Abstract

The paper presents detail mineralogical and crystal-chemical characterization (refinement of the crystal structure including) of the first find of phosphide class mineral—barringerite, Fe2P, in terrestrial pyrometamorphic rocks of the Hatrurim formation, in Israel. The mineral occurs in associations of the so called «paralavas»—initially silicate-carbonate sedimentary rocks remelted during pyrometamorphic processes at temperature beyond 1000 °C but under low pressure. Topics related to genesis and crystal chemistry of barringerite are discussed within its connection with another polymorphic iron phosphide — allabogdanite (Fe,Ni)2P.

Key words: phosphide class minerals, barringerite, allabogdanite, pyrometamorphism, Hatrurime formation, Israel.
