  • PSRD:: Discovery of hapkeite

    www.psrd.hawaii.edu/July04/newMineral.html Hapkeite is the third iron silicide identified in this lunar meteorite. The other two minerals remain to be formerly named, FeSi and FeSi 2 . Anand and colleagues consider SiO 2 in the vapor phase from energetic impact-induced melts to be an important source of SiO 2+ and Si 0 , which would combine in various proportions in the vapor with Fe 0 ...

    www.ncbi.nlm.nih.gov/pmc/articles/PMC406430 We report here the natural occurrence of the mineral hapkeite, a Fe 2 Si phase, and other associated Fe-Si phases (iron-silicides) in a regolith breccia clast of a lunar highland meteorite. These Fe-Si phases are considered to be a direct product of impact-induced, vapor-phase deposition in the lunar soil, all part of space weathering.

    www.assignmentpoint.com/science/.../hapkeite-properties-and-occurrences.html 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. Due to its 1:2 composition of silicon-iron, hapkeite was given the chemical formula Fe 2 Si. It is a meteoric mineral composed of silicon and iron.
