SAMPLE INFO : 91CND21

Sample ID:	91CND21
Station ID:	91CND21
Latitude:	58.942778
Longitude:	-153.559627
Datum:	NAD83
Date Sampled:	1991-01-01
Sample Type 1:	Lava

Text Description:
Sample from base of flow between Spotted and striped glaciers. Porphyritic andesite. ~50% phenocrysts of plagioclase (typically 1.0 x 0.3 mm), and pyroxene (typically 1.1 x 0.4 mm), in a groundmass composed of about 50% brown glass and microphenocrysts on microlites of plagioclase, pyroxene, and opaque oxides. Pl:px ~ 3:2. A minority of the plagioclase phenocrysts have sieved zones, the rest are nearly free of disequilibrium textures.
