Sample ID:94SJP44A
Station ID:94SJP44A
Latitude:62.475
Longitude:-143.1596
Datum:NAD83
Date Sampled:1994-00-00
Sample Type 1:Lava
Field Lithology:Andesite
Text Description:
Platy to rubbly outcrop on the top of Site 5. Fine grained, hypocrystalline, intersertal, seriate to glomeroporphyritic with a matrix of brown glass, mesostasis, opaque, plagioclase and clinopyroxene. Plagioclase phenocrysts (An40 - An63) are up to 3.1 mm and commonly have sieve textured zones, oscillatory zoning, resorbed rims or resorption embayments. Olivine phenocrysts are up to 1.0 mm. Orthopyroxene phenocrysts are up to 1.0 mm and some have clinopyroxene rims and/or opaque inclusions. Clinopyroxene phenocrysts are up to 0.8 mm. Opaque phenocrysts are up to 0.2 mm. 70.4% matrix, 22.6% plagioclase, 0.6% olivine, 2.1% clinopyroxene, 3.2% orthopyroxene, 0.1% opaque, 1.0% vesicles.
