Exploration Basis
Geochemical water sampling, mineral distribution mapping, and shallow (30 cm) temperature probe measurements were conducted to expand on a previous field mapping study of surface geothermal features at Salt Wells, in order to evaluate the relationship between these features and structures that control geothermal fluid flow.
 
Notes
The distribution of sinter deposits and siliceous surface alteration are described in detail by Coolbaugh et al. (2004), and were mapped using the same iPAQ pocket computer and GPS device described in that study. Advanced argillic alteration was also mapped along the southern end of the thermal anomaly defined during this study, and is believed to evidence the effects of acid steam condensation associated with now-extinct fumarolic activity. The authors concluded that the semi-continuous distribution of silicification and warm ground along the northwestern margin and central portion of the Salt Wells basin define a 6-km-long, thermally active north- to northeast-striking structure that broadly aligns with the thermal anomaly identified by the early Anadarko geothermal gradient drilling. This thermal anomaly is thought to relate either to northward flow of thermal groundwater in the subsurface from the inferred zone of upwelling in the southwest corner of the basin, or to intermittent upflow along the north- to northeast-striking structure on the basin’s western margin.
