The Changing Face of the Lithosphere‐Asthenosphere Boundary: Imaging Continental Scale Patterns in Upper Mantle Structure Across the Contiguous U.S. With Sp Converted Waves

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Juxtaposed terranes of highly varied tectonic history make up the contiguous U.S.: the tectonically active western U.S., the largely quiescent Archean and Proterozoic cratons of the central U.S., and the Phanerozoic orogen and rifted margin of the ...

Permian Large Igneous Provinces and Their Paleoenvironmental Effects

open access: yesGeophysical Monograph Series, Page 417-434., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Corona structures driven by plume–lithosphere interactions and evidence for ongoing plume activity on Venus

open access: yesNature Geoscience, 2020
In the absence of global plate tectonics, mantle convection and plume–lithosphere interaction are the main drivers of surface deformation on Venus. Among documented tectonic structures, circular volcano-tectonic features known as coronae may be the ...

Lithospheric folding in Iberia [PDF]

open access: yesTectonics, 2002
Integration of stress indicator data, gravity data, crustal kinematics data, and analysis of topography and recent vertical motions demonstrates the occurrence of consistently oriented spatial patterns of large‐scale Alpine to recent intraplate deformation in Iberia. The inferred upper crustal and lithospheric deformation patterns and the timing of the

Insolation driven variations of Mercury’s lithospheric strength [PDF]

open access: yes, 2010
Mercury's coupled 3:2 spin-orbit resonance in conjunction with its relatively high eccentricity of ~0.2 and near-zero obliquity results in both a latitudinal and longitudinal variation in annual average solar insolation and thus equatorial hot and cold ...

Lithospheric failure on Venus [PDF]

open access: yesProceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003
Summary: We develop a predictive model which has the ability to explain a postulated style of episodic plate tectonics on Venus, through the periodic occurrence of lithospheric subduction events. Present-day incipient subduction zones are associated with the existence of arcuate trenches on the Venusian lithosphere.

Smart Speed Imaging in Digital Image Correlation: Application to Seismotectonic Scale Modeling

open access: yesFrontiers in Earth Science, 2019

Geodynamic evolution of a wide plate boundary in the Western Mediterranean, near-field versus far-field interactions

open access: yesBSGF - Earth Sciences Bulletin, 2021
The present-day tectonic setting of the Western Mediterranean region, from the Pyrénées to the Betics and from the Alps to the Atlas, results from a complex 3-D geodynamic evolution involving the interactions between the Africa, Eurasia and Iberia plates
