CP - COUNTRY OF PUBLICATION: United-States PY - PUBLICATION YEAR: 1984 LA - LANGUAGE: English AB - ABSTRACT: Mean relative P wave (1 s) amplitude characteristics are determined for standardized seismic stations in the United States. Data are compiled from three azimuths: to the north, explosions in Russia; to the northwest, earthquakes along the Asian-Pacific arc; and to the south-southeast, earthquakes in South America. Characteristic receiver amplitudes are found to be azimuthally dependent. High-amplitude areas occur in the central United States, and lowest amplitudes occur along the Rocky Mountain front range and the Rio Grande rift zone. Amplification effects of low-velocity sediments are significant in the central United States. Azimuthal amplitude variations in the eastern United States are consistent with an anomalous attenuating or defocusing body in the lower mantle beneath Colombia, South America. Nonazimuthal amplitude studies are tied to the azimuthal data set to increase station amplitude coverage. Assuming that the variations of anelastic attenuation occur in the upper 400 km of the Earth, high-amplitude stations may be unattenuated, low-amplitude stations are consistent with Q approximately 110, and a mean amplitude implies Q approximately 220-240. The range of variation of Q is mapped into temperature variations, assuming a thermally activated Q mechanism and an olivine activation energy for the upper mantle. The apparent Q variations are consistent with temperature variations of 135 degrees -287 degrees C between high- and low-amplitude seismic station sites.--Modified journal abstract.

This new unit, for which the authors propose the name "Amoya Formation", crops out in the valleys of the Amoya and Ambeima rivers, and in the Quebrada Grande, to the W of Chaparral. It consists of a monotonous black pelite sequence with sporadic intercalations of fine-grained quartzose sandstones which appear to have suffered intense diagenesis or incipient regional metamorphism (angiometamorphism). The unit is cut by dikes and porphyritic bodies, which represent the roots of the overlying Saldana Formation volcanites. The thickness of the outcropping series reaches several hundred meters.

In addition to the turbidity currents, slumping along the continental slope and elsewhere also influence sedimentation in the fan.
