SAMPLE INFO : 94SJP41
Sample ID:94SJP41
Station ID:94SJP41
Latitude:62.43407106
Longitude:-143.1901901
Datum:NAD83
Date Sampled:1994-00-00
Sample Type 1:Lava
Sample Type 2:Dike
Field Lithology:Basaltic Andesite
Text Description:
Coarse-grained plagioclase-phyric material that may be a dike at Site 6. Fine-grained, hypocrystalline, porphyritic to glomeroporphyritic with a matrix of mesostasis, opaque, and plagioclase. Plagioclase phenocrysts (An57-An58) are up to 5.6 mm and are frequently sieve textured throughout with occasional thin overgrowth rims. Clinopyroxene phenocrysts are up to 0.6 mm and often in glomeroporphyritic clusters with plagioclase. Olivine phenocrysts are 2.0-0.2 mm and frequently have rounded edges, and a few have opaque or plagioclase inclusions. Mode: 82.7% matrix, 14.4% plagioclase, 2.2% olivine, 0.7% clinopyroxene.
