Summary:

This report describes field geological and geophysical investigations of the Marysville geothermal area, including geological mapping, sample collection, a ground total field magnetic survey, gravity survey, seismic ground noise survey, microearthquake survey, and heat flow study. Although sufficient data are not available, it is likely that a magma chamber is the heat source. A second section, ''Contemporary Seismicity in the Helena, Montana, Region'' examines the coincidence of high heat flow and earthquake swarm activity in this region. (GRA)
