Abstract
This survey probes the geothermal resources of a large (50 by 170 km) area in the Tucuman province, Argentina. The main interpretive tools used are stable isotope compositions, and the Na-K-Ca/Mg and CCG cationic geothermometers. Forty one water samples from 40 water wells and 1 river were collected and analyzed. Our results clearly indicate the presence of waters of geothermal origin, and widespread thermalism. Commercial size "hot spots" with temperatures appropriate for most direct applications and for binary cycle technology electric power production are indicated by the survey results.
