In this paper, a new mineralogical and chemical data on a new brecciated enstatite are presented. Fe-low enstite is the main pyroxene. Locally small grains of diopside were noted. The rest of silicates are represented by oligoclase and cristobalite. Siliceous glass was also found. The meteorite contains up to11.5 vol.% of Ni-kamacite (up to 6.8 wt.% of Ni and up to 2.9 wt.% of Si). Niningeryt and Cr-rich troilite are the main sulphides. Small amount of graphite forms a bundle-like agregates of fine plate crystals. The classification is still in progres. The new meteorite from Algeria can be an example of unbrecciated enstatite or ungrouped achondrites.
