Abstract

CML 215 and CML 392 are two unclassified meteorites that belong to the class of Rumuruti (or R) chondrites. Using optical thin section microscopy both specimens were preliminary classified as R3-5. Both meteorites contain hydrous phase amphibole, which indicate interaction of the parent body (or bodies) of these meteorites with OH- oxidant. Presence of this phase in CML 215 and 392 brings the number of amphibole-bearing R chondrites to three. At this point is uncertain whether CML 215 and 392 are paired.
