Text Description:
Dike-scoria contact where feeder dike (94SJP105A) cuts through vent scoria of a small cinder cone. Fine grained, vesicular, holocrystalline, porphyritic, oxidized with a matrix of mesostasis, plagioclase, and opaque. Plagioclase phenocrysts (An55) are up to 0.25 mm, mostly as small laths; occasional larger grains have sieve textured zones. An altered phase in up to 0.38 mm.
