Abstract
An integrated geological, geophysical and geochemical study ahs been underway in the Newcastle geothermal area of southwest Utah. Electrical resistivity and self potential studies were undertaken late in the study in an attempt to provide additional delineation and characterization of this blind geothermal system. The electrical resistivity data detect the outflow plume and with numerical modeling, indicate the probable up flow zone of the thermal fluids. Self potential data map a well defined minimum between the higher temperature shallow gradient holes and this is interpreted to be the principal conduit of fluids which feeds the outflow plume.
