Heterogeneity and anisotropy in the lithospheric mantle [PDF]
Tectonophysics, 2015 The lithospheric mantle is intrinsically heterogeneous and anisotropic. These two properties govern the repartition of deformation, controlling intraplate strain localization and development of new plate boundaries. Geophysical and geological observations provide clues on the types, ranges, and characteristic length scales of heterogeneity and ...

Earth and Planetary Science Letters, 2019 Cratons are the most ancient parts of continents that are underlain by thick, cold, old and refractory lithospheric roots. However, how cratonic roots remain stable for billions of years and become remobilized later is still not well understood.

The Buoyancy of Cratonic Lithospheric Mantle
Geophysical Research LettersCratons 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.

Geochemistry, Geophysics, Geosystems, 2018 The role of lithospheric architecture and the mantle in the genesis of iron oxide copper‐gold (IOCG) deposits is controversial. Using the example of the Precambrian Gawler Craton (South Australia), which hosts the giant Olympic Dam IOCG deposit, we ...

Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical 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.

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