Empirical Metallogeny

Empirical Metallogeny: Depositional Environments, Lithologic Associations, and Metallic Ores, Vol. 1: Phanerozoic Environments, Associations, and Deposits, Part B focuses on the composition, characteristics, properties, and reactions of Phanerozoic metallic ore deposits.
The book first offers information on intracrustal and subcrustal environments and plutonic granite, diorite, (gabbro) association (GDG) and its aureole. Discussions focus on petrography, origin, and setting of GDG plutonic rocks; mineralization styles associated with Phanerozoic (higher-level) granite, diorite, (gabbro) association; copper skarns and carbonate replacements; and magnetite skarn and replacement deposits. Manganese, uranium, antimony, mercury, and arsenic deposits, hydrothermal iron ores, and hydrothermal-plutonic silver deposits are also discussed.
The publication also takes a look at high- to medium-grade metamorphosed terrains, katazonal granites and pegmatites and continental fragmentation, rifts, and paleo-rifts. Topics include examples of modern rift and taphrogenic systems; mineralization styles in and related to the zone of ultrametamorphism and granitization; and petrography, origin, and setting of high-grade metamorphic terrains.
The text is a valuable reference for readers interested in the study of Phanerozoic metallic ore deposits.
