Geothermal potential along the Balcones/Ouachita trend, central Texas: Ongoing assessment and selected case studies

A synopsis of the geologic conditions along the Balcones/Ouachita trend is presented. The problems in defining low-temperature resources and in recognizing anomalies are addressed. Local geologic and hydrologic conditions are assayed in terms of ambient thermal regimes, and hypotheses are presented for the origin of thermal waters.
