Лот 64 | LARGE FORMAT MESOSIDERITE COMPLETE SLICE — NWA 15346
Оценочная стоимость
$ 10 000 – 15 000
NWA 15346 was found in 2020 and is exceedingly fresh. The exterior rim of the specimen exhibits a desert varnish. The cut surface reveals pervasive fine-grained metal and sulfide inclusions and a bounty of dark fine-grained silicates. Scattered larger silicates accent this otherworldly abstraction. The silicates are primarily comprised of pyroxene with a bit of plagioclase and trace amounts of silica, merrillite, chromite and schreibersite. Segregated metal and some brecciation is in evidence. All of the aforementioned result in NWA 15346 — the 15,246th meteorite from the North West African grid of the Sahara to be recovered, analyzed, classified and published — being assigned a B2 classification. While mesosiderites represent less than 0.5% of all meteorites, the B2 class is more rare still: of the 316 documented mesosiderites, only nine are designated B2. Moreover, NWA 15346 is the 11th largest mesosiderite on record and now offered is among the largest complete slices of a mesosiderite available — a large format example of an exquisite, enigmatic meteorite.
