Writeup history : The meteorite was purchased from a local meteorite dealer in Niger.
Writeup physical : Dark brownish rock without fusion crust.
Writeup petrog : The meteorite is an enstatite achondrite predominantly composed of 50-1000 µm sized enstatite and less abundant sodic feldspar grains. Some regions appear to be recrystallized exhibiting triple junctions. Albitic and Si-rich melt inclusions are ubiquitous throughout the meteorite. Opaque phases include nodules composed of niningerite and Cr-rich troilte, Si-rich kamacite, and rare Zn-bearing daubréelite. Metal grains are often spherical. No relict chondrules have been observed.
