卖家的描述
Northwest Africa 14680 (NWA 14680)
Purchased: 2021 Nov
Classification: Ordinary chondrite (LL3)
Petrography: (K. Metzler, IfP) Unequilibrated ordinary chondrite, consisting of closely packed chondrules and chondrule fragments, with low amounts of interchondrule matrix. The mean apparent chondrule size is 580 μm (n=160). Small amounts of Fe-Ni metal (partly terrestrially oxidized) and troilite, mostly residing outside of chondrules.
Geochemistry: Mineral compositions and geochemistry: The mean olivine composition is Fa14.7±11.0 (Fa1.0-42.6; n=24); the mean low-Ca pyroxene composition is Fs8.7±6.6Wo1.0±0.8 (Fs1.5-20.9Wo0.3-2.5; n=18).
Classification: LL chondrite, based on the low metal content and large mean apparent chondrule size. Petrologic type 3, based on the chemical variation of olivine and pyroxene. Petrologic subtype based on the high PMD of Fa values (PMD=75).
Specimens: The largest stone has a weight of 1194 g.
Shock stage: C-S1
Weathering grade: W3
Classifier: K. Metzler, IfP.
This lot comes with certificate of authenticity.
