Jiddat al Harasis 626 :
Shocked polymict eucrite
breccia
Polymict breccia composed of both basaltic eucrite and cumulate eucrite clasts plus
related debris. Pigeonite of various compositions (some exhibiting exsolution lamellae of
clinopyroxene within orthopyroxene), calcic plagioclase, silica polymorph, chromite, troilite
and rare zircon. Low-Ca pigeonite (Fs32.1-39.3Wo6.3-5.1; FeO/MnO = 29.5-31.2), clinopyroxene
exsolution lamellae (Fs30.6-33.5Wo31.9-29.8; FeO/MnO = 30.7-31.0), pigeonite (Fs51.8Wo12.7;
FeO/MnO = 30.8). Plagioclase has been transformed by shock into aggregates of fine
anisotropic blades in a subspherulitic texture, indicative of quenching from melt.
