Paleozoic and Precambrian rocks of Alaska and their role in its structural evolution
Michael Churkin Jr.
1970, Open-File Report 70-64
Acknowledging that there are large gaps in the knowledge of the geology of Alaska, the following threefold subdivision of Alaska into Paleozoic tectonic elements is proposed: Southern Alaska--the Alaska Range and farther south--is the northern end of the Paleozoic Cordilleran geosyncline that rims the eastern Pacific. Northern Alaska--the northeastern Brooks...

Edwin H. McKee, Miles L. Silberman
1970, Bulletin of the Geological Society of America (81) 2317-2327
Potassium-argon dating of Tertiary igneous rocks in Lander County, central Nevada, indicates that igneous activity was episodic and can be separated into three periods. Igneous activity started abruptly about 37 m.y. ago with local extrusion of andesitic to quartz-latitic lava flows and intrusion of hypabyssal rocks of similar composition. This...
Deuterium content of snow cores from Sierra Nevada area
I. Friedman, G.I. Smith
1970, Science (169) 467-470
The relative deuterium content was measured on 37 snow cores collected in April 1969 in the Sierra Nevada. The deuterium content varies inversely with altitude of collection (approximately 40 per mil per 1000 meters) but is unrelated to latitude. The altitude relationship is particularly well defined west of the crest...
