Measurements were made on thin section billets or on clasts themselves when they were of suitable size for the instrument. The variability of the magnetic susceptibility is related both to variations in the primary magnetic mineral content of the source rocks as well as to secondary magnetic ...

Is unusual animal behavior observed before earthquakes? Yes and no

by K. Verosub and Benjamin Hart

Geophysical Research Letters, 1979

This schedule was developed to maximize the reliability and validity of the reports through the application of accepted social science methodology. Interviews with 50 households near Willits, California, produced 17 reports of unusual animal behavior prior to that earthquake.

Maturation anomalies in sediments underlying thick volcanic strata, Oregon: Evidence for a thermal event

Geology, 1987

Vitrinite reflectance profiles from three drill holes in Oregon where sediments are mantled by th... more Vitrinite reflectance profiles from three drill holes in Oregon where sediments are mantled by thick sequences of volcanic rocks suggest that the sediments were subjected to an unusual diagenetic history. Anomalous, near-constant maturation profiles in sedimentary sequences more than 1300 m thick indicate that the levels of thermal maturity of organic matter in the sediments below the volcanic cover of the Pacific northwest were sufficiently high to have generated hydrocarbons. A hydrothermal mechanism appears to be the most effective form of thermal input, and supporting evidence can be found in the authigenic mineralization of the sediments. The occurrence of vertical maturation profiles in east-central Oregon may be associated with moderate-temperature geothermal systems resulting from a late Oligocene to early Miocene thermal event related to the incipient stages of basaltic volcanism of the Columbia River Group. The uniform maturation of the entire sedimentary column under the volcanic cover has broad implications for the exploration for oil and gas in the Pacific northwest because the presence of mature source rocks in these volcanically lidded basins provides some insight into the petroleum potential of the large volcanic-covered areas in Oregon, Washington, and California.

Late Cenozoic stratigraphy of the Feather and Yuba rivers area, California, with a section on soil development in mixed alluvium at Honcut Creek

Each discipline provides information important to the others. From geomorphic relations we can determine the relative ages of deposits and soils; from stratigraphy we can place age constraints on the soils. Field investigations and mineralogic and sedimentologic studies provide information on the nature and types of deposits in which soils form. As a result of our work, we have estimated rates of soil formation, inferred processes of soil formation from trends in soil development with increasing age, and obtained information on the types of weathering that occur in various areas. In return, soil development and soil genesis have provided data on the age of landforms; the timing and duration of sedimentation, and, in some cases, the history of climatic fluctuations. Between 1978 and 1983, a coordinated and systematic study was conducted on soil development in different types of geologic deposits in the Western United States. The goals of this project, led by the late D.E. Marchand and subsequently by M.N. Machette, were to learn whether rates of chemical, physical, and mineralogic transformations could be determined from soil chronosequences; hqw these rates vary in different mineralogic and climatic environments; and how accurately soils can be used for such problems as estimating the ages of deposits, periods of landscape stability, and timing of fault movements. This series of reports presents data from several soil chronosequences of that project. More than 100 analyses on more than 1,000 samples were performed on soils collected in the Western United States. Some results have appeared in various books, journals, and maps (for example,

Relative geomagnetic paleointensity across the Jaramillo Subchron and the Matuyama/Brunhes Boundary

These data indicate that during the Jaramillo subchron, there was a gradual decrease in palcointensity from the onset of the subchron to its termination. The data from the subchron also display high-amplitude, fine-scale features that may be coherent over the scale of an ocean basin. Furthermore, there was a rapid rise in paleointensity immediately after the termination of the Matuyama/Brunhes polarity transition. These observations support the hypothesis that an asymmetrical saw-tooth pattern in palcointensity may be a common characteristic of polarity transitions; however, a better understanding of the high-amplitude features is needed before definitive conclusions can be drawn about the overall behavior of the field. The coherence of fine-scale features across such large distances does not support the suggestion that the asymmetrical sawtooth pattern is an artifact of viscous remanent remagnetization.
