SAMPLE INFO : 91CND07

Sample ID:	91CND07
Station ID:	91CND07
Latitude:	58.898331
Longitude:	-153.459718
Datum:	NAD83
Date Sampled:	1991-01-01
Sample Type 1:	Lava

Text Description:
Very dark gray lava in older volcanics. Geodes and ruby red plagioclase indicate alteration and silica mobilization. Not much fresh rock in immediate area. Porphyritic two-pyroxene dacite. ~25% phenocrysts of plagioclase (up to 1.0 x 0.4 mm), pyroxene (0.8 x 0.3 mm), and opaque Fe-Ti oxides in a matrix of devitrified glass and subordinate microphenocrysts and microlites. Pl:px ~ 3:2
