Stone meteorites type R – Stenmeteoritter type R

Rumuruti – R-type chondrite

The R chondrites are quite different from ordinary chondrites and they are the opposite of the E chondrites when it comes to mineralogy and their state of oxidation. The members of this group are highly oxidized, containing high amounts of iron-rich olivine. There is practically no free metal inside the R chondrites since most of the iron is either oxidized or found in the form of iron sulfides. The iron-rich olivines, along with the oxidized nature of the iron, give most R chondrites a typical red appearance.There are just about 30 R chondrites known if we exclude all probable pairings, especially from the hot deserts of Northwest Africa (NWA).


This is 1 of 17 approved meteorites classified as R3-5.

Breccia composed of discrete well-delineated chondrules plus lithic clasts in a fine grained matrix. Both unequilibrated and equilibrated chondrules are present. Some lithic clasts (Type 5) consist of sparse chondrules in a recrystallized matrix, whereas others consist of separated chondrules in an opaque matrix. Accessory minerals include sodic plagioclase (in the matrix), pyrrhotite, pentlandite, Ti-chromite, merrillite and Cr-magnetite; metal is absent and much of the sulfide is stained orange from secondary alteration.
