Writeup from MN J18:
Y980497 Olivine-phyric shergottite
The PTS shows a porphyritic texture composed of olivine phenocrysts (up to 2 mm) set in a fine-grained matrix. The fine-grained matrix consists of orthopyroxene laths (~ 10-20 x 30-50 μm) with dark glassy materials filling the interstices. The composition of olivine is Fa18-27 and that of low-Ca pyroxene is Fs18-25 with FeO/MnO = 19-42 (av. ~30). This meteorite is probably paired with Y980459.
