Writeup from MB 106:
Northwest Africa 8335 (NWA 8335) (Northwest Africa) Purchased: 2013 Classification: Carbonaceous chondrite (CV3) History: Purchased from Aras Jonikas (USA) who bought the sample from a Moroccan dealer. Petrography: (K. Metzler, IfP) Chondrules, CAIs and AOAs are embedded in a fine-grained dark matrix (about 30 vol% matrix). Most chondrules have apparent diameters between 0.3 and 1.8 mm, some up to 4.2 mm. Several chondrules show reddish staining due to terrestrial weathering. CAIs with sizes up to 5 mm and dark inclusions up to 2.5 cm are observed. Geochemistry: Random measurements of olivine grains revealed Fa9.4±10.1 (Fa1-42); n=23. Random measurements of low-Ca pyroxene grains revealed Fs1.4±0.6Wo1.3±0.9 (Fs1-4Wo1-4); n=19. Classification: CV chondrite based on CAI and AOA occurrence, size of chondrules and CAIs, chondrule-matrix ratio, and mineral chemistry. Petrologic type 3 based on the chemical variability of olivine and pyroxene. | ||||||||||||||||||||||||||||||
