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.

The Buoyancy of Cratonic Lithospheric Mantle [PDF]

open access: yesGeophysical Research Letters
Abstract Cratons are generally thought to be characterized by stable, long‐lived mantle roots. However, recent studies have suggested that the lithospheric mantle may be prone to removal, implying that it may be denser than the asthenosphere.

Modeling of the Arabian/Nubian shield’s geothermal structure: a multi-parametric analysis using geophysical and geological tools [PDF]

open access: yesScientific Reports
The Arabian-Nubian Shield (ANS) is a complex Neoproterozoic tectonic mosaic whose lithospheric structure and geothermal regime remain poorly constrained.

Heavy oxygen recycled into the lithospheric mantle. [PDF]

open access: yesSci Rep, 2019
AbstractMagmas in volcanic arcs have geochemical and isotopic signatures that can be related to mantle metasomatism due to fluids and melts released by the down-going oceanic crust and overlying sediments, which modify the chemistry and mineralogy of the mantle wedge.

Breakup of strong cratonic lithosphere causes extensive magmatism at continental margins [PDF]

open access: yesScientific Reports
Extensive magmatism and Large Igneous Provinces (LIPs) may form at continental margins during continental breakup. While high mantle temperatures and geochemical fertility (such as plume activity) are typically considered the causes of magmatic ...

Lithospheric mantle buoyancy: the role of tectonic convergence and mantle composition. [PDF]

open access: yesSci Rep, 2019
AbstractPlate subduction and delamination, two key processes driving plate tectonics, are thought to be controlled by the buoyancy of the lithospheric mantle relative to the underlying asthenosphere. Most mantle delamination models consider a lithospheric density higher than the asthenosphere to ensure negative buoyancy (slab pull).

Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]

open access: yes, 2006
Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

The Accuracy Assessment of Lithospheric Density Models

open access: yesApplied Sciences, 2023
The Earth’s synthetic gravitational and density models can be used to validate numerical procedures applied for global (or large-scale regional) gravimetric forward and inverse modeling.
