Equilibration temperatures of the ordinary chondrites - A new evaluationThe novel calibrations of the Ca-pyroxene thermometer accomplished by Kretz (1982) and Lindsley (1983) are presently applied to 24 analyzed pyroxenes from 24 H6, L6, and LL6 chondrites. Both thermometers indicate that the H group equilibrated to significantly lower temperature (820-830 C) than the L and LL groups, yielding values of 860 C (Lindsley) to 930 C (Kretz).
