Opis:: On 21 of July 2001, small fragment of metal has been found on side walk, near branch of Silesian University in Cieszyn, by Ms. Małgorzata Kotowiecki. After a few years, the metallic fragment was carefully study. The investigation show that the metallic element has meteoritic origin. The mineral composition of the meteorite (kamacite, taenite, tetraenite, troilite, daubreelite) classify it as an iron meteorite and the most probably is representative of octahedrite. The meteorite has features of shock metamorphism and represent very old fall. It could be supposed that the meteorite has been transported to the destination place, together with gravel.

Opis:: Morasko meteorite (IAB octahedrite) contains numerous graphite-troilite inclusions. Within these inclusions, many mineral phases have been found, including native elements, sulphides, tellurides, oxides, phosphates and silicates. Apart from dominant graphite and troilite, the following minerals occur: copper, sphalerite, daubreelite, chromite, cosmochlor, enstatite, albite and orthoclase; phosphates (buchwaldite and brianite) are found occasionally, whereas djerfischerite, altaite, olivine and silica are rare. The mineral composition of the nodules suggests a more complex origin of the Morasko-type meteorites than currently assumed.

Opis:: 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.
