Toutes les enchères / Ethnographie / CK Carbonaceous Chondrite METEORITE
Much less common than their ordinary chondrite sisters, carbonaceous chondrites represent 5% of the meteorites that reach Earth. They are characterized by the presence of carbon in their composition—hence their name—generally in the form of organic compounds such as amino acids. In addition, carbonaceous chondrites usually contain water or minerals that indicate they have been altered by its presence. With a dark and generally abundant matrix, they are the oldest meteorites known and therefore the oldest material you will ever be able to hold in your hands. CK meteorites are carbonaceous chondrites with a matrix in dark gray tones, sometimes slightly greenish, with abundant chondrules that can range from type 3 to 6, with an average diameter of 1 mm, i.e., somewhat smaller than CVs and larger than COs (the family of carbonaceous chondrites with which they are related). Sometimes they contain CAIs of considerable size. Additionally, some CK members display shock veins that indicate a violent history for their parent body or a history of impact. Moreover, the specimen from this lot has a nice shape and size, and fusion crust on much of its exterior, something difficult to find in this type of carbonaceous chondrites. Ideal for a great collection or museum. All our meteorites come with an IMCA certificate (International Meteorite Collectors Association) therefore we guarantee the authenticity of all our meteorites for life. Buy with confidence. Best regards and our best wishes. CRATER METEORITES
