NWA 7184 CR2 Carbonaceous Chondrite Meteorites for Sale

Location: Northwest Africa, exact location unknown.

Found: Purchased in 2009

Classification: CR2 Carbonaceous Chondrite (S2, W2)

Description: Well-formed, separated, medium-sized chondrules in a dark brown, very fine grained matrix containing hydrous minerals (including cronstedtite), Ni-bearing sulfides and rare chlorapatite. Olivine (Fa_1.5-51.5; Cr₂O₃ in ferroan olivine 0.06-0.38 wt.%, mean 0.20 wt.%, s.d. 0.13 wt.%, N = 8), orthopyroxene (Fs_2.6Wo_0.3), pigeonite (Fs_27.3Wo_14.5), augite (Fs_15.2Wo_45.6), chromite and troilite. Oxygen isotopes determined on acid-washed subsamples by laser fluorination at Okayama University (d¹⁷O = 0.33, 0.84; d¹⁸O = 4.12, 4.74; D¹⁷O = -1.844, -1.652 per mil) plot in the established range for CR chondrites. Petrography and analysis by A. Irving.

Comment: This CR2 is priced somewhat lower than NWA 801 or DHO 1432 because it is more weathered. This should be one of the best deals available for this rare class.
