SAMPLE INFO : 94SJP11B

Sample ID:	94SJP11B
Station ID:	94SJP11B
Latitude:	62.28850246
Longitude:	-143.267
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Lava
Sample Type 2:	Block
Field Lithology:	Basaltic Andesite

Text Description:
Block from brecciated material at Site 12. This unit is cut by a dike (94SJP11A). Fine grained, vesicular, hypocrystalline, intersertal, seriate to glomeroporphyritic with a matrix of brown glass, opaque, plagioclase, orthopyroxene, clinopyroxene and minor calcite. Plagioclase phenocrysts (An30-An64) are up to 7.5 mm and frequently have sieve textured cores, normal zoning, and overgrowth rims; oscillatory zoning is less common. Olivine phenocrysts are up to 0.5 mm and some have a rim of small orthopyroxene crystals. Orthopyroxene is up to 0.6 mm and some have clinopyroxene rims.
