The overall texture consists of coarse-grained inclusions set in a
fine-grained matrix. The matrix contains isolated mineral clasts, mainly
consisting of augite, plagioclase and olivine, and a fine grained mineral
debris enclosed within a dark, partly glassy and vesicular matrix. The
large coarse grained inclusions consist of
elongated plagioclase and clinopyroxene crystals set in a glassy matrix.
Opaque phases are represented by ilmenite, ulvospinel
