SAMPLE INFO : 93SJP4

Sample ID:	93SJP4
Station ID:	93SJP4
Latitude:	62.36351051
Longitude:	-143.0646
Datum:	NAD83
Date Sampled:	1993-00-00
Sample Type 1:	Lava
Sample Type 2:	Dike
Field Lithology:	Basaltic Andesite

Text Description:
Dike trending S35E at Site 9. Fine-grained, vesicular, diktytaxitic, holocrystalline, intergranular, seriate porphyritic with a matrix of mesostasis, opaque, clinopyroxene and plagioclase. Plagioclase phenocrysts (An34-An59) are up to 2.25 and the larger phenocrysts have sieved textured zones, tooth-like overgrowth rims or resorbed rims, oscillatory zoning, and pyroxene inclusion, while smaller grains display normal zoning. Olivine phenocrysts are up to 1.2 mm and some are slightly altered, resorbed edges are common, and a few have opaque inclusions. Clinopyroxene phenocrysts are up to 0.95 mm and a few have orthopyroxene cores. Orthopyroxene is up to 0.3 mm and altered. Mode: 63.0% matrix, 24.4% plagioclase, 2.0% olivine, 1.8% clinopyroxene, 0.3% orthopyroxene, 0.4% alteration, 8.1% vesicles.
