» Meteorite: NWA 5206

Northwest Africa 5206
Algeria
Find: 2007
Classification: Chondrite LL3.05 !!!!

History and physical characteristics:
A 1276g desert-weathered, brownish stone was purchased in Erfoud, Morocco in October 2007.
Petrography (J. Wittke and T. Bunch, NAU):
Contains a magnificent collection of closely packed, pristine chondrules. All varieties of chondrules are represented with Type I (FeO - poor) dominant over Type II (FeO-rich) by a ratio of 3:1. The abundance of chondrule textural types are PP > PO > POP > GOP > RP > C > R > BO with several heavily mantled and unique types. SEM imagery and x-ray mapping show no evidence of devitrification in chondrule mesostasis, mostly homogeneous mesostasis, and alkali-poor mesostasis compositions. Weathering grade is W3 with minor iron staining in thin section.
Mineral compositions:
Cr2O3 content in olivine is consistent wit a classification of < subtype 3.1. Until high quality analyses are performed on chondrule mesostasis for K and Na contents and distributions, a 3.0 subtype is not warranted at this time.
