The carbonaceous or "C" chondrites are some of the most unchanged materials known, and their chemical compositions match more accurately the chemistry of the Sun than any other kind of chondrites.
Carbonaceous chondrites are primitive and undifferentiated meteorites that were formed in oxygen-rich regions of the early Solar System so most of the metal is not in its free form, but as silicates, oxides or sulphides.
Most of them contain water, or minerals that have been altered in the presence of water, and some of them contain large amounts of carbon, as well as organic compounds.
Carbonaceous chondrites contain amino acids and water in their composition, being perhaps the most amazing meteorites scientifically speaking that we can have in our hands, since the latest studies suggest that they were the ones that sowed life on Earth, with their amino acids and high carbon content
They are very scarce, barely representing 4.8% of the meteorites found, so they rarely go on sale.
Chondrites are the oldest material in the Solar System, having an estimated formation age of 4,550 million years.
The characteristic of chondrites is the presence of chondrules, small balls of millimetres in size, largely composed of silicates.
The standard model for their initial formation is that they occur during the condensation of solar nebula, of cosmic dust.
At Expometeoritos, we take care of dissemination, talks, workshops, analyses, classification and exhibitions of meteorites.
