الصفحة 391 - Bouguer gravity anomaly map of the United States (exclusive of Alaska and Hawaii) : Washington, DC, US Geol.
الصفحة 358 - A, p. 1855-1864, 1964. The attenuation of seismic waves is a direct measure of the absorption due to nonelastic processes in the Earth. The well known difficulties in obtaining body wave amplitude decrement data have been avoided by studying the spectral ratios of multiple ScS and sScS phases from two deep focus earthquakes recorded at near normal incidence. The average Q for shear in the mantle is about 600 for the frequency range 0.015-0.07 cycles per second.
الصفحة 58 - Res. v. 69, no. 20, p. 4319-4326, 1964. "A comparison of aeromagnetic profiles with bedrock geology in the McMurdo Sound area indicates high-amplitude anomalies associated with the McMurdo volcanics and no significant anomalies associated with rocks in the crystalline basement complex.
الصفحة 371 - An explicit expression is derived for the body force to be applied in the absence of a dislocation, which produces radiation identical to that of the dislocation. This equivalent force depends only upon the source and the elastic properties of the medium in the immediate vicinity of the source and not upon the proximity of any reflecting surfaces. The theory is developed for dislocations in an anisotropic inhomogeneous medium; in the examples isotropy is assumed. For displacement dislocation faults,...
