Abstract

The curious calcite grains (“groats”) in the Chelosiowa Cave in the Holy Cross Mts. were examined petrographically and isotopically. A model of rapid CO2 degassing due to dehermetization of the cave interior was invoked to explain extremely negative δ18O values (-11 to -21‰ vs PDB) and enrichment in 13C, up to -4‰ vs PDB. The results of petrographic and geologic investigations precluded a hydrothermal origin of the “calcite groats”.
