SAMPLE INFO : Barth_1956_13

Sample ID:	Barth_1956_13
Station ID:	Barth_1956_13
Latitude:	56.58
Longitude:	-169.63
Datum:	NAD83
Date Sampled:	1948-01-01
Sample Type 1:	Lava
Field Lithology:	Basalt

Text Description:
Sample of a glassy olivine basalt, Pribilof type, that is a vesicular gray flow or sill of a glassy basaltoid rock. The only crystalline silicates are olivine in small grains measuring about 0.05 mm across, and plagioclase in laths about 0.07 x 0.01 mm. They line in a glassy, inhomogeneous matrix containing ore and apatite in distinct crystals, and various unidentified products of incipient crystallization. The Pribilof type basaltoid lava flows have olivine, plagioclase, and glass as the only essential phases.
