Ordinary chondrite, unequilibrated (LL3.2; S3; W0)
Fall, 21 January 1946; 50 kg

A shower of stones fell with ~25 kg being recovered almost immediately and another ~25 kg recovered later. The Krymka meteorite is an unusual unequilibrated ordinary chondrite which has received considerable additional attention in recent years. As with other unequilibrated ordinary chondrites, Krymka possesses abundant, distinct chondrules [porphyritic olivine (PO) and porphyritic olivine-pyroxene (POP) chondrules are especially prominent] embedded in a matrix with additional olivine and pyroxene grains and clasts, Fe-Ni metal, troilite, and other minor opaques. The olivine is highly unequilibrated with chondrule olivine usually more forsteritic [Fa0-24] and matrix olivine more compositionally varied [Fa6-92]. Fe-Ni metal also exhibits some unusual compositional variants. Si-bearing kamacite is reported in troilite and minor Co-rich-tetrataenite is reported. Undulose extinction in olivine is one indicator of some very strong pre-terrestrial shock. Tiny grains of presolar material are also present. [Some — but not all — of these findings have been reported in Russian.] A cosmic ray exposure age of ~28 Ma is reported.

Krymka is one of only 44 witnessed unequilibrated ordinary chondrites falls listed at the Meteoritical Bulletin Database (mid-September 2015). Only 2 of them (Krymka and Vicência) are listed specifically as petrologic type LL3.2 (Very low in iron, unusually primitive [undifferentiated, little evidence of metamorphism]). Nearly twenty LL3.2 meteorites in all are reported but the others are finds and all weathered to some extent. Most of the separately listed finds are from Northwest Africa and thus of uncertain provenance (i.e., they may be fragments of single falls separated by humans rather than nature.). A few tiny Antarctic finds are also in the group. In any case, Krymka is a very rare type of meteorite.
