[Geological Data] Basin-hosted (CD/SEDEX and MVT) Zn-Pb deposits and prospects for the United States, Canada, and Australia

This compilation contains a list of approximately 8,600 sites across the United States, Canada, and Australia where Zn-Pb-mineralized rock is attributed to basinal brine-related mineralizing processes, specifically assigned to Mississippi Valley Type (MVT) or clastic-dominated (CD) deposit types; a second group of 147 sites, classified as “unknown”, but which may have similar genesis, is also included. These sites were selected based on interpretations of 16 published databases, including the Mineral Resources Data System (USGS, 2016) and the Alaska Resource Data File (USGS, 1996) for the United States, and comprise a significant but not necessarily complete dataset. Each site is further classified by deposit type and development status. For the limited deposits where grade and tonnage information are available, tonnage and published Cu, Zn, Pb, Ag, and Au grades are provided. References for source data are also included.
