The book is an historical monograph on deep-sea mineral-related activities and attitudes towards deep-sea mining in the 20th Century which makes comparisons with the current situation in regard to those activities and attitudes. It reviews developments in the study of, and prospects and plans for mining deep-sea manganese nodules, cobalt-rich crusts, hydrothermal deposits, and phosphorites, and discusses associated environmental, technological, and economic issues. It is based on several sources. First, the author’s experience gleaned from around 50 years of attending conferences on the subject (the most important of which was the annual Underwater Mining Institutes held from 1970 onwards at which much of the material in the book was first exposed), second, discussions with and advice from the author's colleagues on the subject, all attributed, and third, the published literature.

This book explores the topic of gyrolite and calcium silicate hydrates, focusing on their potential applications in wastewater purification and as additives in ordinary Portland cement. Divided into five chapters, the book provides a comprehensive description of calcium silicate hydrates and addresses challenges in reusing solid waste. It also covers the synthesis and application of gyrolite, offering technological recommendations for future studies. The results presented are supported by instrumental analysis techniques and thermodynamic calculations, allowing readers to delve into inorganic chemistry and materials characterization. The book is suitable for both researchers and students interested in chemistry and materials characterization, offering valuable insights and guidance in the field.

This volume includes chapters that discuss the mineralogy, petrology, and geochemistry of granitic rocks, mechanical properties of some granitic rocks, production of synthetic quartz, dislocation originated by X-ray irradiation in KBr crystals and mineralogy and geochemistry of bituminous rocks from North Africa.

Solid-solution equilibria of marine evaporites are important in a wide range of science and technology. However, the data had not yet been summarized in a form that is at the same time comprehensive and permits to understand how the quinary seawater system builds up from its bounding systems. Thus the goal of the present volume is at the same time scientific and educational. The understanding of solid-solution equilibria of the various systems with respect to dissolution, precipitation and transformation of solids, their application to the evolution of brines, and a fast access to data is a necessary requirement for any modelling, especially in Geoscience. Another goal is to show the avail­ ability of data. Unfortunately, though solubility data are numereous there are substantial gaps, especially with respect to high temperatures. But also up to about 100 0 C data are missing for some of the systems so that they cannot be described entirely. Based on the present volume further work on the solubili­ ties of the minerals of marine evaporites may be promoted. The data have been viewed and collected over several years by the first author. The second author entered the preparation of the volume when it was realized that besides graphics and tables a fast access to data was required. Although both authors are responsible for the whole volume, responsibility is weighted somewhat differently for the various parts.

This book is the first systematic treatise of available data and view-points obtained from geological and geochemical studies of the Mo deposits in Qinling Orogen, China. Qinling Orogen has a minimum reserve of 8.7 Mt Mo, ranking the largest molybdenum province both in China and the world. Incorporating all known Mo deposit types in the world, it presents extensive studies of Mo deposits of world-class and unusual types within tectonic settings.

As one of the eighteen field-specific reports comprising the comprehensive scope of the strategic general report of the Chinese Academy of Sciences, this sub-report addresses long-range planning for developing science and technology in the field of mineral resources science. They each craft a roadmap for their sphere of development to 2050. In their entirety, the general and sub-group reports analyze the evolution and laws governing the development of science and technology, describe the decisive impact of science and technology on the modernization process, predict that the world is on the eve of an impending S&T revolution, and call for China to be fully prepared for this new round of S&T advancement. Based on the detailed study of the demands on S&T innovation in China's modernization, the reports draw a framework for eight basic and strategic systems of socio-economic development with the support of science and technology, work out China's S&T roadmaps for the relevant eight basic and strategic systems in line with China's reality, further detail S&T initiatives of strategic importance to China's modernization, and provide S&T decision-makers with comprehensive consultations for the development of S&T innovation consistent with China's reality. Supported by illustrations and tables of data, the reports provide researchers, government officials and entrepreneurs with guidance concerning research directions, the planning process, and investment.

In this book, readers will gain a deep understanding of the distinct characteristics and intricate formation mechanisms behind each type of diamond.

Prepare to be dazzled by this shining and sumptuous visual guide to the world's greatest treasures.

This book composes the proceedings of the international conference on Geo-Spatial Technologies and Earth Resources (GTER 2022) which was co-organized by Hanoi University of Mining and Geology and the International Society for Mine Surveying (ISM) held at Hanoi city on October 13–14, 2022.
