| Abstract: | The historic development of the first geobarometer for spinel lherzolite based on thedistribution of calcium between existing olivine and clinopyroxene is reported here. Kohler and Brey(1990)suggested the geobarometer as follows:Based on their calibrated experiments for calcium exchange between olivine andclinopyroxene from wide temperature-pressure range. |
