SAMPLE INFO : 54-D-84
Sample ID:54-D-84
Station ID:54-D-84
Latitude:53.924
Longitude:-166.994
Datum:NAD83
Date Sampled:1954-01-01
Sample Type 1:Lava
Sample Type 2:Flow
Field Lithology:Andesite
Text Description:
Andesite vitrophyre from a flow of Eider Point basalt 4 miles northwest of Makushin Volcano. It is grayish black and contains plagioclase phenocrysts as large as 1 millimeter in sheeted and finely vesicular glass. Phenocrysts compose 1 percent of the rock and include euhedral to fragmental labradorite and traces of clinopyroxene and magnetite. The glassy groundmass has alined microlites, dusty inclusions, and strong flow bands of light and dark streaks, and contains some euhedral cristobalite on vesicule walls.
