Journal Article: Isotopic, Chemical And Dissolved Gas Constraints On Spring Water From Popocatepetl Volcano (Mexico)- Evidence Of Gas-Water Interaction Between Magmatic Component And Shallow Fluids

Abstract
Geochemical research was carried out on cold and hot springs at Popocatepetl (Popo) volcano (Mexico) in 1999 to identify a possible relationship with magmatic activity. The chemical and isotopic composition of the fluids is compatible with strong gas-water interaction between deep and shallow fluids. In fact, the isotopic composition of He and dissolved carbon species is consistent with a magmatic origin. The presence of a geothermal system having a temperature of 80-100°C was estimated on the basis of liquid geothermometers. A large amount of dissolved CO2 in the springs was also detected and associated with high CO2 degassing.
