Increasing population density and industrialization are creating a high strain on the natural environment and resources of many countries. Therefore, precautionary measures to protect the environment and remedial action to repair the damages of the past have high priority. Resources to be protected are surface water and groundwater, soil and air. Hazards to these resources are landfills and industrial sites as well as mining facilities, including tailings, conditioning plants, and smelters, oil refineries, distribution facilities and pipelines, gas stations and other areas used by humans (e.g., military training sites).

Geotechnical failures, specially the catastrophic ones, are an excellent experience and a source of inspiration to improve our current understanding of phenomena and our procedures and tools for analysis and prediction. This unconventional manner to learn Geomechanics is the essence of this book. In general, Soil Mechanics and Geotechnical text books describe first the concepts and the theoretical developments and then apply them to interpret or solve a particular application. This book has a different approach. The case (a failure) is first described and then an explanation is sought. This approach is developed through a set of steps which can be summarized as follows.

Crystal growth of diamonds at the Earth’s mantle depths of 150–800 km had been accompanied by a fragmentary capturing minerals, melts and volatile compounds (as diamond-hosted inclusions) from the parental melts. This indicates convincingly that diamonds were originated jointly with the phases of primary hermetic inclusions in a common parental medium. This opens up possibilities for evaluating the general chemistry of natural diamond-producing systems from the compositions of significantly different phases associated with diamonds in primary inclusions. Of particular value is that it has been made possible to determine the boundary compositions for the experimental systems which duplicate the natural ones responsible for genesis of diamonds and associated phases. As a consequence, the principal problems of diamond genetic mineralogy may be formulated. It became apparent, that the methodology of physico-chemical experiments is of crucial importance in solution of the genetic problems for diamonds and associated phases. <...>

The discovery of electron diffraction in the laboratories of C.J. Davisson and G.P. Thomson in 1927 certainly ranks as one of the monumental discoveries in the history of science. Soon after this invention, it was realised that electrons - like X-rays - are diffracted by the atoms in matter and thus can be used for structure determination. Because the attainable scattered  intensities for electrons are about 106 times larger than for X-rays, electron diffraction allows us to study the interior structure of matter down to a few cubic-nanometers in size. This is far beyond the capabilities of X-ray crystallography or even a modern synchrotron.

Mongolia occupies the central part of the giant Central Asian Orogenic Belt—an accretionary orogen with long-time evolution since the early Palaeozoic to Mesozoic. The orogenic belt formed by accretion of Cambrian, Ordovician and DevonianCarboniferous arcs, back-arcs and accretionary wedges contains world-class copper porphyry, and orogenic gold deposits originated in subduction zones and a number of important deposits related to the post-orogenic and intraplate settings.

The “Supercontinents” constitute the majority of the ancient Earth’s surface and play an important role in Earth’s history (Meert 2012). Supercontinent defined as a large, solid, homogeneous massif of the Earth’s crust, which contains nearly all the continental crust of the planet. It is believed that the largest part of the continental crust formed in the period of 3,200–2,500 million years (Ma) and its fragments are included in all the modern continents (Lubnina and Slabunov 2011).

The Arabian–Nubian Shield (ANS) is a vast and exceptionally well-preserved expanse of crust and underlying sub-continental lithospheric mantle that was largely produced during the Neoproterozoic, with only restricted contribution from older lithospheric components, except in the extreme north-eastern part of the shield. With an exposed area of nearly 2 million km², and an additional 1 million km² buried beneath the great Cenozoic East African Rift System and its associated volcanic rocks, the shield represents one of the best-preserved Neoproterozoic orogenic belts on the planet and the largest preserved expanse of new Neoproterozoic lithosphere in Earth’s geological history.

The passion to understand the Geology of Egypt could be traced back to 1150 BC. In this year, the oldest geological map in the world was prepared to illustrate the geology of the Hammamat-Fawakhir area in the central part of the Eastern Desert of Egypt.

It is necessary to define some fundamental terms that will provide indispensable background for the entire book. The first term to be explained deals with the title of the book: mineral resources. A mineral resource can be defined broadly as the concentration of material of economic interest in or on the Earth’s crust. In this book, it includes solid earth materials such as metals (i.e., copper, gold, iron),

The consumption of primary raw materials has increased ever faster in recent decades, not least due to rapid economic growth in countries such as China, India, and Brazil. Petroleum and natural gas continue to be the most important energy sources driving engines and turbines worldwide, while petroleum is also the most important raw material for the production of plastics, various medicines, and other products of the chemical industry.
