| Abstract | Synthesis of surface and borehole data from the Baca geothermal system, as defined by drilling to date in the Redondo Creek area of the Valles Caldera, New Mexico, indicates that thermal fluid flow in the system is partially controlled by distinct stratigraphic aquifers. These aquifers are relatively thin, laterally restricted beds of nonwelded tuff and tuffaceous sandstone, confined primarily to the Quaternary Bandelier Tuff. Recognition of the role of these rocks in reservoir definition at Baca should improve chances for future geothermal discoveries in the Valles Caldera and similar settings elsewhere. |
