SAMPLE INFO : 94SJP15

Sample ID:	94SJP15
Station ID:	94SJP15
Latitude:	62.29128056
Longitude:	-143.2654606
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Lava
Field Lithology:	Basaltic Andesite

Text Description:
Flow-like' to brecciated outcrop within brecciated material at the top of Site 12. Fine grained, vesicular, holocrystalline, seriate to glomeroporphyritic with a matrix of mesostasis, opaque, plagioclase, orthopyroxene, clinopyroxene and minor altered patches. Plagioclase phenocrysts (An28-An63) are up to 2.2 mm and frequently have sieve textured cores, normal zoning, overgrowth rims; some grains have oscillatory zoning. Orthopyroxene phenocrysts are up to 0.8 mm and some have clinopyroxene rims. Olivine phenocrysts are up to 0.6 mm and are slightly altered; a few have opaque inclusions. Clinopyroxene phenocrysts are up to 0.55 mm.
