NWA 16207 - Σπάνιος ενστατίτης χοντρίτης (EL6, μισολίθος) - 42.72 g
A stunning half-stone of Northwest Africa 16207, an officially classified EL6 enstatite chondrite up for grabs.
NWA 16207 was found in 2017 and purchased in Morocco in January of that year by meteorite dealer Jasper Spencer. With a total approved mass of 1,872 grams, it was officially classified in 2023 and published in Meteoritical Bulletin 112.
Enstatite chondrites are among the most chemically distinctive primitive chondrite meteorites known. They formed under the highly reducing conditions of the early Solar System, reflected in their exceptionally magnesium-rich silicates and unusual assemblage of metal and sulfide minerals. NWA 16207 is an EL6, indicating substantial thermal metamorphism.
The meteorite has a recrystallised texture with no obvious relict chondrules, consistent with its relatively high petrologic type. Its principal minerals are enstatite, a SiO₂ phase, plagioclase, troilite and Fe-Ni metal, while many of the opaque phases show terrestrial weathering.
The offered half-stone provides an excellent representation of this unusual meteorite, exposing its recrystallised enstatite-rich interior and the characteristic opaque mineral assemblage.
I am a member of the Meteoritical Society (#7743) and the Global Meteorite Association GMA (#G0129) have been collecting meteorites for more than 16 years.
