Clasts and matrix are dominantly composed of exsolved pyroxene and plagioclase grains of variable grain size ranging from 0.1 to 1 mm. Accessories include chromite, pyrrhotite, and silica.

Geochemistry: Low-Ca pyroxene: Fs59±1.2Wo3.3±1.1 (Fs57.3-61.1Wo1.9-5.1, n=15, FeO/MnO=28-34); Ca-pyroxene: Fs27.1±0.9Wo42.6±0.9 (Fs25.8-28.9Wo41-44.3, n=14, FeO/MnO=29-34); calcic plagioclase: An88.9±0.5 (An88.1-90, n=14)
