A stratiform gold occurrence of Precambrian age located 20 milessoutheast of Prescott, Arizona, within the Agua Fria Mining District,displays chemical, mineralogical, structural and lithological patternsindicative of a distal, exhalative volcanogenic environment. Metavolcanicand metasedimentary rocks of the Proterozoic Yavapai Series (1775-1820 m.y.)host the mineralization and are characterized by greenschist grade metamorphism,steeply-plunging penetrative folds and steeply-dipping schistosity.Mineralization is confined to a 100m thick stratigraphic section that iscomprised of a series of thin auriferous massive sulfide beds• and intercalatedschist containing disseminated sulfides. The mineralization extendsmore than 4km along strike. Coincident with ,and largely confined to themineralized strata, are anomalous amounts of As, Sb, Cu, Pb, Zn and Ag andassociated silicification, sericiti2;ation and carbonatization. This exhalativemineralized system is interpreted to have been deposited in apaleotopographic low on the distal flank of a submarine rhyolite dome andto represent the final episode of a Precambrian volcanic cycle.
