Atacamaite #4 – 0,2 g
5,94 $
The Atacamaites were discovered in the Atacama desert in Chile.
They are black and glassy objects of about 1 cm, they were formed following an impact about 7.8 million years ago.
Their small size, heterogeneity, state of oxidation and level of contamination distinguish them from tektites, which is why a study conducted by J. Gattacceca, Bertrand Devouard, Jean-Alix J-A Barrat, Pierre Rochette, M.L. Balestrieri, G. Bigazzi, G. Ménard, F. Moustard, E. dos Santos, R. Scorzelli, proposes to name them “tektoids”.
The impactor was an iron meteorite, most probably of the IIAB group.
