Geologic map and map database of the Spreckels 7.5-minute Quadrangle, Monterey County, California
Introduction
The Spreckels quadrangle lies at the north end of the Sierra de Salinas and extends from the Salinas Valley on the northeast across Los Laurelles Ridge south to Carmel Valley, an intermontane valley that separates the Santa Lucia Range from the Sierra de Salinas (fig. 1). The Toro Regional Park occupies the east-central part of the quadrangle, whereas the former Fort Ord Military R
Geologic maps and structure sections of the southwestern Santa Clara Valley and southern Santa Cruz Mountains, Santa Clara and Santa Cruz Counties, California
This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (scvmf.ps, scvmf.pdf, scvmf.txt), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineat

Introduction
These geologic maps and accompanying structure sections depict the geology and structure of much of northwestern California and the adjacent continental margin. The map area includes the Mendocino triple junction, which is the juncture of the North American continental plate with two plates of the Pacific ocean basin. The map area also encompasses major geographic and geologic prov
Geologic map of the Lone Pine 15' quadrangle, Inyo County, California
Oblique aerial view west across Owens Valley in Lone Pine 15' quadrangle. In distance, Sierra Nevada, capped by Mount Whitney (elev. 14,494 ft; 4,418 m). In middle distance, Alabama Hills, town of Lone Pine, and Owens River. In foreground, Kern Knob, at base of Inyo Mountains. Movement along Owens Valley Fault Zone, at base of Alabama Hills, caused great Lone Pine earthquake of 1872 (estimated Ric
Lithologic, age group, magnetopolarity, and geochemical maps of the Springerville Volcanic Field, east-central Arizona
The Springerville volcanic field is one of the many late Pliocene to Holocene, mostly basaltic, volcanic fields present near the Colorado Plateau margin (fig. 1, in pamphlet). The field overlies the lithospheric transition zone between the Colorado Plateau and the Basin and Range Province (Condit and others, 1989b). Establishing relations in time, space, and composition of the rocks of these plate
