NWA 6577 Polymict Eucrite Meteorite 2.74g Crusted Part Slice

 

Item for auction is 2.74g crusted slice of NWA 6577 Polymict Eucrite. Tony Irving reports it to be a Polymict breccia composed of lithic and mineral fragments derived mostly from basaltic and cumulate eucrite lithologies, plus sparse (<10 volume%) diogenitic orthopyroxene. Exsolved pigeonite consists of exsolution lamellae of clinopyroxene (Fs26.7-26.8Wo43.4; FeO/MnO = 28.2-31.1) within host orthopyroxene (Fs59.3-61.3.7-2.1; FeO/MnO = 29.8-30.2). Other minerals are homogeneous pigeonite (Fs59.8Wo19.0; FeO/MnO = 31.6), orthopyroxene (Fs21.5Wo2.4; FeO/MnO = 29.1), calcic plagioclase, silica polymorph, ilmenite and troilite. This stone looked like it had everything but the kitchen sink thrown in - I would have guessed it to have been a howardite. But I am not complaining because as you can see, it is quite an impressive meteorite.
