Book Description
This book provides a brief geology, tectonic structure and metallogeny of Mongolia, central part of the giant Central Asian Orogenic Belt, and broad overview of major metallic (copper, gold, rare metals and rare earths, iron, lead and zinc, silver and platinum group), non-metallic (phosphorite and fluorspar) and fuel (uranium and coal) mineral deposits and occurrences, covering their tectonic position, metallogeny and deposit types, geological characteristics and origin, including newly found deposits and occurrences based on authors research data and a large information obtained during geological exploration work. The book is intended for professional economic geologists, for earth science students and practicing geologists.

Book Description
This book presents a synthesis of the principal environmental characteristics of the Cretaceous in East and South Asia. The research was accomplished under IGCP project 350, which deals with the biological, climatological and physical environments of this region during the Cretaceous. This synthesis discusses aspects of stratigraphy, sedimentology, paleontology, geochemistry, tectonics, petrology, mineralogy, and geophysics. The research results are summarised by country, and include Far East Russia, Mongolia, eastern China, Korea, Japan, Philippines, Vietnam, Laos, Cambodia, Thailand, and India. Although these countries do not encompass the entire region, this coverage provides an excellent perspective of the evolution of the region during the Cretaceous. The records incorporated in this book present a wealth of marine and nonmarine data on climate, biotic diversity, circulation and chemistry of the ocean as well as fundamental plume tectonism. The latter appears to have caused much of the environmental change in this broad region, including both an enhanced greenhouse effect and high sea levels.

Book Description
The monograph is concerned with results of studies of petrology of mafic-ultramafic massifs as part of the East Sakhalin ophiolite association. It generalizes and interprets a large body of data (mainly original data) on geology, petrography, petrochemistry, and geochemistry of rocks; mineralogy and geochemistry of rock-forming and accessory minerals; chromite and platinum contents, and isotopic age of zircons from rocks of the typical mafic-ultramafic massifs of the East Sakhalin ophiolite association: Berezovka, Shel’ting, Komsomol’sk, and South Schmidt. Gabbroids from the Berezovka massif contain ultramafic xenoliths. Ultramafic rocks are locally cut by gabbroid and pyroxenite veins. Three spatially close but genetically autonomous bodies are distinguished in the structure of the massifs under study: protrusion of upper-mantle restitic ultramafic rocks (harzburgites, lherzolites, and dunites); intrusion of orthomagmatic gabbroids (gabbronorites, gabbro, and norites) that cuts it; and contact-reaction zone, located along the boundaries between gabbroid intrusion and ultramafic protrusion, which consists of hybrid ultramafic rocks (wehrlites, websterites, clinopyroxenites, and their olivine- and plagioclase-containing varieties) and hybrid gabbroids (melano- and mesocratic olivine gabbronorites and gabbro as well as troctolites). The hybrid ultramafic rocks and gabbroids are the product of interaction between mafic melts and restitic ultramafic rocks. Taking into account the later formation of the gabbroid intrusions compared to the ultramafic protrusions, the massifs in question are determined as polygenic. The idea of their polygenic formation is supported by data on the isotopic age of zircons from the Berezovka massif rocks. In this monograph the author develops his earlier proposed concept of polygenic formation of mafic–ultramafic massifs belonging to ophiolite associations. The book addresses a wide circle of petrologists and practicing geologists as well as senior-year students and postgraduates studying problems of mafic-ultramafic magmatism.

Book Description
Discovery of Oyu Tolgoi: A Case Study of Mineral and Geological Exploration provides a detailed account of the exploration for copper deposits that took place in Mongolia in the mid-1990s, an exploration that was first started by Magma Copper and then continued by BHP Billiton World Exploration Inc., and which subsequently lead to the discovery of Oyu Tolgoi, a major metal mine. This book commemorates the 20-year anniversary for the global mining industry, including details on exploration methods, the tools applied throughout the discovery, and how the applied models evolved over the course of the execution of the exploration program. In addition, the book presents how the knowledge of the team evolved as they further understood the regional geology and the necessary geological conditions for a significant porphyry discovery. Includes a detailed description of the anthology of the Oyu Tolgoi mine discovery, a major copper-gold porphyry deposit Offers practical lessons for exploration companies through coverage of the critical factors that lead to the success of the discovery, along with the institutional factors that hindered discovery Features nearly 70 never-before-seen full-color illustrations and photos of Oyu Tolgoi
