SAMPLE INFO : 94SJP111

Sample ID:	94SJP111
Station ID:	94SJP111
Latitude:	62.23682799
Longitude:	-143.3404597
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Lava
Sample Type 2:	Flow
Field Lithology:	Andesite

Text Description:
Flows 15-20’ thick with well developed vesicular/rubbly flow tops. Outcrop weathers into large blocks and plates. Overlies black scree that may be vitrophyre shown by Lowe et al., 1983. Fine grained, vesicular, hypocrystalline, porphyritic with a matrix of brown glass, opaque, plagioclase, clinopyroxene and orthopyroxene. Plagioclase phenocrysts (An57 - An63) are up to 5.17 mm and occasionally have sieve textured zones, pyroxene inclusions, resorption embayments and/or oscillatory zoning. Orthopyroxene phenocrysts are up to 3.0 mm. Clinopyroxene phenocrysts are up to 3.5 mm.
