On Offer: 16.08g of NWA 6138, LL3.7 chondrite meteorite.

Official Name: Northwest Africa 6138

Abbreviation: NWA 6138

Type: LL3.7

Year found: 2002

Country: Northwest Africa

Low TKW: 79.3g

Description: This is an exceptional 16.08g specimen of NWA 6138, a very low metal (LL) type 3 (3.7) ordinary chondrite. There was only 79.3 grams of this meteorite classified, and this piece represents ~20% of the known mass of the NWA 6138 meteorite. This is a nearly complete individual with a small window cut on one side exposing the interior. The window shows an unusually large chondrule taking up a large part of the window, set against many much smaller well delineated chondrules. The overall macro texture and color of this LL chondrite is very similar to many CR chondrites I have encountered. I suspect this is due to a post accretion oxidation / hydration event (*no aqueous alteration reported), either on its parent body, or after it landed on Earth.

What you get: 16.08g of NWA 6138 as shown, Membrane Storage/Display Box, & signed Certificate of Authenticity.

We offer a 100% no questions asked 30 day return policy.
