NWA 2945
Found 2005mesosiderite
10 Kg largest mass 1080g
Description and (paired with NWA 2923 per T. Bunch of NAU )
classification (T. Bunch and J. Wittke, NAU): a fine-grained (<0.5 mm)
matrix that consists of brecciated and partially recrystallized
subophitic to granular basalts and encloses larger (up to 2.5 mm)
subrounded to subangular olivine (Fa28) and pigeonite (Fs31Wo5.4;
Cr2O3 = 0.87 and Al2O3 = 1.28 wt %; FeO/MnO = 25.7) that rarely shows twinning.
These cataclastic basalts contain unusually calcic plagioclase
(An99.3) with little FeO (<0.04 wt %); highly twinned pigeonite
is compositional similar to the much larger clast pigeonite (Fs32Wo5.7),
but with very little Cr2O3 and Al2O3; merrilite is also present.
Metal (Ni = 6.6 wt % ) is irregular in shape and typically
< 2 mm in size with the exceptions of metal aggregates and rare,
cm sized metal nuggets with included pigeonite and cataclastic matrix.
Weathering grade is variable and dependent on the specimen size.
