CR2 NWA 13880 Condrite carboniosa con crosta di fusione - 110 g

It is one of the most fascinating, coveted and hard-to-find carbonaceous meteorites The CR group of carbonaceous chondrites is distinguished by large and abundant chondrules, many of which are igneous, few refractory inclusions, abundant metal (5-8 vol%) and a commonly hydrated fine-grained matrix (up to 50 vol%) and abundant hydrocarbons as well as amino acids It makes them the oldest known material on Earth, although recently material from 7 billion years ago was found, that is, before the formation of our own planet, and even our Solar System. Carbonaceous chondrites account for about 4% of all meteorites This specimen is a sheet showing the inside of the meteorite They have been found to possess surprising and unknown catalyst properties. Its minerals are able to synthesize, in an aqueous dissolution and in the presence of formamide, key organic compounds in prebiotic chemistry. Such catalyst properties point to the fundamental role in the origin of life on our planet and, why not, anywhere else in the Universe At Expometeoritos, we take care of dissemination, talks, workshops, analyses, classification and exhibitions of meteorites. All our pieces are certified and, if the value of the piece is over €300, we also provide its chemical composition analysis, carried out in our facilities by X-ray spectrography.
