Gold and copper deposits in Central America are hosted by island arc volcanic rocks of Late Cre-taceous and younger age. Low potassium tholeiitic basalts form the base of the volcanic pile and were deposited in an intraoceanic island arc. Volcanism became more potassic with time, and by Late Miocene time, calc-alkaline andesites dominate the volcanic rock record. Alkaline volcanic rocks appeared about five million yearsago but are underreported in older portions of the arc.Porphyry copper deposits are centered on calc-alkaline plutons of intermediate (quartz diorite to quartz monzo-nite) composition and are typically anomalous in gold. Although some of the porphyry deposits contain in ex-cess of a billion tonnes, none are in production. Bon...
