SAMPLE INFO : 94SJP93

Sample ID:	94SJP93
Station ID:	94SJP93
Latitude:	62.3635005
Longitude:	-143.4468592
Datum:	NAD83
Date Sampled:	1994-00-00

Text Description:
Grab sample from rubble crop with boulders up to 6' diameter on the west side of Goat Creek. Scoriaceous material on surface of the outcrop. Fine grained, vesicular, holocrystalline, intergranular, seriate porphyritic with a matrix of mesostasis, opaque, plagioclase, clinopyroxene and orthopyroxene. Plagioclase phenocrysts (An41-An47) are up to 6.5 mm and occasionally have sieve textured zones or oscillatory zoning. Olivine phenocrysts are up to 0.4 mm and are often rimmed with small orthopyroxene crystals; occasionally have opaque inclusions. Orthopyroxene phenocrysts are up to 1.65 mm.
