Natural dissociation of olivine and clues to the olivine-ringwoodite transformation in Bori L6 chondrite
ONLINE POSTER SESSION FOR PLANETARY SCIENCES IV
planetary sciences | 25 january 2024
Rajesh Kumar Behera, Sujoy Ghosh, Kishan Tiwari, D...
We studied the heavily shocked Bori L6 chondrite, consisting of shock melt vein (SMV) and the melt-pockets (MP). The host rock consists of olivine, lo...
