The NWA 869 chondrite is the largest known rock fall, making it one of the most famous falls Magnificent piece in which we can see a primary fusion crust Chondrites are the oldest materials in the Solar System, with an estimated formation age of 4,550 million years. They are meteorites that have not been differentiated, and because they contain iron, in this case, in low quantity, that they are type L Most of them come from the asteroid belt located between Mars and Jupiter The characteristic of chondrites is the presence of chondrules, small balls of millimetres in size, largely composed of silicates. The standard model for its initial formation is that they occur during the condensation of the solar nebula, of the cosmic dust. The chondrules are considered to be the first elements from which the planets are formed. At Expometeoritos, we take care of the dissemination, talks, workshops, analysis, classification and exhibitions of Meteorites. We are members of: .- IMCA (International Meteorite Collectors Association) #8187 .- Meteoritical Society .- American Meteor Society All our pieces are certified and we also deliver the analysis of the chemical composition if the value of the piece exceeds €300, carried out in our facilities by X-ray Spectrography.
