Spar caves as fossil hydrothermal systems: Timing and origin of ore deposits in the Delaware Basin and Guadalupe Mountains, New Mexico and Texas, USA
David D. Decker, Victor J. Polyak, and Yemane Asmerom

  • Spar caves and cave spar form at a spar horizon
  • The depth and temperature of the spar horizon is 500 ± 250 m and 40 to 80°C
  • This temperature overlaps hydrothermal ore deposition and oil maturation temperature
  • Evidence for geothermal systems erodes away, spar caves provide evidence of existence
  • Spar caves may help to locate hydrothermal ore deposits
