... the reflected wave field from a sum over discrete, spherical eigenfunctions to an integral over continuous wave numbers in a flat geometry. The far-field form of this integral shares many properties with the Weyl integral and is useful for body-wave studies in a spherical earth. Bulletin of the Seismological...

... METHOD 1021 (see Brekovskikh, 1980; Aki and Richards, 1980, for details) characterized by the exponential amplitude decay along the wave front. As these waves are present in the mathematical representation of the spherical wave in the form of Weyl or Sommerfeld integrals, the S* arrival may well...

... decomposition of the free-space Green's function. The latter can be found in many texts (e.g., Aki and Richards, 2002 , p. 192) where it is called the Weyl integral. For a source at the origin, the Weyl integral is given by (A-1) G ( 0 , x = ( x , y , z ) , v , ω ) = 1 R exp...

.... The youngest rocks that host entrenched meanders were deposited during the middle Miocene silicic ignimbrite flare-up event that blanketed the western third of northern Central America with as much as 2 km of strata ( Williams and McBirney, 1969 ; Weyl, 1980 ; Fig. 2 ). The Ar/Ar geochronology of ash...

... ( Aki and Richards, 2002 ). This approach faces various problems because the assumption of planar incident waves is reasonable only for weak contrasts, small incidence angles, and relatively smooth reflectors. It is a well-known fact that the plane-wave coefficients do not account for complex wave...

... dissertation was based on a study of a part of the northern, limestone Alps. Still troubled by his health, Sapper was advised to move to a warmer climate. His older brother, Richard, had gone to Guatemala in 1884 to join a group of German settlers, mainly Swabians, who were developing large coffee estates...

... pressure. IPS consists of pressure-induced dissolution along grain contacts, resulting in reduction of the pore volume. Hypotheses and the factors controlling the occurrence of pressure solution have been discussed previously ( Weyl, 1959 ; Tada and Siever, 1986 ; Houseknecht and Hathon, 1987 ; Moore...

...Heather A. Sheldon; John Wheeler; Richard H. Worden; Michael J. Cheadle Abstract Chemical compaction, also known as pressure solution, involves dissolution along grain contacts and transport of solute to the adjacent pore space by diffusion. The driving force for diffusion is a gradient in chemical...
