SAMPLE INFO : 47AC113
Sample ID:47AC113
Station ID:47AC113
Latitude:51.9288
Longitude:179.5977
Datum:NAD83
Date Sampled:1947-01-01
Sample Type 1:Tuff
Field Lithology:Dacite
Final Unit:CFE ignimbrite - bulk
Text Description:
A composite representing the full thickness of the tuff, as exposed in a gully at 122,600' E., 284,250' N. No section was cut as it was not certain that one section could properly represent the composite. It is probable that the composite sample is contaminated dacite.
