Devonian rocks of the Yukon-Porcupine Rivers area and their tectonic relation to other Devonian sequences in Alaska
Devonian rocks along the Yukon River near the Alaska-Yukon boundary comprise 250 feet of limestone and shale and 800 feet of chert and siliceous shale, all referred to the McCann Hill Chert of Early to Late Devonian age; about 3,000 feet of non-marine chert-pebble conglomerate, graywacke, and shale of the Nation River Formation (Late Devonian); and about 3,000 feet of an unnamed chert and siliceou

Standards for water quality
The quality which is necessary depends on the use to which the water will be put. Because uses vary, so also must quality standards. Maintaining any level of quality presents a problem of cost and depends on variations in natural water characteristics, in time and space, and variations in volume and types of wastes. For quality standards appropriate to a given water body, hydrologic network data c

Devonian of the Northern Rocky Mountains and plains
The Devonian System, represented predominantly by shallow-water marine carbonate, is widespread in Montana, Wyoming, eastern Idaho, North Dakota, South Dakota, and northwestern Nebraska. It comprises cratonic rocks in the east and miogeosynclinal rocks in the west.
The cratonic rocks thicken generally northward from their southern limit in Wyoming across a broad shelf that occupies most of Wyoming

Devonian of the Southwestern United States
The structural framework that controlled Devonian deposition consisted of, from west to east: (1) a eugeosynclinal area in northern California and western Nevada; (2) a miogeosynclinal area in southeastern California, eastern Nevada, and western Utah; and (3) a cratonic area in Arizona, eastern Utah, Colorado, New Mexico, and western Texas, east of a northeast-trending hinge line (Wasatch line).

Devonian of the Appalachian Basin, United States
Although Devonian rocks in the Appalachians have been studied for more than 150 years, they are poorly known in most of the area. The nearly complete Devonian sequence in New York has been established as the North American standard of reference.
The structural belt that includes unmetamorphosed Devonian geosynclinal strata is bonded on the southeast and east by metamorphic and igneous rocks of the

Succession of rugose coral faunas in the Lower and Middle Devonian of eastern North America
Rocks of Early Devonian age are widely but sporadically distributed in the eastern half of North America and coral studies are based on a very incomplete record. Middle Devonian rocks are thicker and cover a greater area.
Both Early and Middle Devonian corals are more similar to western European species than they are to presumably contemporary forms from western North America, although some of the
