Re: Origins



Hello Tim, Bernd and list:
I got the following from McSween's "Meteorites and their parent planets"
(excellent book!!):

349 Dembowska-LL6 chondrites
887 Alinda-H3 chondrites
80 Sappho-C3 chondrites
16 Psyche-E4 chondrites
176 Iduna-C2 chondrites
4 Vesta-Eucrites, Diogenites, Howardites

These are based on spectral reflectance. We also know of the parent asteroids
of many meteorites including Pribram, Farmington, Lost City, Dhajala,
Peekskill, and Innisfree.

Best,
Matt
