Gems have been used in the manufacture of jewellery and as ornaments since antiquity. Considering gems, recent statistics have shown that about 15 billion Euros are annually at stake. Nowadays, gemmology, i.e., the study of gem materials, is one of the most expanding fields in the earth sciences, positioned between academia and industry. As an applied science, in gemmology, the instruments used should be non- or microdestructive, and their cost should be reasonable both in terms of equipment and time consumption. Gemmology can also be used contribute to the development of pure science and in some cases, destructive techniques may have to be used. Taking into account the fact that gems are albeit rarely available for scientific research, this compilation of 20 articles by around 100 researchers from over 30 different institutions situated in 20 countries from around the globe, presented in the Special Issue entitled “Mineralogy and Geochemistry of Gems”, offers very good examples on the application of various methods for their study which will hopefully contribute to our better understanding of gem formation in general and will enhance scientific debates attracting more scientists from various disciplines to get involved in this field.

Due to its stable physical and chemical properties and its abundance in nature, quartz is widely employed in industrial and high-tech applications. However, the presence of diverse types and states of impurities in quartz ores from different geological formations poses a challenge in the process of purifying high-purity quartz, leading to wastage of raw materials and escalated costs. This study presents the socio-economic applications of quartz, scrutinizes the formation and separation mechanisms of impurities in quartz ores from a mineralogical perspective, examines the obstacles faced in quartz purification, explains the current state of development, and provides a technical summary of quartz purification. The analysis reveals that lattice impurity elements and various types of inclusion impurities are the principal factors affecting the purity of quartz. Various green separation techniques are applied based on the composition of the quartz minerals and the state of the impurities. Standard practices may involve physical pre-treatment such as scrubbing, ultrasonic crushing, and electromagnetic pulse cracking, followed by rough cleaning through color separation, superconducting high gradient magnetic separation, and flotation, and chemical pre-treatment (high-temperature or microwave roasting with chloride doping, and ammonium sulfate thermal crushing combined with water quenching to remove gas-liquid inclusions from quartz minerals). Finally, finishing processes such as fluorine-free and catalytic hot-pressure acid leaching or microbiological purification treatment with filamentous or Aspergillus fungi are used to obtain high-purity silica sand with an anticipated purity of about 99.99%.

The book comprises the proceedings of the 9th Geoscience Conference for Young Scientists co-organized by the Institute of Geology and Geochemistry and the Institute of Mineralogy (Urals Branch of Russian Academy of Sciences) and Ural Federal University and held in Ekaterinburg, Russia, on February 5-8, 2018. The book is devoted to the relevant issues of crystal chemistry and mineral typomorphism; the structure and physico-chemical and technological properties of minerals; the computational modeling of mineral structure and properties. Much attention is drawn to the latest advances and applications of physical methods of investigation of mineral structure and composition, in particular, X-Ray diffraction, spectroscopic (optical, vibrational, ESR, Moessbauer, etc.) and microscopic (SEM, TEM, AFM, etc.) studies, as well as the methods of chemical and isotopic analysis. This book presents the current research trends of space and planetary mineralogy (meteorites, regolites, tektites). The book is intended explicitly for the specialists in the earth and planetary sciences.

This textbook teaches important material and technological fundamentals in various technical systems and applied geoscientific fields. Beginning with the mineralogical characteristics of selected non-metallic raw materials and industrial minerals, this book presents the connections between properties and industrial applications and discusses the environment-relevant aspects as well as problems of biomineralogy. An introduction is given to important mineralogical and physico-chemical aspects of ceramic materials such as silicate ceramics, glass, cement, refractory materials as well as an overview about material synthesis. This makes it the first textbook to present the fundamentals of applied mineralogy as a material-related geoscience in a compact form and to show important bridges to industrial issues and approaches to solutions. It is aimed primarily at undergraduate students of geosciences and materials science, but is also suitable for related disciplines and practical applications.

"Structural Control” remains a crucial point that frequently lacks in any scientific and/or economic analysis of ore deposits, whatever their type and class. The case of lode deposits is exemplary, although also other deposits, like breccia pipe, stockwerk, massive sulphides, skarn, etc., can, surprisingly, be concerned. Several concepts like the gold-bearing shear zone have not proven valid during the last few decades in terms of our understanding of gold deposit and have been totally abandoned. Additionally, the relationships between magmatism, regional tectonic context, and mineralization remain uncertain and have been debated in several recent publications. This demonstrates that this issue is still relevant, and its solution may help in the distinction between intrusion-related and orogenic deposits. In this Special Issue, we particularly invite any case study of mineral deposits, in which it has been demonstrated that structural geology may have a significant role in the establishment of the deposit model of formation and/or on exploration and exploitation programs. Examples in which the structural model diverges from those described in the classical literature are particularly welcomed, including studies in which relationships with magmatism can be suspected and/or demonstrated. Indeed, all cases that illustrate concepts that differ from the classic ones and from theoretical models may represent significant contributions to this volume.
