Carbonaceous chondrite (CK4)

A 440 g single, brownish stone was purchased in Erfoud, Morocco in May 2004. Description and classification (T. Bunch and J. Wittke, NAU): contains ~ 33 vol. % chondrules that are typically smaller than most CK meteorites (<1 mm diameter), abundant  melilite–spinel CAIs rimmed by subcalcic augite, and partially rcrystallized matrix. Matrix olivine, Fa 29.5–34.2, FeO/MnO = 30.8–37.8, NiO = 0.35 ± 0.12 %; low–Ca pyroxene, Fs25.3–29.0Wo0.9–5.3, FeO/MnO = 25.3–29.0; plagioclase, An36.8–51.2 Or1.7–3.0; magnetite, Cr2O3, = 5.3 wt %, Al2O3, 5.3 wt %, TiO2 = 1.97 wt %, NiO = 0.27 ± 0.1 %, troilite, and Fe-, Mg-rich feldspathic glass. A portion of the glass has been replaced by terrestrial carbonate. Shock level is S2, weathering grade, W3. Specimens: type specimen, 23 g, NAU; main mass. Reed.
