SAMPLE INFO : 94SJP101B

Sample ID:	94SJP101B
Station ID:	94SJP101B
Latitude:	62.35628735
Longitude:	-143.198241
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Lava
Sample Type 2:	Dike
Field Lithology:	Andesite

Text Description:
Approximately 5’ thick dike? that trends N40°E at Site 13. It looks the same as 94SJP101C. Fine grained, holocrystalline, porphyritic with a matrix of mesostasis, opaque, plagioclase, clinopyroxene and alteration. Plagioclase phenocrysts (An41 - An62) are up to 5.12 mm and a few have oscillatory zoning. Orthopyroxene phenocrysts are up to 1.2 mm and some have clinopyroxene rims. Clinopyroxene phenocrysts are up to 1.75 mm. An altered phase, olivine?, up to 1.12 mm, is sometimes rimmed by small pyroxene grains.
