Hapkeit
Sign in to saveAlso known as IMA2003-014
Hapkeite is a mineral discovered in the Dhofar 280 meteorite found in 2000 in Oman on the Arabian Peninsula. The meteorite is believed to originate from the Moon; specifically, it appears to be a fragment of lunar highland breccia. Hapkeite's composition is of silicon and iron, and it is similar to other silicon-iron minerals found on Earth. An impact on the Moon is thought to have launched the partially molten or vaporized material into orbit.

Hapkeit är ett mineral som hittats på en meteorit från månen. Mineralet bildas då järn och kisel fälls ut med två delar järn och en del kisel, Fe2Si. Namnet kommer från den amerikanske professorn som förutsade[när?] en sådan upptäckt.
