Mountain permafrost in the Central Pyrenees: insights from the Devaux ice cave

Abstract: Abstract. Ice caves are one of the least studied parts of the cryosphere, particularly those located in inaccessible permafrost areas at high altitudes or high latitudes. We characterize the climate dynamics and the geomorphological features of Devaux cave, an outstanding ice cave in the Central Pyrenees on the French-Spanish border. Two distinct cave sectors were identified based on air temperature and geomorphological observations. The first one comprises well-ventilated galleries with large temperature osci… Show more

“…In some caves, the occurrence of non-carbonate minerals of cryogenic origin has been reported (Dublyansky et al, 2017;Žák et al, 2018). Cryogenic gypsum and, locally, other sulphate minerals are mostly known from caves hosted in gypsum rock (Kadebskaya and Tschaikovskiy, 2015;Žák et al, 2018) but also from some limestone caves where the sulphate is derived from pyrite oxidation (Bartolomé et al, 2022;Dublyansky et al, 2017). Mirabilite is known from several caves where its existence has been tied to evaporative conditions (e.g., 240 Audra and Nobécourt, 2013;Bieniok et al, 2011).…”
