Regional stratigraphic studies have pointed...

Sand was the dominant type of land-derived sediment deposited in the Sunnyside district during the regressive phases. Sand bodies prograded seaward in response to changing sediment...
Direct-current arc and alternating-current spark emission spectrographic field methods for the semiquantitative analysis of geologic materials
D. J. Grimes, A. P. Marranzino
1968, Circular 591
Two spectrographic methods are used in mobile field laboratories of the U. S. Geological Survey. In the direct-current arc method, the ground sample is mixed with graphite powder, packed into an electrode crater, and burned to completion. Thirty elements are determined. In the spark method, the sample, ground to pass...
