Sedimentary rocks are created by the deposition or accumulation of material, organic particles, or minerals in bodies of water and formed at the Earth's surface. Sedimentation is the name given to the formation of these rocks. Limestone, dolostone, clay, sandstone, sandstone, and shale are some common sedimentary rocks formed out of the sedimentation and cementation processes that cause these particles, which can be coarse, medium, or fine-grained or stratified according to their conditions of formation. The first section of this book discusses different aspects of sedimentary rocks. Aquifers are vital resources of freshwater in many countries. However, such groundwater resources are limited, scarce, and unevenly distributed over the Earth's surface. The second section of this book discusses the basaltic aquifer and aquifers in South Africa.

"The study of sediments and sedimentary rocks continues to be a core topic in the Earth Sciences and this book provides the reader with a concise account of their composition, mineralogy, textures, structures, diagenesis and depositional environments. The earlier editions of this book have been used by successive generations of students for more than 40 years, and it is the standard text on the subject in many universities throughout the world. This fourth edition is a comprehensive update and expansion of the previous editions with substantially updated new references and suggestions for further reading. The new co-author Stuart Jones has brought his expertise in clastic sedimentology to the rewritten chapters on sandstones and mudrocks. The addition of color images throughout the text enhances the book immeasurably and will aid the student in petrographic work" --

Phosphate Rock: An Industry in Transition takes an interdisciplinary approach to dealing with the phosphate rock chain and its exploration, extraction, processing, fertilizer making, and storage and transportation. The book treats the subject from a global perspective, giving readers insights into what is happening in the emerging economies of the world and possible solutions to problems. It also provides all the parameters necessary to evaluate economic viability of undertaking a mining venture, taking into consideration demands of sustainable mining - social responsibly, environmental pollution control measures, community development, and precautions necessary for ensuring health and safety in the hazardous conditions of mining operations. In recent years, supply chain management has grown in importance as it forms tighter links in integration of key business processes from initial extraction of raw phosphate rock to end customers through different stages of process techniques. The book surveys the changes in technology, including many game-changing innovations that could transform mining. Presents a purposive classification of resources, status of global phosphate rock reserves, and their life-indices Covers mining conditions and possibilities of improvement in methods of exploration and environmental impact Includes economic considerations for resource assessment, mining, quality control and supply problems.
