SAMPLE INFO : 93SJP61

Sample ID:	93SJP61
Station ID:	93SJP61
Latitude:	62.41907002
Longitude:	-143.1693562
Datum:	NAD83
Date Sampled:	1993-00-00
Sample Type 1:	Lava
Sample Type 2:	Flow
Field Lithology:	Andesite

Text Description:
An approximately 20’ thick flow at Site 4. Fine-grained, holocrystalline, intergranular, seriate porphyritic with a matrix of mesostasis, opaque, plagioclase and alteration. Plagioclase phenocrysts (An38 - An62) are up to 1.1 mm and some have sieve textured cores or intermediate zones; complex zoning is present. Orthopyroxene phenocrysts are up to 0.85 mm and some have clinopyroxene rims or opaque inclusions. Clinopyroxene phenocrysts are up to 0.15 mm.
