Southwest Pacific crustal structure

Eos, Transactions American Geophysical Union, 1955
This investigation has been concerned with the determination of the crustal thicknesses of the various features of the Southwest Pacific from Love‐ and Rayleighwave dispersion characteristics. The crustal thickness of the Tasman Basin between New Zealand and Australia is the same five to ten km, as that for the South Pacific Basin to the east of New ...

Crustal structure in the Transvaal*

Bulletin of the Seismological Society of America, 1956
abstract Travel-time data are given at 25 km. intervals between 50 and 500 km. for traverses west, south, east, and north of Johannesburg. These derive from numerous seismograms of Witwatersrand earth tremors taken by means of a triggering technique.

Arcuate Crustal Structures

1986
Abstract The orogenic ridges on continents and island arcs have a similar history of development and character of tectonic deformations. They also have much in common with the linear ridges. The arcuate shape of orogenic uplifts is associated with long geological history, during which the consecutively appearing structures overlaid one another or ...

Crustal structure from seismic exploration

Journal of Geophysical Research, 1954
The exploration of the earth's crust with seismic waves has an accuracy limited by conversion-scattering and the scattering of surface and interior irregularities. These scattering effects produce signals masking the smaller signals which might be present from minor structural features. Consequently, only the broader aspects of crustal structure may be

CRUSTAL STRUCTURE UNDER HUDSON BAY

Canadian Journal of Earth Sciences, 1967
A crystal refraction experiment was conducted in August 1965 in Hudson Bay in which nine university and government crews participated. Good quality data were obtained from 41 shots providing sufficient data to permit time-term analyses of both Pnand P1arrivals.

Crustal structure of northern Israel

Marine and Petroleum Geology, 1994
Abstract In the course of a seismic refraction/wide angle reflection experiment in the eastern Mediterranean, an east-west reversed refraction profile was recorded onshore northern Israel. The purpose of the line was to obtain reliable velocity and structural information about the crust in this area.

Truncated crustal transfer functions and fine crustal structure determination

Bulletin of the Seismological Society of America, 1967
abstract A seismic pulse is influenced by the various media through which it has travelled. The crust is known to have a considerable influence. With the use of the Thomson-Haskell matrix formulation, the crustal effect can be easily calculated.

Average crustal structure of Sweden

pure and applied geophysics, 1971
Records obtained at the permanent stations of the Swedish seismograph network from explosions carried out in Scandinavian waters in June 1969 are evaluated. The study includes determination of velocities for all crustal phases observed, furthermore of layer thicknesses, Poisson ratios and amplitude ratios.

Crustal Structure of Western Portugal

1983
Abstract Crustal investigations of Western Portugal, along the Mesozoic zone situated between Lisboa and Nazare, show the following major characteristics: in the uppermost 8 km the velocity increases continuously with increasing depth reaching the unusually high value of 6.5 km/s; this layer is underlain by a sialic low-velocity layer, probably ...
