Moss CO3.6 Carbonaceous Chondrite Meteorites for
Sale
Location: Moss, Østfold, Norway, 59° 26'N, 10° 42'E
Fell: 2006, July 14, ~10:20 hrs local daylight time
Type: Carbonaceous chondrite (CO3.6)
Description: History and physical characteristics: (G. Raade and K. Ødegaard, UOslo; M. Bilet, NorAS) At about 10:20 am on July 14, 2006, a bright fireball traveling SSE-NNW was witnessed by many people and a loud explosion and a rumbling sound was heard in the air above Moss and Rygge in south Norway, on the east side of the Oslofjord. Shortly after, a small meteorite was heard to land on an aluminum sheet and was recovered. Extensive searches in the area have resulted in the recovery of a total of 5 stones (Table 6). Note that light rainfall occurred in the area on July 29, 30, and 31.

M-S-T: Mass divided between Michael Mazur, Bjørn Sørheim, and Eric Twelker.
Petrography: Contains abundant small chondrules (most < 200 μm), small (<1 mm) amoeboid olivine aggregates (AOAs) and refractory inclusions, and isolated grains of olivine, troilite, and kamacite set in a gray matrix. Chondrule types are dominated by type-I PO, with other varieties of type I and II chondrules plus RP, C, and BO all present. All type I chondrules show diffusional entry of FeO around edges and along cracks of forsterite grains. Olivine histogram is flat, resembling that of Ornans (range Fa0.3–42, average Fa19.9, σ=65%, n=60); Cr2O3 content of fayalitic olivine is low (0.09±0.09 wt%). Image analysis gives 2.2 vol% metal and 2.4 vol% FeS. Refractory inclusions contain spinel, calcic pyroxene, and abundant nepheline that replaces melilite and other primary phases; some perovskite has been transformed to ilmenite. Some AOAs contain relict cores of forsterite, but most of the olivine has been converted to more fayalitic compositions; degree of oxidation of AOAs is similar to type 3.6 CO chondrites such as ALH 77003. Matrix is mildly recrystallized and sulfur-poor; matrix olivine has similar composition to olivine in fine-grained chondrules and inclusions. Geochemistry: Magnetic susceptibility (R. Bartoschewitz), log χ (10-9 m3·kg-1) = 4.68. Oxygen isotopes (I. Franchi and R. Greenwood, OU), average of two replicates, δ17O = ‑5.90‰, δ18O = ‑2.21‰, Δ17O = ‑4.75‰. Classification: Carbonaceous chondrite (CO3.6, scheme of Chizmadia et al., 2002); shock stage S2.
