Description
Hello up for auction is an extremely rare and stunning Lunar known as NWA 13992 and classified as a Polymict Fragmental Lunar Breccia aka "HARVAST MOON" for its deep orange basaltic clasts. This beautiful individual weighs 14.770 grams is has an awesome shape, beautiful colors, comes with COA card and display case. Electron microprobe analysis of a polished mount shows this meteorite to be a lunar polymict breccia with at least two distinct lithologies.Lithology 1: this is
feldspathic breccia
consisting of fragments of olivine and pyroxene, and anorthitic plagioclase, with accessory phases Fe,Ni-metal, Fe-sulfide, ilmenite, and chromite.
Lithology 2: this
is a
basaltic textured domain
with intergranular pyroxene and plagioclase grains that grades into a partially shock melted pyroxene cumulate textured domain, with minor barite, Fe-sulfide, ilmenite, and silica -- olivine is absent. This is very exciting the Lunar Basalt is extremely rare and expensive. I have been very lucky to aquire 420 grams of this insane looking material from my friend Douglas Chenin. The pieces are shiny, irregular shaped, sandblasted exteriors with patches of two colors, dark brown and light brownish-yellow, representing the main lithologies in these meteorite samples. I will have some bigger slices available in a few days. Thanks for your interest and take care! This is very rare material and limited supply of just over 1 kilo and most is sold. I have 400 grams available and I will be selling it slowly.
1 of 7 ever approved, DUAL LITHOLOGIES!!!
