The NWA 13758 meteorite was found in 2017 on the Tanezrouft Plateau in North Africa. A large group of meteorites were recovered from the same location which appeared identical. NWA 13758 is a type three Rumuruti chondrite (R3). Approximately 500 pieces of the meteorite were found ranging in size from less than one kilogram to greater than five kilograms. Rumuruti meteorites as a group are special by their lack of iron metal. NWA 13758 was classified with a shock stage of S2 and a weathering grade of W1. A large proportion of Rumuruti meteorites are brecciated and that is the case with NWA 13758.
NWA 13758 has a dark exterior which has been scoured by sandblasting. A brecciated structure is seen in these meteorites which shows two distinct lithologies one gray and the other brownish-orange. Abundant chondrules can be seen in NWA 13758. As is typical of Rumuruti type meteorites no metal or oxidized iron was found in NWA 13758.
