Carbonaceous chondrite (CR2)

History: M. Farmer and G. Hupe recovered a total of approximately 5 kg of many individuals and fragments from Zagora, Morocco. Many whole and sliced specimens have been sold over the last several years.

Physical characteristics: Many whole stones and fragments, all with desert varnish and brown/orange color. Numerous chondrules, many on the order of ~ 1 mm in apparent diameter, are visible.

Petrography: (G. Benedix and C. Smith, NHM) The thin section studied is dominated by millimeter-sized Type I PO and POP chondrules, which are often rimmed with and/or contain metallic Fe-Ni blebs. Metallic Fe-Ni also occurs as rounded, millimeter-sized grains within the matrix. Interstitial to chondrules and metal is a fine-grained matrix rich in phyllosilicate.Two Type II chondrules were also observed. Pervasive veins of rust occur throughout.

Mineral compositions: Type 1 chondrule olivine (Fo98.2±1.3), low-Ca pyroxene (En96.2±0.9Wo2.0±2.2), high-Ca pyroxene(En45.7±11.5 Wo35.9±4.7). Type II chondrule olivine (Fo77.4±7.7), low-Ca pyroxene (En73.8±1.8Wo2.1±2.4).

Classification:Carbonaceous chondrite (CR2); moderate to extensive weathering.

Type specimens: A total of 77.4 g of sample and two sections are on deposit at NHM. MFarmer holds several grams, KCCU holds approximately 10 g, AMNH hold several grams.
