Silicon   Moissanite

Comments: Backscattered electron image of metallic inclusion in moissanite (SiC). The gray shading in the BSE mage consists mainly of pure silicon (Si metal). The brighter areas are composed of Fe-silicide. (AmMin, 88:1818).
Location: Found in a cobble at a beach along the Turkish coast of the Mediterranean Sea, around 150 km NW from Izmir, and is most likely derived from Tertiary volcanic rocks outcropping in the area. Scale: Scalebar 200 µ-m.
