The completion of the USGS’s Global Mineral Resource Assessment for porphyry copper deposits (Hammarstrom and others, 2013; Johnson and others, 2014) provides a new worldwide database of porphyry copper deposits and prospects that allows examination of how the resource characteristics of porphyry-style deposits vary by tectonic setting and other spatial and temporal characteristics. The new database is distinctly larger than the one published by Singer and others (2008), which contained 422 deposits. The new database contains 452 deposits (and excludes Precambrian deposits). Most of the newly compiled deposits are in Australia, Turkey, Iran, and China. These new data allow us to explore how some of the traditional classifications of porphyry-style deposits present taxonomic challenges.
