About the book
Sand is characterized mainly by any grain that is 0.0625 mm to 2 mm in size. Sandstone is a clastic sedimentary rock composed of sand-sized mineral grains, rock fragments or pieces of organic materials forming a solid rock. While sediment and sedimentary rocks make up only a small percentage of Earth?s crust, they form a thin layer of rock over 75 percent of the Earth's surface. More than 90% of all sedimentary rocks consist of sandstones, mudrocks, carbonate rocks. However, sandstone has an important abundance in all of the sedimentary rocks. Therefore, sandstone is a widespread and well-known sedimentary rock and is found in sedimentary basins throughout the world. It is formed in a wide range of environments and occurs in strata of all geologic ages. Most significantly, they are useful sedimentary rock types for deciphering Earth history. On the other hand, the study of sedimentary rocks has economic significance as sources of petroleum products, water, building materials, and metallic ores such as uranium minerals, heavy minerals such as rutile, gold, diamonds, and others that can be found in sandstones from prehistoric placer deposits.
The overall aim of producing this book is to present the latest high-quality researches on the sand and sandstones from various parts of the World. Chapters investigating sand and sandstones in terms of different aspects will be included in the book. We believe that this book will be of great value for students and professional geologists.
