SAMPLE INFO : 94SJP5

Sample ID:	94SJP5
Station ID:	94SJP5
Latitude:	62.30267091
Longitude:	-143.2543497
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Lava
Sample Type 2:	Flow
Field Lithology:	Basaltic Andesite

Text Description:
Approximately 50' thick dipping flow overlying 94SJP3 (sBA2) at Site 12. There is a rubbly zone in between 94SJP3 and 94SJP5. Fine grained, holocrystalline, intergranular, seriate porphyritic with a matrix of mesostasis, opaque, clinopyroxene, plagioclase, and orthopyroxene?. Plagioclase phenocrysts (An41-An46) are up to 1 mm, display normal zoning and may include pyroxene or opaque grains. Orthopyroxene phenocrysts are up to 0.25 mm, can have altered cores and frequently include opaque grains. Clinopyroxene phenocrysts are uncommon and up to 0.1 mm.
