Item for auction is a 6.42g full slice of my new NWA 7130 LL3 chondrite, with 242g of partially crusted material recovered in September 2011. Montana Meteorite Laboratory cut and prepared this piece, which features well defined chondrules in a dual lithology matrix sprinkled with nickel-iron blebs. Fairly closely packed, well-formed, large chondrules (some with thin opaque rims). Olivine (Fa1.9-81.6; Cr2O3 in ferroan examples is 0.02-0.27 wt.%, mean 0.11 wt.%, s.d. 0.10 wt.%, N =8), orthopyroxene (Fs12.0-24.3Wo2.8-1.3), clinopyroxene (Fs8.9-12.0Wo41.8-39.0), sodic plagioclase, altered kamacite, chromite, troilite and taenite.
