The Allende meteorite: evidence for a new cosmothermometer based on Ti3+/Ti4+

Abstract

Applications of the mineral thermodynamic condensation sequence to assemblages in Ca–Al–Ti-rich inclusions in the Allende meteorite suggest that the total amount of titanium and Ti3+ contents of aluminous clinopyroxenes (fassaites) are temperature sensitive and that the ratio Ti3+/Ti4+ may be used as a qualitative cosmothermometer.
