{"title":"NWA 12671 - CK6 Carbonaceous Chondrite","description":"\u003cp\u003eNWA 12671 is a CK6 Carbonaceous Chondrite purchased in 2018 after recovery from Northwest Africa. CK Chondrites are named after the Karoonda meteorite and represent Carbonaceous material that has generally experienced more thermal alteration than many other Carbonaceous groups. As a type 6 specimen, NWA 12671 records significant recrystallisation on its parent body, while still preserving the broader chemistry of primitive early solar system material. The Meteoritical Bulletin records NWA 12671 as an approved CK6 Carbonaceous Chondrite.\u003c\/p\u003e\n\u003cp\u003eNWA 12671 specimens are typically dark grey to black, often with a compact, recrystallised texture. Chondrules are generally rare or subdued due to the high level of thermal metamorphism, while the interior is dominated by fine-grained material rich in ferrous olivine and other mineral phases. Some fragments may retain partial fusion crust, adding contrast to the darker matrix and reflecting the meteorite’s atmospheric entry before recovery.\u003c\/p\u003e\n\u003cp\u003eStudying NWA 12671 provides insight into the effects of heat on Carbonaceous parent bodies, especially how primitive material can be altered while retaining a Carbonaceous chemical identity. For collectors, it offers a distinctive example of a highly metamorphosed Carbonaceous Chondrite with a recognised classification and Northwest African provenance. Each specimen represents ancient asteroid material that preserves both early solar system chemistry and later thermal evolution.\u003c\/p\u003e","products":[{"product_id":"nwa-12671","title":"NWA 12671 - CK6 Carbonaceous Chondrite - Fragment - 0.436g - Northwest Africa","description":"\u003cp data-start=\"26\" data-end=\"499\"\u003eNWA 12671 is a CK6 Carbonaceous Chondrite purchased in 2018 after recovery from Northwest Africa.
