Found 2002

Achondrite (howardite)

One fresh-looking stone, weighing 36 g, covered with a cracked fusion crust, was purchased in Morocco. Classification and mineralogy (M. Bourot-Denise, MNHNP): breccia composed of a relatively fine-grained matrix made up of angular crystals, in which 3 kinds of mm-sized clasts are embedded: diogenitic clasts (pyroxene, plagioclase), basaltic eucritic clasts (pigeonite, augite, plagioclase), and granular-textured eucritic clasts. Minor phases include silica in small areas, associated with opaques (ilmenite, chromite, pyrrhotite, rarely metal). Dominant diogenitic orthopyroxene, Fs22.3 Wo1.8; associated plagioclase An83-95. Eucritic pyroxene, Fs35.1 Wo5.8 - Fs52.3 Wo18.3. Low shock stage; weathering grade W1. Specimens: type specimen 7.4 g and one polished mount, MNHNP; main mass with GĂ©rard Merlier.
