Hello, 



just cutted and well polished, one of my newly classifeid, a LL6 breccia (W1, S2) with some clast described as metachondrite... Some brown/oxyde part circa the Fe,NiS of this meteorite, I offer 7 slices for a cheap 5/g and one individual for 3/g !

Coarse breccia composed 

predominantly of recrystallized clasts containing some remnants of large
chondrules.  Olivine (Fa30.2±0.10), orthopyroxene (Fs24.1-24.2Wo1.9-2.4),
clinopyroxene (Fs9.6-9.8Wo43.3-43.0), sodic plagioclase, chromite,
troilite, kamacite (exhibiting minor staining) and taenite. A large, rounded,
finer grained LL metachondrite clast is completely recrystallized, and contains
olivine (Fa30.0-30.7) and orthopyroxene (Fs23.7-24.5Wo1.0-1.6)
of very similar composition to the respective minerals in the LL6 breccia
clasts.
