Gyarub Zangbo is a pallasite-type meteorite discovered in Tibet in 2020, weighing just 18 kg.
The mineral chemistry, the O and Cr isotopes of olivine and the metallic phase make this an anomalous carbonaceous pallasite.
Gyarub Zangbo appears to be a unique pallasite from a previously unrepresented asteroid in the pallasite collection.
Pallasites are unique stony-iron meteorites composed mainly of olivine and ferrous metal.
They are thought to have formed in the boundary region between the core and mantle of asteroids, inside asteroids.
Pallasites are meteorites composed of olivine crystals embedded in an iron-nickel matrix.
Pallasites are among the most aesthetically pleasing of meteorites.

History: Found by Ahmed Dich and Hssain Azmamar in January 2021. Bought by Jean Redelsperger from Zaid Oualguirah in February 2021.
Physical characteristics: Partially crusted stone with a light grey interior
Petrography: (J.Gattacceca, CEREGE) Brecciated igneous rock with mineral and lithic gabbroic clasts. Main minerals are pyroxene (some exsolved) and plagioclase with grain size in the 100 to 500 µm range. Accessory minerals: metal (to 150 µm), chromite (to 100 µm), ilmenite (to 150 µm), troilite (to 200 µm).

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.
