Topographic Evolution and Climate Aridification during Continental Collision: Insights from Computer Simulations

How do the feedbacks between tectonics, sediment transport and climate work to shape the topographic evolution of the Earth? This question has been widely addressed via numerical models constrained with thermochronological and geomorphological data at scales ranging from local to orogenic. Here we present a novel numerical model that aims at reproducing the interaction between these processes a...

Active continental extension : The Woodlark Basin

n October 1995, a four-day multi channel seismic and bottom sampling survey was conducted aboard the R/V Ewing in the Pacific’s western Woodlark Basin. This site augmentation effort, supported by USSSP, was associated with JOIDES Proposal #447. New data from this survey provide further evidence for active extension on a low-angle (~25) normal fault but do not support a metamorphic core complex ...

Rift migration explains continental margin asymmetry and crustal hyper-extension

When continents break apart, continental crust and lithosphere are thinned until break-up is achieved and an oceanic basin is formed. The most remarkable and least understood structures associated with this process are up to 200 km wide areas of hyper-extended continental crust, which are partitioned between conjugate margins with pronounced asymmetry. Here we show, using high-resolution thermo...

XIer2 is required for convergent extension movements during Xenopus development.

Immediate early response 2 (Ier2) is a downstream target of fibroblast growth factor (FGF) signaling. In zebrafish, Ier2 is involved in left-right asymmetry establishment and in convergent extension movements. We isolated the Xenopus ier2 gene based on sequence similarity searches using multiple vertebrate species. Xenopus Ier2 has high homology in the N-terminal region to other vertebrate Ier2...

Fjord insertion into continental margins driven by topographic steering of ice

Fjords commonly punctuate continental edges formerly occupied by Quaternary ice sheets, reaching kilometre depths and extending many tens of kilometres inland. These features must have been created by late Cenozoic ice sheets, because rivers cannot erode bedrock much below sea level. Ice sheets drain primarily through fjords; therefore, widespread fjord insertion may have altered ice-sheet size...
