SAMPLE INFO : 88VS12
Sample ID:88VS12
Station ID:88VS12
Latitude:53.100150953755
Longitude:-168.73254480683
Datum:NAD83
Date Sampled:1988-01-01
Sample Type 1:Lava
Text Description:
Sample from southwest flank 1,450’ asl. Porphyritic olivine basaltic andesite. Phenocrysts of plagioclase (20%, up to 0.8x 0.3 mm) and olivine (5%, 0.6–0.2 mm) in a groundmass of plagioclase laths (70 x 10 microns), smaller intersertal pyroxenes and opaque grains, and interstitial glass. This sample is one of very few collected from Vsevidof in 1988 that has plagioclase crystals with extensive spongy regions. They are typically throughout the crystals, with the exception of a thin (~ 20 micron) clear rim.
