Journal Article: Physical-Chemical Conditions Of The Teide Volcanic System (Tenerife, Canary Islands)

Abstract
The Teide volcano (3717 m) is the central structure of the island of Tenerife and at present its morphology is that of a stratovolcano which has grown on a large caldera with a collapse 17 km in diameter, which was generated some 0.6 million years ago. The different studies that have been carried out seem to indicate that, in a oversimplified model, there is an intermediate magma chamber with an approximate volume of 30 km3 and located 2-3 km below the actual base of the caldera, i.e., almost at sea level, with a temperature of 430 ± 50°C, and a pressure of 400 ± 100 bar. The summit fumarole emissions are 85°C and are formed mainly of CO2 with small amounts of sulphur species, H2, CH4 and He. The water vapor (68-82%) emitted with the gases comes from the vaporization of a perched aquifer in the upper cone, as shown by the isotopic analyses.
