Monomineral universal clinopyroxene and garnet barometers for peridotitic,eclogitic and basaltic systems

摘要

New versions of the universal Jd-Di exchange clinopyroxene barometer for peridotites,pyroxenites and eclogites,and also garnet barometer for eclogites and peridotites were developed.They were checked using large experimental data sets for eciogitic(~530) and peridotitic systems(>650).The precision of the universal Cpx barometer for peridotites based on Jd-Di exchange is close to Cr-Tschermal
