NWA 7319 is a stunning L5 Melt Breccia chondrite with a shock stage of 6 and weathering grade of 1.
The Total Known Weight is 6414 grams in a single stone purchased in Morocco in April 2012. It displays
gorgeous melt "rivers" enveloping "islands" of matrix with a nice amount of large and small vesicles, all covered with smallish metal flakes. The large slices offer a very generous size-to-weight ratio meaning that you get more display surface to the weight investment!
The fresh interior shows dispersed clasts of chondrule-bearing material within more abundant fine-grained,
black material containing ellipsoidal metal+sulfide grains. Some regions contain sparse chondrules with
moderate amounts of metal, but the predominant lithology is composed of very fine grained olivine, pyroxene
and rounded grains of intergrown kamacite+troilite. The geochemistry consists of: Olivine (Fa23.7-23.8
), orthopyroxene (Fs19.7-20.6
The majority of NWA 7319 is made up of the 4120 gram main mass which is curated in a private collection. I have listed all that is available here!
