Ca‐, Al‐rich Inclusions in Three New Carbonaceous Chondrites from the Grove Mountains, Antarctica: New Evidence for a Similar Origin of the Objects in Various Groups of Chondrites
Abstract Three new carbonaceous chondrites (GRV 020025, 021579 and 022459) collected from the Grove Mountains (GRV), Antarctica, have been classified as the CM2, CO3 and CV3 chondrites, respectively. A total of 27 Ca‐ and Al‐rich inclusions have been found in the three meteorites, which are the earl...
