The African upper mantle and its relationship to tectonics and surface geology [PDF]
Geophysical Journal International, 2008 This paper focuses on the upper-mantle velocity structure of the African continent and its relationship to the surface geology. The distribution of seismographs and earthquakes providing seismograms for this study results in good fundamental and higher mode path coverage by a large number of relatively short propagation paths, allowing us to image the ...

The Deep Roots of Geology: Tectonic History of Australia and its Margins expressed by Mantle Anisotropy [PDF]
, 2021 Abstract The Australian continental crust preserves a rich geological history, but it is unclear to what extent this history is expressed deeper within the mantle. Scattering of surface waves predominantly between 100-200 km depth by lateral gradients in seismic anisotropy, termed Quasi-Love waves, offer potential new insights.

Integration of natural data within a numerical model of ablative subduction: A possible interpretation for the Alpine dynamics of the Austroalpine crust [PDF]
Journal of Metamorphic Geology, 2012, 2012 A numerical modelling approach is used to validate the physical and ge- ological reliability of the ablative subduction mechanism during Alpine con- vergence in order to interpret the tectonic and metamorphic evolution of an inner portion of the Alpine belt: the Austroalpine Domain.

The Deep Roots of Geology: Tectonic History of Australia Preserved as Mantle Anisotropy [PDF]
, 2021 Abstract Australia is an old stable continent with a rich geological history. Limitations in sub-surface imaging below the Moho, however, mean that is unclear to what extent, and to what depth, this rich geological history is expressed in the mantle.

Mantle dynamics in the Mediterranean
Reviews of Geophysics, 2014 The Mediterranean offers a unique opportunity to study the driving forces of tectonic deformation within a complex mobile belt. Lithospheric dynamics are affected by slab rollback and collision of two large, slowly moving plates, forcing fragments of ...

Geology, geochronology, and geochemistry of the Miocene–Pliocene Ancestral Cascades arc, northern Sierra Nevada, California and Nevada: The roles of the upper mantle, subducting slab, and the Sierra Nevada lithosphere [PDF]
Geosphere, 2008 The assemblage of ca. 28–3 Ma volcanic rocks exposed in the Lake Tahoe–Reno region of the northern Sierra Nevada, United States, is interpreted to be part of the Ancestral Cascades volcanic arc. The volcanic rocks are commonly highly porphyritic, including abundant plagioclase with clinopyroxene, amphibole, and rare biotite, and range from basaltic ...
