Diogenite, pyroxenite
Fell 9 Jun 1843, 50 g
A large stone was seen to fall, broken into pieces, and only a few ounces were preserved. These small remnants represent the first of only 11 witnessed Diogenites falls. Diogenites are plutonic rocks, usually rich in orthopyroxene, and are members of the HED suite of meteorites believed - in the main - to be fragments of the asteroid 4 Vesta. In addition to its Mg-rich orthopyroxene (En~80; > 90 vol%) and its tiny exsolution clinopyroxene lamellae, Manegaon silicates include minor amounts of both olivine and anorthitic plagioclase. Opaques are similar to those reported in other Diogenites and include chromite, troilite, and Fe-rich metal (with only 3% Ni). Fluorapatite has also been reported.
Minor variations in the reported abundances of our references can presumably be attributed to sampling problems. Slight differences in abundances compared to to other diogenite pyroxenites presumably reflect somewhat heterogeneous magmas in the original parent body. The diogenite falls are remarkably similar in their overall petrography and mineralogy. [The situation with finds is more complicated as some olivine-rich diogenites (e.g., dunites) have also been found.]
