Description
Rumuruti chondrite (R4), Found in Northwest Africa, Classified April 2018
The R class of chondrites is one of the rarest classes of chondrites. This full slice falls into one of only 60 total known meteorites with an R4 classification!
Petrography: (A. Irving and S. Kuehner, UWS) The specimen is a breccia mostly composed of well-formed, relatively small chondrules (apparent diameter 250±150 µm, N = 12) in a finer grained matrix (~30 vol.%), but some petrologically-similar, angular lithic clasts (including type 3 and type 4 clasts) are also present. Both olivine and orthopyroxene have very magnesian cores, but the predominant mafic minerals are much more ferroan. Other minerals are clinopyroxene, sodic plagioclase, pentlandite, pyrrhotite and magnetite. – As listed by the Meteoritical Bulletin
