EVALUATION OF THERMAL METAMORPHISM TEMPERATURE OF EQUILIBRATED ORDINARY CHONDRITES
The article provides an evaluation of thermal metamorphism temperatures on chondrite parent bodies using an olivine-Сr spinel geothermometer. To calculate temperatures, the results of EPMA analysis of the major and trace elements in olivine and Cr spinel
