Abstract

Schlumberger soundings were made in the Newberry volcano area of Oregon to categorize the electrical properties of possible Cascade geothermal systems. An east-west geoelectric cross section constructed from the interpreted soundings shows a low-resistivity zone in the caldera, that corresponds to the increase in thermal gradient observed in a U. S. Geological Survey test well. Another low resistivity zone about 600 m deep is present just to the west of the caldera boundary. A north-south geoelectric cross section shows the configuration of the western low-resistivity zone. Maps of interpreted resistivity at depths of 750 and 1000 m show that the main low resistivity area west of the caldera has two tongues, one oriented easterly and the other oriented southerly.
