Carbonaceous chondrite meteorites. In an exciting time of scientific discovery meteorites like the Tarda provide a time capsule of carbon bearing materials from the early solar system. Carbonaceous chondrites come from very diverse locations in our Solar System. Later the amino acid alanine, which is also a protein amino acid, was found to have an excess of the L-configuration,[11] which led several scientists to suspect terrestrial contamination according to the argument that it would be "unusual for an abiotic stereoselective decomposition or synthesis of amino acids to occur with protein amino acids but not with non-protein amino acids". [2], In January 2020, cosmochemists reported that the oldest material found on Earth to date are the silicon carbide particles from the Murchison meteorite, which have been determined to be 7billion years old, about 2.5billion years older than the 4.54-billion-year age of the Earth and the Solar System. It includes amino acids, diamino acids, dipeptides, hydrocarbons, alcohols, carboxylic acids, diketopiperazines, sulfonic and phosphonic acids, purines, pyrimidines, sugars and sugar-related compounds, amines, amides, The Murchison and Lonewolf Nunataks 94102 meteorites contained a diverse suite of nucleobases, which included three unusual and terrestrially rare nucleobase analogs: purine, 2,6-diaminopurine, and 6,8-diaminopurine.

[21], Measured purine and pyrimidine compounds were found in the Murchison meteorite. A specific family of amino acids called diamino acids was identified in the Murchison meteorite as well. Meteorites provide a record of the chemical processes that occurred in the solar system before life began on Earth. [6] Like other CM chondrites, Murchison contains abundant calcium-aluminium-rich inclusions. Some stone meteorites, known as carbonaceous chondrites, have been found to contain water, salt, and even amino acids. 2011 Aug 23;108(34):14015-20. doi: 10.1073/pnas.1105715108.

The rare CR2 group of stone meteorites is represented by about 160 different examples, over half of which were found in Antartica and are, therefore, not available to collectors. This is a very interesting and complex group of chondrites and has many subgroups. The Alais CI1 Carbonaceous Meteorite. The CI1 and CM2 carbonaceous meteorites are likely the fragments of spent comets, which are largely made of water-ice with regions on their jet-black surface that get very hot (~400 K for Halley at 0.8 AU) as their orbit carries them closer to the Sun than Earth is. The Flensburg meteorite fell to Earth on September 12, 2019, in an event observed by hundreds of eyewitnesses from the Netherlands, Belgium, Germany, Denmark, and the United Kingdom. Due to its mass (over 100kg or 220lb) and the fact that it was an observed fall, the Murchison meteorite is one of the most studied of all meteorites. Acrobat Distiller 6.0.1 (Windows) Carbonaceous chondrite (CC) meteorites such as the Murchison meteortite have 10% or more carbon, while cometary dust has a 30% CHON particle fraction (made of the light elements C,H,O,N) as well as mineral particles and particles of mixed composition, as discovered by the comet Halley space-probes.
Type 3.00 meteorites are extremely rare. They have a charcoal-like appearance due to their high concentration of carbon. The organic composition of carbonaceous meteorites: the evolutionary story ahead of biochemistry.
