An original classification from the Natural History Lab, this is an AMAZING L3 chondrite! Exquisitely prepared in-house, this full slice is packed with chondrules. This is the last slice remaining!
Size: 74mm x 44mm x 3mm
Petrography: (A. Irving and S. Kuehner, UWS) Closely-packed, well-formed chondrules (apparent diameter 500±400 µm) are set in a sparse fine grained, black matrix.
Geochemistry: Olivine (Fa1.2-49.9, Cr2O3 in ferroan examples 0.08-0.23 wt.%, mean 0.16±0.05 wt.%, N = 8), orthopyroxene (Fs1.9-6.7Wo0.4-2.3, N = 3), pigeonite (Fs39.1Wo5.9), subcalcic augite (Fs8.9-14.2Wo36.7-32.0, N = 2).
