CK3 & CR2 炭質コンドライト セット - 16.38 g

Offered for sale is a set of three different rare carbonaceous chondrites: Erg Chech 003 (CR2): 7 grams (very small fragments, in a cylindrical flask) + 2.41 grams (3 small fragments, in a small round box). Erg Chech 003 represents far more than an uncommon meteorite. Its combination of rarity, scientific significance (showing signs of in-situ aqueous alteration which occured on its asteroid parent body), and limited availability makes it a highly desirable acquisition for collectors who focus on primitive Solar System material. NWA 16003 (CK3): 3.28 grams. Carbonaceous chondrite (CK3). The Cr2O3 contents of magnetites are intermediate between the accepted ranges for CVox3 chondrites and CK3 chondrites. The presence of unusual polymineralic clasts not present in either of those meteorite groups is noteworthy. This material is almost certainly paired with NWA 16009 based on the very similar textures, mineral compositions and especially the presence of unusual, texturally and mineralogically very distinctive polymineralic clasts. NWA 14596 (CK3): 3.70 grams Cut surfaces show a gray matrix bearing large chondrules and some CAIs. In thin section, chondrules (15 vol%), calcium aluminum-rich inclusions (15 vol%) and amoeboid olivine aggregates (5 vol%) all bear dark fine-grained rims, well spaced in a dark fragmental matrix. Chondrules of dominantly POP, BO types average 910±424 µm (n=24) diameter, and typically have igneous rims. Several round dark inclusions ranging from 150 to 800 µm are also present, bearing fine magnetite-rich rims. Olivine in chondrules and martix shows sharp to undulatory extinction. Olivine in the matrix appears pitted with cloudy cores. No metal is present. Spongy textured magnetite occurs as small grains, isolated spherical aggregates in matrix and as grains in rim material and inclusions within chondrules. Troilite appears on some chondrule rims and as blocky isolated grains in the matrix. In BSE images, chondrule olivine grains are typically zoned to Fe-rich rims. I am a member of the Meteoritical Society (#7743) and have been collecting meteorites for more than 15 years.
