|Exploration Activity Details|
|Location||Valles Caldera - Sulphur Springs Geothermal Area|
|Exploration Technique||Isotopic Analysis- Rock|
|Activity Date||- 1989|
A series of core holes were drilled from 1984 to 1988 as a part of the Continental Scientific Drilling Program (CSDP) to better understand the stratigraphy, structure, hydrothermal alteration, and subsurface architecture of the Valles caldera. Several authors have reported results from these core holes, including Goff et al. (1986, 1987), Gardner et al. (1987, 1989), Hulen & Nielson (1985), Hulen et al. (1988, 1989), Musgrave et al. (1989), Rowley et al. (1987), Shevenell et al. (1988), and Starquist (1988).
Core from hole VC-2A was sampled every 16 m over the entire length of the hole for compound and elemental analysis. Whole rock isotope samples were taken from these split core intervals, and vein quartz and carbonate samples for isotopic analysis were hand-picked from vein material. Stable isotopic analyses were performed by Geochron Laboratories, Cambridge, MA in accordance with standard methods.
