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.
