CM2 VERY RARE, Only 910 grms in the World NWA 12917. End Cut - 6.47 g

This is one of the most fascinating, coveted and hard-to-find carbonaceous meteorites CM carbonaceous chondrites are distinguished by small refractory concretions and inclusions (0. 3 mm) , abundant fine-grained matrix (70 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 has been found, that is, before the formation of our own planet, and even our Solar System. Carbonaceous chondrites account for about 4% of all meteorites CMs have often been described as ‘the most studied meteorite in history’. This specimen is a thin slice, showing the interior of the meteorite and the fusion crust. They have been found to possess surprising and unknown catalyst properties. Its minerals can 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 https: //www. lpi. usra. edu/meteor/metbull. php? sea=carlos&sfor=text&ants=&nwas=&falls=&valids=&stype=contains&lrec=50&map=ge&browse=&country=All&srt=name&categ=All&mblist=All&rect=&phot=&strewn=&snew=0&pnt=Normal%20table&code=70607&fbclid=Iw.
