SAMPLE INFO : 94SJP61

Sample ID:	94SJP61
Station ID:	94SJP61
Latitude:	62.27294685
Longitude:	-143.18796
Datum:	NAD83
Date Sampled:	1994-00-00
Sample Type 1:	Tephra Fall
Sample Type 2:	Bomb
Field Lithology:	Basaltic Andesite

Text Description:
Bomb from the remnants of a cinder cone at Gutbuster. Overlies 94SJP62.Fine grained, vesicular, holocrystalline, trachytic, porphyritic with a matrix of mesostasis, opaque, and plagioclase. Plagioclase phenocrysts (An43-An55) are up to 1.0 mm and occasionally have oscillatory zoning. Olivine phenocrysts are up to 2.12 mm and occasionally have skeletal habit. Clinopyroxene phenocrysts are up to 0.35 mm and are strained with undulatory extinction and bent cleavage planes.
