This book examines and summarizes data on more than 40,000 diamonds from deposits in Russia’s diamondiferous Arkhangelsk province. The geological data of diamond deposits includes the geological setting, ore body morphology and mineral composition. Investigation techniques employed include: Color Cathode Luminescence, Fourier Transform Infrared Spectroscopy, Electron Paramagnetic Resonance, Raman Spectroscopy, and Carbon Isotopy. The book provides a full description of the diamond morphology. The problems of a potential (mantle) diamond grade for deposits are considered, depending on the physical and chemical conditions involved in the genesis and growth of diamond crystals. Further, there can be a significant impact on the productivity of bodies and the properties of diamonds during post-crystallization metasomatic processes. In this book, the authors propose a diamond crystallization model for changes in diamond crystals within mantle metasomatic transformations, and identify the factors affecting the growth and dissolution of diamonds in the mantle. In addition, they describe the complex evolution of kimberlite from the mantle up to the Earth’s surface. All of these factors affect the quality and quantity of diamonds in a particular diamond deposit, providing the basis for identifying optimal technological mining processes.

This proceedings book represents a collection of conference papers examining the fundamental problems of deep magmatism.Enriched mantle reservoirs can be the source of the most massive apatite and rare metal deposits. Additionally, this book also presents some of the characteristics of kimberlites' composition from the deep Yubileinaya pipe and the mineralogical features of the Nakyn kimberlite field (Yakutia) and the crystallochemical features of rare and complex silicates from charoite rocks of the deep Murunskii massif in South Africa and the comendites of Mongolia.

This edited book gives a general overview on current research, focusing on geoenvironmental issues and challenges in hydrogeosciences in model regions in Asia, Europe, and America, with a focus on the Middle East and Mediterranean region and surrounding areas. This proceedings book is based on the accepted papers for oral/poster presentations at the 2nd Springer Conference of the Arabian Journal of Geosciences (CAJG-2), Tunisia 2019. It offers a broad range of recent studies that discuss the latest advances in geoenvironmental and hydrogeosciences from diverse backgrounds including climate change, geoecology, biogeochemistry, water resources management, and environmental monitoring and assessment. It shares insights on how the understanding of ecological, climatological, oceanic and hydrological processes is the key for improving practices in environment management, including the eco-responsibility, scientific integrity, and social and ethical dimensions. It is of interest to scientists, engineers, practitioners, and policymakers in the field of environmental sciences including climatology, oceanography, ecology, biogeochemistry, environmental management, hydrology, hydrogeology, and geosciences in general. In particular, this book is of great value to students and environment-related professionals for further investigations on the state of Earth systems.

Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.

A sweeping history of our enduring passion for diamonds—and the exploitative industry that fuels it. Blood, Sweat and Earth is a hard-hitting historical exposé of the diamond industry, focusing on the exploitation of workers and the environment, the monopolization of uncut diamonds, and how little this has changed over time. It describes the use of forced labor and political oppression by Indian sultans, Portuguese colonizers in Brazil, and Western industrialists in many parts of Africa—as well as the hoarding of diamonds to maintain high prices, from the English East India Company to De Beers. While recent discoveries of diamond deposits in Siberia, Canada, and Australia have brought an end to monopolization, the book shows that advances in the production of synthetic diamonds have not yet been able to eradicate the exploitation caused by the world’s unquenchable thirst for sparkle.

The book summarizes the author's experimental studies of phase relations in the chemical systems relevant to Earth, carried out in a time period of over 20 years using piston-cylinder and multi-avil presses. A summary of the research at high pressures and temperatures carried out by many other experimental petrologists is also included. The data was used to develop an internally consistent thermodynamic model, which was then used to calculate phase diagrams. This produced the largest collection of the calculated phase diagrams published so far, encompassing for the first time the temperature and pressure ranges corresponding to the whole upper mantle.
