United States crustal thickness
Tectonophysics, 1983The thickness of the crust, the thickness of the basal (intermediate or lower) crustal layer, and the average velocity at the top of the mantle have been mapped using all available deep-penetrating seismic-refraction profiles in the conterminous United States and surrounding border areas. These profiles are indexed to their literature data sources. The

A relationship between crustal thickness and mean crustal velocity
Tectonophysics, 1989Abstract Variable parameters of the continental crust are: crustal age, heat flow, reflectivity, thickness and velocity. While heat flow and reflectivity decrease, crustal thickness increases with age. For stable crustal regions we present a correlation between crustal thickness and mean crustal velocity. The evaluation is based on more than 270 data

Crustal thickness of northeast Russia
Tectonophysics, 1998Abstract The first-order crustal structure of the Magadan region and northeast Sakha Republic (Yakutia), northeast Russia, is obtained by simultaneously inverting for origin times and travel time curves. A total of 1210 observations are used. As an average, a 37-km-thick, 5.992±0.007 km/s crust overlying an 7.961±0.015 km/s mantle provides an ...

New crustal-thickness results for Fennoscandia
Geologiska Föreningen i Stockholm Förhandlingar, 1981Abstract The spectral ratio technique of Phinney, R. A., 1964: Structure of the earth's crust from spectral behavior of long period body waves (Journal of Geophysical Research 69, 29973017) has been used for estimating crustal thickness beneath 11 Fennoscandian seismograph stations equipped with three-component long period instruments.

A new global crustal thickness map
Tectonics, 1982An up‐to‐date global compilation of crustal thickness and Pn velocity values from published seismic refraction and surface wave data has been created. From 297 referenced sources, a total of 2508 crustal thickness and 1806 Pn velocity values have been selected. This represents a significant expansion of previous compilations.

Gravity-inferred crustal thickness of Greenland
Earth and Planetary Science Letters, 2007Abstract Greenland's crust contains clues for understanding the dynamics of the Earth's second largest ice-sheet, as well as the Iceland hotspot over the past 100 Ma. However, our knowledge of the sub-ice crust is very limited due to the paucity of outcrops and seismic observations, particularly in central Greenland.

Oceanic spreading rate and crustal thickness
Marine Geophysical Researches, 1981Examination of oceanic seismic refraction results indicates a correlation between total crustal thickness and spreading rate, with slower spreading producing thinner crust. The effect is seen at spreading rates less than about 20 mm yr−1. The crustal thickness and its dependence on spreading rate are predicted by theoretical modelling of flow and ...

Crustal thickness variation in south-central Alaska
Geology, 2006Crustal thicknesses have been determined by receiver function analysis of broadband teleseismic waveforms recorded during the Broadband Experiment Across the Alaska Range (BEAAR). Typical crust beneath the northern lowlands is 26 km thick, while beneath the mountains it is 35–45 km thick.

A Crustal Thickness Constraint for Central Pennsylvania
Seismological Research Letters, 1981The timing and amplitude of long-period Ps conversions observed on the radial component of ground motion from a suite of teleseismic events were used to place constraints on crustal structure under the WWSSN station SCP (State College, Pennsylvania). Radial P waveforms from impulsive deep earthquakes were modeled in the time domain after corrections ...

The crustal thickness of NE Tibet and its implication for crustal shortening
Tectonophysics, 2014Abstract The crustal deformation model for NE Tibet is key to understanding the outward growth of the plateau, especially along its northern front. This study describes receiver function images of the Moho beneath NE Tibet, as calculated from teleseismic data recorded by regional seismic networks.
