Lithologic Descriptions and Temperature Profiles of Five Wells in the Southwestern Valles Caldera Region, New Mexico
Abstract The subsurface stratigraphy and temperatur
The subsurface stratigraphy and temperature profiles of the southern and western Valles caldera region have been well constrained with the use of data from the VC-1, AET-4, WC 23-4, PC-1, and PC-2 wells. Data from these wells indicate that thermal gradients west of the caldera margin are between 110 and 140°C/km, with a maximum gradient occurring in the bottom of PC-1 equal to 240°C/km as a result of thermal fluid flow. Gradients within the caldera reach a maximum of 350°C/km, while the maximum thermal gradient measured southwest of the caldera in the thermal outflow plume is 140°C/km. The five wells exhibit high thermal gradients (>60°C/km) resulting from high conductive heat flow associated with the Rio Grande rift and volcanism in the Valles caldera, as well as high convective heat flow associated with circulating geothermal fluids. Gamma logs run in four of the five wells appear to be of limited use for stratigraphic correlations in the caldera region. However, stratigraphic and temperature data from the five wells provide information about the structure and thermal regime of the southern and western Valles caldera region.
