NWA 10684 (Monomict Diabasic Eucrite Breccia)

NWA10684(165_55g)a NWA10684(165_55g)bTwo small stone fragments totaling  165.55g were purchased out of Morocco in February of 2016. A sample was sent to Dr. Anthony Irving for classification and determined to be a very fresh Monomict Diabasic Eucrite Breccia.  I prepared the slices which are ever so slightly polished (they are a tad bit fragile) . Slices feature a very busy matrix containing eucritic clasts and a rather thick black fusion crust. Each slice will come in a quality labeled meteorite display box. A VERY PRETTY EUCRITE, with only a few slices available.

Petrography as follows:

Very fresh specimen consisting of diabase clasts within a matrix of related debris. Minerals are exsolved pigeonite, orthopyroxene, clinopyroxene, calcic plagioclase, silica polymorph, ilmenite, troilite and minor Ti-chromite. Orthopyroxene (Fs59.1-59.5Wo1.6-1.7, FeO/MnO = 31-32, N = 3), clinopyroxene exsolution lamella (Fs25.2Wo42.6, FeO/MnO = 31), discrete clinopyroxene (Fs24.0Wo44.9, FeO/MnO = 26), plagioclase (An84.8-86.3Or0.9-0.8, N = 2).
