agricultural quality as compared to rock phosphate from other global resources. The book presents two detailed case studies on assessing the agronomic value of Kurun and Uro rock phosphate rocks as fertilizers and their environmental impact assessment. The book then highlights the potential benefits of phosphate mining and the initiation of the phosphate fertilizer industry in Sudan, proposes a plan for achieving that goal, and presents recommendations to bring the Sudanese phosphate fertilizer industry to life.
