Cryogenic cave carbonate and implications for thawing permafrost at Winter Wonderland Cave, Utah, USA

Abstract Winter Wonderland Cave contains perennial ice associated with two types of cryogenic cave carbonate (CCC) formed during the freezing of water. CCCfine is characterized by relatively high δ13C values, whereas CCCcoarse exhibits notably low δ18O values indicating precipitation under (semi)clo...
