SAMPLE INFO : 91CND17
Sample ID:91CND17
Station ID:91CND17
Latitude:58.85241
Longitude:-153.5438
Datum:NAD83
Date Sampled:1991-01-01
Sample Type 1:Lava
Text Description:
60 cm diameter radially fractured block lying on surface at crater rim. Porphyritic andesite. ~40% phenocrysts of plagioclase (up to 1.0 x 0.5 mm), pyroxene (0.5 x 0.4 mm), and opaque Fe-Ti oxides in a matrix of devitrified glass and subordinate microphenocrysts and microlites. Pl:px ~ 3:2. About half of the plagioclase phenocrysts are extensively sieved, the rest are nearly free of disequilibrium textures.
