An Earth model consistent with free oscillation and surface wave data
Density and constitution of the mantle
Available experimental data for some rock-forming minerals indicate that, for the prediction of density in the upper mantle, it may be preferable to use an empirical relation between bulk sound…
Seismological Evidence for Heterogeneity of the Mantle
The latest results concerning the depth variation of Q, P- and S-wave velocities obtained by various seismological methods are reviewed with special emphasis on the regional variation. The body-wave…
Upper mantle models from ‘pure‐path’ dispersion data
‘Pure-path’ phase and group velocities of mantle Rayleigh waves in combination with mantle Love wave velocities and worldwide averages of free oscillation data are used to derive upper mantle models…

Shear wave velocities in the Earth's mantle
Mantle heterogeneities, geoid, and plate motion: A Monte Carlo inversion
Seismic tomography in both the upper and the lower mantle, as well as subducting oceanic slabs defined by seismicity, has been translated into density heterogeneities to generate models of mantle…
Geological interpretation of the gravity data for a profile across the Pacific Ocean
This paper presents a model of geological interpretation of gravity observations along the profile across the Pacific Ocean from the Japan trench across the Hawaiian ridge to the Middle America…
Temperature Field and Geophysical Effects of a Downgoing Slab
The factors affecting the thermal behavior of a lithospheric slab descending into the mantle are so numerous and complicated that only numerical methods can accurately account for them. A series of…
Generalized structure and composition of the deep crust and upper mantle in Canada
Throughout most of Canada the regional Bouguer anomaly is inversely proportional to the depth of the crust-mantle boundary; the constant of proportionality indicates that the density contrast at the…

Array measurements of P velocities in the upper mantle
The extended array at the Tonto Forest Seismological Observatory in central Arizona has been used to measure dT/dΔ of direct P waves from 212 earthquakes in the distance range between 30 and 100°,…
Earth models obtained by Monte Carlo inversion.
The problem of uniqueness of earth structures obtained by the inversion of geophysical data is still unsolved. Monte Carlo methods offer the advantage of exploring the range of possible solutions and…
Density distribution and constitution of the mantle
Major regions of inhomogeneity are present in the mantle at depths less than 1000 km. The thermal gradient also greatly exceeds its adiabatic value at relatively shallow depths. Hence the…
Density Distribution in Earth
TLDR
Earth models selected by a Monte Carlo procedure were tested against geophysical data and six have passed all tests; common features of successful models are an increased core radius and a chemically inhomogeneous core consistent with Fe-Ni alloy.
Phase velocities of long‐period surface waves and structure of the upper mantle: 1. Great‐Circle Love and Rayleigh wave data
New long-period dispersion data are obtained from the surface waves generated by the Alaska earthquake of March 28, 1964, and recorded at Isabella, Kipapa, and Stuttgart. Digital techniques were used…
Partial melting in the upper mantle
Elasticity and constitution of the Earth's interior
The observed variation of the seismic velocities with depth, below the crust, is examined with reference to the variation to be expected in a homogeneous medium. A general equation is derived for the…
Observed Attenuation and Q Values of Seismic Surface Waves in the Upper Mantle
Attenuation coefficients and Q values of Love and Rayleigh waves in the period range 50–330 sec have been derived from the amplitude spectrums of these waves. Data were obtained from surface wave…
Temperature and discontinuities in the transition layer within the Earth's mantle: Geophysical application of the olivine‐spinel transition in the Mg2SiO4‐Fe2SiO4 System
The nature of the transition layer (the C layer) is considered with the homogeneous chemical composition, model. The physical properties of the transition layer are determined essentially by the…
Composition of the Earth's Mantle
Summary Measurements of the velocity of compressional waves in silicates and oxides having a range of density from 2.6 to 5g/cm3 suggest a simple dependence of velocity upon density and mean…
