Description

A survey of the records of numerous thermally anomalous water wells in the southern portion of the Basin and Range province of Arizona indicate that most of these wells are less than 300 m deep. The temperature and depth data of most of these shallow wells produce abnormally high computed thermal gradients that are inconsistent with considerably lower gradients in deeper wells. Utilization of a method devised for an appraisal of shallow well data permits identification of the most attractive thermal gradient anomalies warranting additional data-gathering methods. Water moving vertically from deep-heated crustal rock along faults and then moving horizontally into relatively shallow basin-fill deposits seems to be the most probable explanation for the irregular but widespread occurrence of thermal ground water in the study area. A significant number of these occurrences appear to have thermal gradients potentially adequate for non-electrical energy utilization. Report on thermal gradient anomalies of southern Arizona, 49 p., 3 map sheets, scale 1:1,382,400.
