SAMPLE INFO : 94SJP58D

Sample ID:	94SJP58D
Station ID:	94SJP58
Latitude:	62.29
Longitude:	-143.2387938
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Lava

Text Description:
Vesicular block from base of brecciated unit at Site 12. Fine grained, vesicular, hypocrystalline, intersertal, seriate to glomeroporphyritic with a matrix of brown glass, opaque, microlites and plagioclase. Plagioclase phenocrysts (An26-An61) are up to 3.4 mm, some grains have sieve textured cores, resorption embayments, display both normal or oscillatory zoning, and may have overgrowths. Olivine phenocrysts are up to 2 mm. Orthopyroxene phenocrysts are up to 0.5 mm.
