NWA 859 – Taza

Iron ungrouped
Complete specimen, 3200g
Size: 20,0 x 9,5 x 7,0 cm

The Taza meteorite is officially known as NWA 859. The texture of the meteorite is quite unusual: it is a “plessitic octahedrite” consisting of elongated spindles of the low-nickel iron mineral kamacite residing in a groundmass of a fine-grained intergrowth of kamacite and taenite (the high-nickel iron mineral) known as “plessite.” Although the surfaces of many specimens are reddish, some have preserved flow lines and patches of dark fusion crust. The interiors of most samples are fresh and unweathered.

In just a short time frame the strewnfield was defined and worked out with relatively no new discovereies since late 2012.It was found in Morocco in 2001. Many of the specimens of this meteorite are oriented in shape from falling through the atmosphere in a stable flight. One surface ablated away and melted material flowed to the back and cooled there leaving flow lines and melted lips. Most pieces of this meteorite are small with hundreds having been recovered. The main mass however is a 75.3 kg piece.
