Writeup from MB 103:

Grove Mountains 13001 (GRV 13001)        72°59’08"S, 75°14’18"E

Antarctica

Found: 6 Feb 2014

Classification: HED achondrite (Eucrite)

History: One of 583 meteorites collected by CHINARE during the 2013/2014 field season.

Physical characteristics: (H. Chen, B. Miao, Z. Xia, L. Xie, GUT): This achondrite is 75% covered with a shiny black fusion crust, with a total mass of 1299.1 g. The interior is a smoky gray color, showing a partially brecciated texture. Many cracks penetrate the interior of this meteorite. Dimensions: 8.5 × 9.6 × 9.0 cm.

Petrography: (H. Chen, B. Miao, Z. Xia, L. Xie, GUT): Breccia containing a variety of basaltic lithologies, generally plagioclase-rich, with lath-like plagioclase typically 0.1-0.5 mm long, and some pyroxene laths up to 1.0 mm. A silica phase is commonly present. A macroscopically dark gray, fine-grained clast (mean grain size 20-50 μm) with equilibrated metamorphic texture also contains a silica phase. Accessories are ilmenite, troilite and rare iron metal.

Geochemistry: (H. Chen, B. Miao, Z. Xia, L. Xie, GUT): Orthopyroxene compositions are Fs58.6-59.7Wo1.61-4.70, median Fs59.3Wo2.9, n=15. Clinopyroxene compositions are Fs27.0-58.3Wo7.74-60.6, median Fs42.1Wo34.5, n=16. Plagioclase: An92.7-96.1Or0.35-0.96, median An94.9Or0.64, n=8. Bulk analysis of fusion crust by EPMA (wt%): FeO=22.4%, MnO=0.68%, Fe/Mn=32.9.  Isotopic data (M.E. Sanborn and Q.-Z. Yin, UCD): oxygen,  Δ17O=-0.25±0.02; chromium, εCr=-0.33±0.09.

Classification: Based on texture, mineral composition and bulk Fe/Mn this is a eucrite (basaltic polymict eucrite).
