Polimineralne nodule w gruboziarnistym meteorycie Morasko

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.
