Distribution of Quaternary rhyolite domes of the Coso Range, California: implications for extent of the geothermal anomaly. Distribution of Quaternary rhyolite domes of the Coso Range, California: implications for extent of the geothermal anomaly.
38 separate domes and flows of phenocryst-poor, high-silica rhyolite of similar major element chemical composition were erupted over the past 1My from vents arranged in a crudely S-shaped array atop a granitic horst in the Coso Range, California. Most of the extrusions are probably less than about 0.3My old. The central part of the rhyolite field is characterized by high heat flow, low...

Potential hazards from future eruptions in the vicinity of Mount Shasta Volcano, Northern California Potential hazards from future eruptions in the vicinity of Mount Shasta Volcano, Northern California
Mount Shasta has erupted, on the average, at least once per 800 years during the last 10,000 years, and about once per 600 years during the last 4,500 years. The last known eruption occurred about 200 radiocarbon years ago. Eruptions during the last 10,000 years produced lava flows and domes on and around the flanks of Mount Shasta, and pyroclastic flows from summit and flank vents...

Geodolite measurements of deformation near Hollister, California, 1971-1978 Geodolite measurements of deformation near Hollister, California, 1971-1978
A 24‐station trilateration network spanning the San Andreas and Calaveras faults near Hollister, California, has been surveyed each year between 1971 and 1978, inclusive. Two moderate (ML = 5) earthquakes have occurred within the network during the interval. No convincing preseismic or coseismic anomalies associated with those earthquakes have been identified. The deformation of the...

Deformation across the Salton Trough, California, 1973-1977 Deformation across the Salton Trough, California, 1973-1977
A trilateration network extending across the San Andreas, San Jacinto, and Elsinore faults in the vicinity of the Salton Sea, California, has been surveyed to very high precision several times in the 5‐year interval 1973–1977. The average strain across the entire network is essentially a uniaxial north‐south contraction at the rate of about 0.3 μstrain/a. There is no substantial strain

Comparison of Miocene provincial foraminiferal stages to coccolith zones in the California Continental Borderland Comparison of Miocene provincial foraminiferal stages to coccolith zones in the California Continental Borderland
Biostratigraphic ages determined by planktic coccoliths and benthic foraminifera for the same core samples from the California Continental Borderland suggest that a significant overlap exists among provincial Miocene stages of California and that some of the benthic foraminifera commonly used to recognize these stages are time-transgressive. For example, samples assigned to the middle...
