The Modeling Near-Surface Processes in Mineral Systems project is investigating the environmental geochemistry of a group of unmined volcanogenic massive sulfide (VMS) deposits in the Bonnifield mining district, Alaska Range, east-central Alaska. The pyrite-rich Red Mountain (also known as Dry Creek) deposit is the best exposed of these deposits and displays a remarkable environmental footprint of natural acid generation, metal dissolution, metal precipitation, and self-mitigation processes.

This data series contains the geochemical data for stream sediment, surface-water, rock, precipitate, and vegetation samples from Red Mountain. The report describes the deposit's geologic setting and methods of study including sample collection, preparation and analysis. Included in the data series are maps of the study area, citations of relevant references, descriptions of analytical techniques and limits of determination, photographs of each sample site, and the geochemical database in MS Access format.
