SAMPLE INFO : Riehle_1987_16

Sample ID:	Riehle_1987_16
Station ID:	Riehle_1987_16
Latitude:	57.0179
Longitude:	-157.1864
Datum:	NAD83
Sample Type 1:	pyroclastic density current

Text Description:
Sample of basal Yantarni cone deposits on the north flank. These are pyroclastic rocks composed of monolithic, slightly vesicular cobble- to boulder-sized clasts with a small amount of fine-grained matrix. Texture: Porphyry; groundmass <0.1 mm, plagioclase microlites and rare glass; seriate phenocrysts. Alteration: None
