A Group of Papers Devoted to Epithermal Au-Ag Deposits: Preface

Epithermal deposits contribute significantly to global gold and silver production (White and Hedenquist, 1990; Cooke and Simmons, 2000; Hedenquist et al., 2000; Simmons et al., 2005) and continue to be an important target for precious metals explorers. The following group of papers summarizes new knowledge on the geologic setting, structural constraints, and mineralogical and geochemical characteristics of alteration associated with Au-Ag–rich epithermal deposits, primarily from the South Pacific region. This information is used in several …
