Gold Deposits in the Avalonian Tectonic zone of the Southeastern United States

AUTHORS: Foley, N.K., Ayuso, R.A., Seal II, R.R.

ABSTRACT: Gold- and iron sulphide-bearing deposits of the southeastern United States have distinctive mineralogical and geochemical features that provide a basis to construct models of ore genesis that may be used in the assessment of gold resources. The largest known gold deposits of the region, including subvolcanic quartz porphyry, volcanic-sedimentary rock-hosted, and shearzone-hosted styles of gold mineralization, are primarily hosted by rocks that share a geologic affinity to the classic Avalonian tectonic zone.
