Found 2003

Carbonaceous chondrite (CK)

A 35.7 g stone was purchased in Rissani, Morocco in September 2003. Description and classification (T. Bunch and J. Wittke, NAU): Partially shock-melted/crystallized CK (S3-6) of undeterminable petrologic grade. Cataclastic matrix consists of a massive network of small-grained olivine (Fa31) with many microns-size magnetite inclusions (Cr2O3, 0.57 wt. %; Al2O3, 3.1 wt. %) and plagioclase (An29.3). Several chondrules with thick, fine-grained rims, are mantled with quench-form, alumina-rich (5.6 wt. %), low-Ca pyroxene (Fs23.2En76.8), set in Ca-rich mesostasis. Many other chondrules also show characteristics of partial melting. Moderate weathering grade. Specimens: 7.8 g, NAU; main mass, Oakes.
