NWA 8330 is an LL3 chondrite that was recovered out of the Saharan Desert in Morocco in 2014. It is a single-stone meteorite, with only about 500g remaining after classification. It is loaded with tiny chondrules and even small pieces have chondrules visible under a loupe. It is mildly shocked at S1 and moderately weathered at W3.

From the Meteoritical Bulletin entry on NWA 8330 :

Northwest Africa 8330 (NWA 8330)


Purchased: Jan 2014

Classification: Ordinary chondrite (LL3)

History: Purchased from a dealer in Morocco in 2014 by Aras Jonikas

Physical characteristics: One brown partially fusion crusted stone, cut surface reveals many very closely packed chondrules of various sizes and colors.

Petrography: (A. Rubin, UCLA) Microprobe examination of a polished mount shows the rock contains very sharply defined chondrules averaging about 600 μm in diameter; this is in the LL range. Chondrule textural types include PO, POP, PP, BO, C, RP. Many of the chondrules contain polysynthetically twinned low-Ca clinopyroxene phenocrysts. Small amounts of fine-grained silicate matrix material are present.

Classification: Ordinary Chondrite (LL3), Cr2O3 indicates that the petrologic type is >3.2, the absence of isotropic glass suggests that the petrologic type is >3.5.
