Abstract
Most high temperature, hydrothermal convection systems probably are hated 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 if 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.
