2021年2月18日 · The extended X-ray absorption fine structure (EXAFS) analyses of NWA 859 and a single-crystal diffraction of tetrataenite show that it has a near-face-centered cubic (FCC) tetragonal structure with 12 nearest-neighboring Ni, Fe, and Ge atoms at distances of rNi-(Ni, Fe) = 2.5170(13) Å, rFe-(Ni, Fe) = 2.534(3) Å, and rGe-(Ni, Fe) = 2.524(5) Å ...

NWA 859又名“Taza”陨石。2001年发现于摩洛哥Taza地区，总质量75.3 kg。Taza陨石已被摩洛哥当地政府保护，图1为典型Taza陨石标本。

Taza陨石国际命名NWA 859,国内称其“塔扎”，因2001年在位于西北非摩洛哥的Taza地区发现而得名。Taza陨石之所以在铁陨石中售价一直很高，与它特有的以下几点因素相关： 在大多数铁陨石群的发现中，铁陨石的收集量…

2021年2月11日 · The Taza meteorite (officially designated as NWA 859) is a nickel–iron meteorite classified as a Plessitic Octahedrite, Ungrouped.

The Taza meteorite (NWA 859) is a rare Saharan Iron that was first discovered in Morocco in 2001 near the town of Taza. It is very stable and renowned for it gorgeous sculpted appearance and stunning fine star-like Windmanstatten patterns.

NWA 859, small individuals, 1 slice, 1 endcut quantity. Known also by the official name NWA 859, Taza meteorite is classified as an ungrouped plessitic octahedrite iron. It was found in Morocco in 2001 near the city of Taza but in a undisclosed location, so it was given a NWA number.
