SAMPLE INFO : 91CND15

Sample ID:	91CND15
Station ID:	91CND15
Latitude:	58.914702
Longitude:	-153.533737
Datum:	NAD83
Date Sampled:	1991-01-01
Sample Type 1:	Lava

Text Description:
Very fresh, highly fractured andesite outcrop at 2300 ft elevation between Spotted and striped glaciers. Appears to be very young. Porphyritic olivine andesite containing ~25% phenocrysts of olivine (20%, up to 1.2 x 0.6 mm), pyroxene (3%, 0.6 x 0.3 mm), and plagioclase (2%, 0.6 x 0.2 mm) in a matrix dominated by interlocking plagioclase microlites (200 x 15 microns) and pyroxene (20 microns). Olivine phenocrysts contain euhedral translucent brown chromite octahedral.
