Formation of Gold Deposits Phillips Neil
This book addresses the origin of gold deposits to answer questions of science and curiosity. Initially there is a summary of the methods used to address the genesis of gold deposits including some of the essential science and concepts. These answers contribute in turn to the improved exploration and mining of gold.
Magmatic processes enriching gold are discussed followed by the role of aqueous fluids during gold deposit formation at elevated temperatures and pressures. Five basic observations follow that apply to many gold deposits and need to be considered in any genetic ideas. Modifying effects after deposit formation include high-grade metamorphism, retrogression, weathering, and erosion.
The main types of gold deposits are then explained within the spectrum of viable genetic ideas, with informal names for these examples that include gold-only, gold-plus, Carlin, slate-belt,
