DEUTERIUM AND OXYGEN-18 OF NITROGEN THERMS WATER OF BAUNT GROUP (BAIKAL RIFT ZONE)
Isotopic composition of therms corresponds to meteoritic waters but an oxygen shift towards the line in the direction of Craig's weighting is observed, it is explained by evaporation of water on the surface. It is assumed fractionation of deuterium and oxygen during interaction of water - silicate rocks interaction.
