Where are carbonaceous chondrites found?

It is thought they have not been heated above 50 °C (122 °F), indicating that they condensed in the cooler outer portion of the solar nebula. Six CI chondrites have been observed to fall: Ivuna, Orgueil, Alais, Tonk, Revelstoke, and Flensburg. Several others have been found by Japanese field parties in Antarctica.

Where do carbonaceous chondrite meteorites come from?

Most carbonaceous chondrites are thought to come from the low-albedo, C-type asteroids, which are the most abundant type between 2.7 and 3.4 AU (Bell et al., 1989), CM chondrites may be derived from an altered C-like asteroid called G-type (Burbine et al., 2002).

Where was the chondrite meteorite found?

The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua. After breaking up in the atmosphere, an extensive search for pieces was conducted and over 2 tonnes (tons) of meteorite were recovered.

Where can I find chondrites?

Most Chondrites are believed to originate in the asteroids that orbit the Sun between Jupiter and Mars. Chondrites contain between 2 and 21 percent iron-nickel metal. Chondrule (n) Millimeter-sized mineral spheres found in stony chondrite meteorites.

How much is a carbonaceous chondrite meteorite worth?

Carbonaceous chondrites fetch about $8 per gram and up. The rare achondrites begin at $10 to $12 per gram for a Millbillillie (a portion of the asteroid Vesta) but can go up to $700 per gram for a Zagami (from Mars), $2,500 per gram for a DAG 476 (also from Mars), and $25,000 per gram for a DAG 400 (from the Moon).

How common are carbonaceous chondrites?

The C chondrites represent only a small proportion (4.6%) of meteorite falls.

Why are carbonaceous chondrites primitive?

Composition. Because chondrites accumulated from material that formed very early in the history of the solar system, and because chondritic asteroids did not melt, they have very primitive compositions.

Are carbonaceous chondrites differentiated?

Chondrites can be differentiated from iron meteorites due to their low iron and nickel content. Other non-metallic meteorites, achondrites, which lack chondrules, were formed more recently. There are currently over 27,000 chondrites in the world's collections….
