Meteorite**NWA 15349; Lunar Frag Breccia**173.80 gram Individual, W/Fusion Crust

Description

Hello up for sale is the
MAIN MASS
to NWA 15349
[Provisional]
classified as a Lunar Fragmental Breccia and NEW FIND!! This gorgeous Main Mass individual weighs 173.80 grams, and was broken in flight, two pieces fit together perfectly, it's amazing both pieces were found. The bigger piece weighs 107.9 grams and the smaller piece weighs 65.9 grams, with a polished face on one side so you can see the amazing brecciated matrix. The Exterior is covered in fresh, green, glassy fusion crust with very fresh look!!! The 65.9 gram piece had about 5 slices taken off and a 14 grams sample submitted for classification with UNM. The Saw-cut surface reveals a breccia with light and dark colored clasts set in a dark gray groundmass. Reflected light microscopy and electron microprobe analysis indicates a lunar fragmental breccia with lithic clasts, mineral clasts, and vesicular shock melt pockets. Major phases are plagioclase, clinopyroxene with lesser amounts of olivine. Minor phases include low-Ni iron metal, ilmenite, troilite, chromite, silica and Ti-Cr spinel. This meteorite comes with a COA card and display case. Thanks for your interest and take care.
Note: This Lunar meteorite is Provisional,
it's
waiting for approval from the nom com,
it's
already been officially analyzed. This is a brand new find and one of the most beautiful Lunars on the market, extremely fresh with fusion crust!!!
