SAMPLE INFO : 81AYb 168

Sample ID:	81AYb 168
Station ID:	81AYb 168
Latitude:	57.18760401
Longitude:	-156.7037293
Datum:	NAD83
Date Sampled:	1981-01-01
Sample Type 1:	Lava
Field Lithology:	Andesite

Text Description:
Ugashik A-3. southeast side of Mount Kialagvik. Medium- to fine-grained, medium-gray (N5), hyalopilitic andesite (S; high-silica andesite G) porphyry containing very light gray (N 8) plagioclase phenocrysts and sparse dark-greenish-gray (5 G/Y 4/1) pyroxene phenocrysts. Major minerals are plagioclase (An 64), clinopyroxene, and lesser opaque oxides. Abundant phenocrysts in groundmass of glass and very fine grained plagioclase. Most phenocrysts and crystals have resorbed edges.
