Cenozoic unconformities and depositional supersequences of North Atlantic continental margins: Testing the Vail model Cenozoic unconformities and depositional supersequences of North Atlantic continental margins: Testing the Vail model
Integrated outcrop, borehole, and seismic reflection stratigraphy from the U.S. and Irish margins of the North Atlantic basin reveals a framework of Cenozoic depositional supersequences and interregional unconformities that resembles the Vail depositional model. Paleo-bathymetric and paleoceanographic analyses of associated microfossil assemblages indicate a genetic link between the...

The Steens Mountain (Oregon) geomagnetic polarity transition: 3. Its regional significance The Steens Mountain (Oregon) geomagnetic polarity transition: 3. Its regional significance
Study of the variations of direction and intensity of the geomagnetic field as recorded by the Miocene lava flows on Steens Mountain, southeastern Oregon, has resulted in a detailed description of total field behavior during a reversal in polarity. In addition to information about the polarity reversal itself, the detailed paleomagnetic record includes several thousand years of...

Reflections from midcrustal rocks within the Mesozoic subduction complex near the eastern Aleutian Trench Reflections from midcrustal rocks within the Mesozoic subduction complex near the eastern Aleutian Trench
Seismic reflection data collected in 1973 by Western Geophysical Company show that highly reflective rocks make up the midcrust of the convergent margin adjacent to the eastern Aleutian Trench. These rocks form an arch that strikes obliquely across the strongly expressed northeast-southwest structural grain of exposed Mesozoic rocks. In an earlier report we proposed that the deep events...

The crustal structure of the axis of the Great Valley, California, from seismic refraction measurements The crustal structure of the axis of the Great Valley, California, from seismic refraction measurements
In 1982 the U.S. Geological Survey collected six seismic refraction profiles in the Great Valley of California: three axial profiles with a maximum shot-to-receiver offset of 160 km, and three shorter profiles perpendicular to the valley axis. This paper presents the results of two-dimensional raytracing and synthetic seismogram modeling of the central axial profile. The crust of the...

DEFORESTATION AND LANDSLIDES IN YUNNAN, CHINA. DEFORESTATION AND LANDSLIDES IN YUNNAN, CHINA.
Landslides historically have caused severe erosion problems in the Xiao River drainage region of northeastern Yunnan Province, China, that hence resulted in serious economic and social consequences. Owing to monsoonal storms of high rainfall intensity, the erosion potential is high in this mountainous, seismically active region. Landslides transported large quantities of materials into...

Sedimentary deposits in the northern lowland plains, Mars Sedimentary deposits in the northern lowland plains, Mars
The lowland plains on Mars have surfaces marked by large polygonal fracture patterns. It was recently proposed that the fracture patterns were developed on sedimentary deposits from outflow channels. We support this hypothesis because of the following observations. (1) Polygonal fracture patterns tend to occur in low areas on Mars that apparently received influx of sediments; the area of...

Crustal structure of Yunnan Province, People's Republic of China, from seismic refraction profiles Crustal structure of Yunnan Province, People's Republic of China, from seismic refraction profiles
Seismic refraction, profiles in Yunnan Province, southwestern China, define the crustal structure in an area of active tectonics on the southern end of the Himalaya-Burma arc. The crustal thickness ranges from 38 to 46 kilometers, and the relatively low mean crustal velocity indicates a crustal composition compatible with normal continental crust and consisting mainly of meta-sedimentary...
