Description
Hello up for sale is my newest classification NWA 13907 Rare Lunar Ferroan Anorthosite (FAN) found near Adrar, Algeria 2020, oldest known lunar material. This gorgeous mini slice weighs 0.267 grams and has a extra fine polish to both sides, Lunar ferroan anorthosites are generally thought to be relics of the Moon's primordial crust, formed by flotation and accumulation of plagioclase atop a differentiating, Moon-wide magma ocean, very ancient lunar.This slice was cut with a wire saw by Steve Arnold of meteorite men the TV show. Microprobe examination reveals an anorthitic plagioclase host making up 90-95% of this meteorite. Poikiolitically enclosed in the plagioclase are sparse, small olivine and pyroxene grains (most in the size range 100-200 m). Larger pyroxene grains are scarce with one larger grain in size range of 1 mm observed in the microprobe mount. Together, olivine and pyroxene make up a total of ~5% of this meteorite This lot comes with a high quality display case and COA card from me streamingmeteorites! Thanks for your interest and take care! This was from the same find as Touat 005, if i sold you a piece its been classified as NWA 13907. If you want a new COA card just send me a message, this is a rare type of Lunar from the Highlands, oldest known Lunar and possibly from the far side of the moon!!!ALMOST OUT OF STOCK!!!
