Carbonaceous chondrite (CR2)

Eight fully to mostly crusted stones, weighing a total of 1705 g, were purchased in Rissani (2001). The local finders say that these stones defined a strewnfield ~1.5 km long and within a few kilometers of Zagora. Classification and mineralogy (T. Bunch and J. Wittke, NAU): chondrules account for 63 vol%; small chondrules (<1.5 mm) tend to be round and metal-poor, large chondrules (<4.0 mm) are mostly irregular-shaped with abundant metal (kamacite = 5.2–6.0 wt% Ni). Olivine, Fa1.3–2.1; orthopyroxene, Fs2.2–3.2Wo0.8; plagioclase, An95–97; pyrrhotite (Ni = 1.4 wt%); phyllosilicates, serpentine-greenalite series (Mg > Fe); chondrule and matrix glasses are Mg, Al-rich, Na, K-poor; fine-grained (<0.05 mm) refractory inclusions contain diopside (Wo49–52, Fs1), spinel (FeO = 0.25 wt%), and gehlenite. Shock stage, S1; weathering grade, W2. Specimens: type specimen, 19.7 g and one thin section, NAU; main mass is with the purchaser.
