Most high-temperature, hydrothermal-convection systems probably are heated by bodies of magma (and/or hot plutons), whose presence is suggested by geologically young, if not active volcanism. Study of a young volcanic area provides information about the general thermal status of the underlying heat source, and detailed information about the time-space-volume-composition (TSVC) characteristics for a volcanic area can help define temperature at least semi-quantitatively when interpreted within the framework of published magma-cooling models. Thus, TSVC study is a fairly powerful and cost effective tool in the pre-drilling phase of an exploration program in young volcanic terrane. Examples are described for Coso, California; Agua de Pau, Azores; and Tecuamburro, Guatemala.
