Three-dimensional density model of the upper mantle in the Middle East: interaction of diverse tectonic processes. J. Geophys. Res. 121 (7), 5349-5364.Kaban, M. K., El Khrepy, S., Al-Arifi, N., Tesauro, M., and Stolk, W. (2016c). Three-dimensional density model of the upper ...
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 velocity and density rather than Birch's relation between the velocity of compressional waves and density...
The possible density inversion throughout seismic wave-guides beneath ocean basins and continental structures (without shields) is discussed in accordance with upper-mantle velocity models, thermodynamic properties of deep matter and temperature profiles. The problem is numerically solved. No density inversi...
Hence the Williamson-Adams equation cannot be used in this part of the earth to derive the density variation from seismic data. In this paper the density in the upper mantle is obtained by explicitly introducing the constitution of the material there. In the lower mantle the extended Williamson...
The results show that:(1)the density anomaly of whole mantle is negative;(2)the density anomalies are strong in the region of most upper mantle and ne. 利用Su、Vasco、Hilst、Grand等提供的地震层析成像模型 ,根据实验室结果外推得到的地震波速度异常与密度异常之间的线性关系 ,将地幔进行分层、网格化...

Thermal structure and thickness of the lithospheric mantle underlying the Siberian Craton from the kraton and kimberlit superlong seismic profiles A self-consistent approach is proposed for the investigation of the thermal conditions, chemical composition, and internal structure of the upper mantle of....
Recently, plume-like anomalies were detected to exhibit different types of anomalous behavior at ∼1000 km depth, where they laterally pond, neck or broadly penetrate to the upper mantle, suggesting that their behavior may be influenced by possible viscosity or density stratification near this ...
