SAMPLE INFO : 81AYb 167

Sample ID:	81AYb 167
Station ID:	81AYb 167
Latitude:	57.224
Longitude:	-156.66539821083
Datum:	NAD83
Date Sampled:	1981-01-01
Sample Type 1:	Lava
Field Lithology:	Andesite

Text Description:
Fine-grained to very fine-grained, dark-gray (N 3), porphyritic andesite (S; high-silica andesite G) containing common very light-gray (N 8) phenocrysts of plagioclase. Major minerals are plagioclase (An 65), clinopyroxene, and sparse orthopyroxene. Pilotaxic groundmass contains weakly flow foliated plagioclase laths and glass. Rare altered phenocrysts have been olivine, otherwise rock is fresh appearing
