The petrogenesis of the Rio Blanco Au-Ag mineralization in the Cordillera Occidental (Western Cordillera), southwest Ecuador, was assessed using magmatic host rocks and ore constituents geochemical and isotopic (S, O, H, Pb and Sr) composition. The magmatic rocks spatially associated with the Rio Blanco Au-Ag mineralization are of arc affinity and mostly include lava flows of andesitic composition, as well as plutons and pyroclastic falls that range from dioritic (andesitic) to granodioritic (dacitic) compositions. These arc rocks as evidenced by their initial Sr isotope compositions (87Sr/86Sri: 0.70443–070694), which are symptomatic of crustal contamination, are of two contrasting magmatic suites (transitional and calc-alkaline), and typi...
