Structural implications of an offset Early Cretaceous shoreline in northern California Structural implications of an offset Early Cretaceous shoreline in northern California
Recognition of a nonmarine to marine transition in sedimentary rocks at Glade Creek and Big Bar in the southern Klamath Mountains permits reconstruction of the approximate position of a north-trending Early Cretaceous (Valanginian) shoreline. At the southern end of the Klamath Mountains, the shoreline is displaced 60 mi or more to the east by a west-northwest-trending fault zone. South...

Geologic map of Late Cenozoic deposits, Santa Clara County, California Geologic map of Late Cenozoic deposits, Santa Clara County, California
This map is the first of several in the San Francisco Bay region showing the distribution and differentiation of the late Cenozoic alluvial, estuarine, and volcanic deposits. The sedimentary deposits of gravel, sand, silt, and clay were separated into geologic map units on the basis of their post-depositional soil development, texture, and geomorphology. Some of the geologic units are...

Geologic interpretation of reconnaissance aeromagnetic survey of northeastern Alaska Geologic interpretation of reconnaissance aeromagnetic survey of northeastern Alaska
Aeromagnetic reconnaissance of northeastern Alaska in 1965 covered approximately 100,000 square miles, from lat 64° N. to the Arctic Ocean and from the Alaska-Yukon boundary to long 148°30' W. A magnetic contour map was compiled from data from the 1965 survey and earlier surveys. On the basis of these data, northeastern Alaska may be divided into five areas, each having a distinct...
