Links Between Faulting, Topography, and Sediment Production During Continental Rifting: Insights From Coupled Surface Process, Thermomechanical Modeling

From Lithospheric Thickening and Divergent Collapse to Active Continental Rifting

Time-calibrated models support congruency between Cretaceous continental rifting and titanosaurian evolutionary history.

Recent model-based phylogenetic approaches have expanded upon the incorporation of extinct lineages and their respective temporal information for calibrating divergence date estimates. Here, model-based methods are explored to estimate divergence dates and ancestral ranges for titanosaurian sauropod dinosaurs, an extinct and globally distributed terrestrial clade that existed during the extensi...

Synchronous oceanic spreading and continental rifting in West Antarctica

Magnetic anomalies associatedwith new ocean crust formation in the Adare Basin off north-western Ross Sea (43–26Ma) can be traced directly into the Northern Basin that underlies the adjacent morphological continental shelf, implying a continuity in the emplacement of oceanic crust. Steep gravity gradients along the margins of the Northern Basin, particularly in the east, suggest that little ext...

Rifting and subsidence following lithospheric removal in continental back arcs

It has been suggested that post-orogenic lithospheric removal in continental back arcs promotes extension and surface subsidence. However, the surface response of this process and its primary difference from “classical” back-arc opening have remained uncertain. Here, the back-arc extension process with varying continental mantle lithosphere thickness and thermal heterogeneities is studied by us...
