Interaction of Mantle Dregs with Convection: Lateral Heterogeneity at the Core-mantle Boundary
Preliminary numerical models indicate that chemically denser material (dregs) at the base of the mantle would have substantial lateral variations in thickness induced by convection of the overlying mantle, and might well form discontinuous aggregations below mantle upwellings. A model with a density contrast of about 2 per cent and an initial uniform thickness of the denser layer of 100 km yiel...
متن کاملCan we resolve 3D density heterogeneity in the lower mantle?
We reexamine the possibility of resolving 3D density structure in the mantle, by performing test inversions using a dataset of well constrained degree 2 splitting coefficients. We show that degree 2 in Vs and Vp can be resolved, and confirm that dlnVs/dlnVp >2.5 at depths > 2000km, indicating a chemical component to large scale heterogeneity. Models with p positively correlated with V• in the d...
متن کاملImplications of lower-mantle structural heterogeneity for existence and nature of whole-mantle plumes
Recent seismological studies demonstrate the presence of strong deep-mantle elastic heterogeneity and anisotropy, consistent with a dynamic environment having chemical anomalies, phase changes, and partially molten material. The implications for deep-mantle plume genesis are discussed in the light of the seismological findings. Nearly antipodal large low–shear velocity provinces (LLSVPs) in the...
متن کاملObservation of coronal loop torsional oscillation
We suggest that the global torsional oscillation of solar coronal loop may be observed by the periodical variation of a spectral line width. The amplitude of the variation must be maximal at the velocity antinodes and minimal at the nodes of the torsional oscillation. Then the spectroscopic observation as a time series at different heights above the active region at the solar limb may allow to ...
متن کاملSplitting of the 520-kilometer seismic discontinuity and chemical heterogeneity in the mantle.
Seismic studies indicate that beneath some regions the 520-kilometer seismic discontinuity in Earth's mantle splits into two separate discontinuities (at approximately 500 kilometers and approximately 560 kilometers). The discontinuity near 500 kilometers is most likely caused by the (Mg,Fe)2SiO4 beta-to-gamma phase transformation. We show that the formation of CaSiO3 perovskite from garnet can...
