Empirical Metallogeny

Empirical Metallogeny: Depositional Environments, Lithologic Associations, and Metallic Ores, Vol. 1: Phanerozoic Environments, Associations, and Deposits focuses on the composition, characteristics, properties, and reactions of Phanerozoic metallic ore deposits. The book first offers information on depositional environments and lithologic associations and the world ocean, including ores and host associations, sea water as a metal source, and metals in marine organisms. The text then elaborates on continental margins, orogenic belts, and ophiolite association. Discussions focus on metal geochemistry and metallogeny, tectonic setting and distribution of ophiolites, trace metals and ore evolution, and supracrustal lithologic associations of orogenic belts. The publication tackles zoned mafic/ultramafic complexes in Phanerozoic orogenic belts; unimodal mafic volcanic-sedimentary association; and unimodal felsic volcanic-sedimentary association. Topics include post-depositional modification of massive sulfides, and interaction mineralization and massive tholeiitic basalt flows and arc affiliation. The book is a dependable source of information for readers wanting to study metallic ores.

Crustal evolution means the resultant changes that the Earth's crust has gone through in its geologic past affected by changes in the mantle-crust system, the atmosphere, the hydrosphere and the biosphere. Metallogeny is the genesis of metallic mineral deposits. Both the terms are used in the book in their conventional sense, but keeping in mind an Indian context. This book is the first of its kind to document in detail the nature, origin and evolution of mineral deposits in India and is contextualized in local, regional and global geology. The book is unique in that it combines both metallogeny and crustal evolution that were hitherto treated as stand-alone topics. The exhaustive chapters in the book carry detailed case studies of the distribution and occurrence of ores. The book would be useful to students of advanced geology, researchers, teachers, planners and global metallogeneticists around the world.

The northwestern Indian Shield, covering a major part of Rajasthan and parts of northern Gujarat, northwestern Madhya Pradesh, Haryana and Delhi, is one of the most important repositories of a variety of mineral deposit types, particularly of base metals. Their metallogeny has been a topic of both academic and economic interest for more than five decades. This volume presents in a systematic manner the essential features of all economically significant types of metallic mineral deposits in this region and considers their mettallogeny in the perspective of crystal evolution of the northwestern Indian shield. Current concepts, problems and the probable trends of future research are highlighted. Leading geoscientists with first hand knowledge of this Precambrian terrene have contributed to this volume. The book will be of interest to exploration geologists, researchers and postgraduate students concerned with Precambrian geology and metallogeny.
