Supergene Metal Deposits

October 2015, Vol. 11, No. 5

Supergene metal deposits form when deeply buried orebodies are exposed at the surface and undergo oxidation, dissolution, and significant reconcentration of metals. Much of the global economic and scientific interest in these ores stems from their mineralogical diversity and advantages for exploitation due to their surficial development and increased grades. Supergene deposits contribute significantly to the world’s supply of metals, such as copper, aluminum, and nickel. They are also increasingly being explored and exploited as alternative sources for “critical metals,” including rare earth elements and strategic metals, which are widely used in technology and low-carbon energy applications. Furthermore, supergene metal deposits provide clues about our past climate and offer an unparalleled opportunity to explore the long-term corrosion behavior and environmental impact of natural and man-made materials. This issue of Elements highlights some of the most recent advances in the field, including cutting-edge research in economic geology, paleoclimate and geoarcheology studies, environmental geochemistry, geobiology, and corrosion science.
