SAMPLE INFO : 93SJP64

Sample ID:	93SJP64
Station ID:	93SJP64
Latitude:	62.3996
Longitude:	-143.1371
Datum:	NAD83
Date Sampled:	1993-00-00
Sample Type 1:	Lava
Sample Type 2:	Flow
Field Lithology:	Andesite

Text Description:
Approximately 25’ thick flow at Site 4. Fine-grained, holocrystalline, seriate porphyritic with a matrix of mesostasis, opaque and green alteration. Plagioclase phenocrysts (An40 - An57) are up to 1.55 mm and some have sieve textured intermediate zones or cores and complex zoning. Orthopyroxene phenocrysts are up to 0.6 mm and some have clinopyroxene rims. Clinopyroxene phenocrysts are sparse and ~0.2 mm in length.
