(c) Chemical composition of free gas (vol. %), which characterized feeding reservoir of Velikan geyser. Sampling was performed by A. V. Kiryukhin in Sept. 2013 from hot degassing pool located 8 m from Velikan geyser. Sample (1) was analyzed by V. I. Guseva in IVS FEB RAS; sample (2) was analyzed by V. Y. Lavrushin in GIN RAS. Isotopic analyses (δ13C) were performed by B. G. Pokrovsky
