英文摘要	Halamishite, Ni5P4, is a new natural phosphide discovered in pyrometamorphic assemblages of the Hatrurim Formation (Mottled Zone), Southern Levant. The mineral occurs as minute grains up to 20 mu m in size intimately intergrown with zuktamrurite, FeP2, and transjordanite, (Ni,Fe)(2)P, which are disseminated in fine-grained diopside microbreccia. Chemical composition of the holotype material (electron microprobe, wt%): Ni 69.23, Fe 1.80, P 29.59, total 100.62, was recalculated to (Ni4.90Fe0.13)(5.03)P-3.97 on the basis of nine atoms per formula unit. The ideal formula of halamishite is Ni5P4. In reflected light, the mineral is white with beige tint, non-pleochroic. It is moderately anisotropic and bireflectant (Delta R-589 = 7.2%). Reflectance values for the four wavelengths recommended by the IMA Commission on Ore Microscopy are [R-max/R-min (%), lambda (nm)]: 44.3/36.6, 470; 49.2/42.1, 546; 51.3/44.1, 589; 53.3/46.1, 650. Crystal structure of halamishite was solved and refined to R-1 = 0.031 based on 425 unique observed [I >= 2 sigma(I)] reflections. The mineral is hexagonal, space group P6(3)mc, a 6.8184(4), c 11.0288(8) angstrom, V 444.04(6) angstrom(3), Z = 4. D-x calculated for an empirical formula is 6.249(1) g cm(-3). Halamishite is named for its type locality, the Halamish wadi in the Hatrurim basin, Negev Desert, Israel. It is a naturally occurring analogue of synthetic Ni5P4, the compound widely used in electro- and photocatalytic applications. Due to chemical proximity to the Ni5P4 end-member, halamishite can be used as a geothermometer indicating that formation of phosphide assemblages had occurred at a temperature below 870 degrees C.
