Frontier Mountain 99030 Lodranite A flat (2 x 1.5 x 0.5 mm) metal fragment with abundant silicates; metal is predominantly kamacite and minor taenite (Ni = 7.1 and 28.9 at%, respectively); silicate areas are coarse grained (average grain size >0.5 mm) and consist of orthopyroxene (Fs12Wo3), olivine (Fa10), chromian diopside (Fs4Wo45, average Cr2O3 = 1.36 wt%), interstitial sodic plagioclase (An12–20), and minor troilite and schreibersite; the fragment is likely a sample of the large metal veins occuring in lodranites. | ||||||||||||||||||||||
