The mineral is named "hapkeitom" (hapkeite) in honor of the American Professor of Geology Bruce Hapke (Bruce Hapke), who predicted its discovery 30 years ago.

Hapkeit discovered a group of scientists led by Dr Mahesh Anand (Mahesh Anand) from the University of Tennessee (University of Tennessee) in the "lunar" meteorite found in Oman in 2000.

Find — it is an integral part of the regolith, soil inorganic Moon formed myriad impacts of micrometeorites, briefly creating a high temperature.

New mineral — a compound of iron and silicon, formula Fe2Si.

Scientists have studied in detail the crystal structure of the mineral, and know that it resembles that of a similar synthetic compound of the Earth, as well — some terrestrial minerals.

However hapkeit detected in several forms formed apparently at different temperatures and pressures.

Hapkeit — the third iron-silicon mineral found in meteorites, and after suessita perritita opened in the 1970s and 1980s.
