| Research Abstract |
In this research project we proposed new geothermobarometers from the experimental fruits performed at a wide pressure range covering from an atmospheric pressure to the ultrahigh-pressure equivalent to the lower part of the upper mantle of the earth. Combining the experimental results with the geological, petrological and geochemical evidences of metamorphic rocks, we proposed the newmethods to calibrate the pressure-temperature path of metamorphosed rocks under the extreme conditions occurring at Napier, Lutzow-Holm and Sor Rondane Complexes.
