SAMPLE INFO : 47AC98
Sample ID:47AC98
Station ID:47AC98
Latitude:51.9288
Longitude:179.5977
Datum:NAD83
Date Sampled:1947-01-01
Sample Type 1:Lava
Sample Type 2:Flow
Final Unit:Pochnoi volcanics
Text Description:
Specimen 47AC98 is a medium-brownish-gray (5R 5/1) dense lava, with planar vesicles, from a flow 4 feet thick on the flank of the denuded cone just south of Fenner Creek and north of Sugarloaf (141,45O'E., 280,500' N.). The texture is seriate, and intersertal. The constituents are plagioclase (0.01 to 1 mm in diameter) averaging about An77, augite (0.01 to 0.2 mm in diameter), olivine (Fa30, determined from 2V), and magnetite, with intersertal glass.
