Northwest Africa 14613
Purchased: Feb 2018
Classification: Ordinary chondrite (H5)
Purchased by the Aerolite Meteorites team in 2018 from a Moroccan dealer, NWA 14613 is classified as an H5 chondrite. A dark exterior offsets light grey chondrules revealed in its interior when cut and polished. The parent body of H chondrites is yet unknown, but scientists have pinpointed S-type asteroid 6 Hebe as a possible candidate, with less likely candidates being 3 June and 7 Iris. Of particular note is that H chondrites overall have similar trace element abundances and oxygen isotope ratios to IIE iron meteorites, indicating that they may have originated from the same parent body.
