Abstract

Northwest Africa 14897 is a meteorite purchased in 2017 at Erfoud, Morocco. The main mass, weighing 262 g and owned by Abdeltif Mechaguen, is covered by a dark brown fusion crust. The type specimen, weighing 36 g, and one polished thin section is on deposit at MSN-Fi (Inv.# I3690); one polished section is at the University of Bari. A cut surface shows a dark brown, homogeneous interior. No metal spots are visible on the cut surface, probably due to the marked alteration. A classification as LL7 ordinary chondrite has been proposed based on texture and chemistry.
