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.

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.

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!

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.

The combined efforts of the World Peace Foundation, the G. D. Howe Research Institute, and the Centre Quebecois de Relations Internationales have culminated in a comprehensive three-volume study of critical U.S.-Canadian resource issues. Motivated initially by the tensions of the mid-1970s and by immediate U.S. concerns about the actions of its maj
