The last erosional stage of the Molasse Basin and the Alps

Schlunegger, Fritz ; Mosar, Jon

In: International Journal of Earth Sciences, 2011, p. 1-16

We present a synoptic overview of the Miocene-present development of the northern Alpine foreland basin (Molasse Basin), with special attention to the pattern of surface erosion and sediment discharge in the Alps. Erosion of the Molasse Basin started at the same time that the rivers originating in the Central Alps were deflected toward the Bresse Graben, which formed part of the European Cenozoic...

Cenozoic-Recent tectonics and uplift in the Greater Caucasus: a perspective from Azerbaijan

Mosar, Jon ; Kangarli, Talat ; Bochud, Martin ; Glasmacher, Ulrich A. ; Rast, Annick ; Brunet, Marie-Francoise ; Sosson, Marc

In: Geological Society, London, Special Publications, 2010, vol. 340, p. 261-280

The Greater Caucasus is Europe's highest mountain belt and results from the inversion of the Greater Caucasus back-arc-type basin due to the collision of Arabia and Eurasia. The orogenic processes that led to the present mountain chain started in the Early Cenozoic, accelerated during the Plio-Pleistocene, and are still active as shown from present GPS studies and earthquake distribution. The...

Western Alps geological constraints on western Tethyan reconstructions

Stampfli, G. M. ; Borel, Gilles D. ; Marchant, R. ; Mosar, Jon

In: Journal of the Virtual Explorer, 2002, vol. 8, p. 77-106

Reconstructions of the Tethyan realm have been a matter of debate for a long time. Controversies spring usually from a lack of well constrained geological data which can be interpreted in different ways, or, from a lack of constraints on the plate tectonics framework. The western Alps region tends to escape these shortcomings due to a wealth of geological data regarding for examples the...

North Atlantic sea-floor spreading rates: implications for the Tertiary development of inversion structures of the Norwegian–Greenland Sea

Mosar, Jon ; Lewis, Gavin ; Torsvik, Trond H.

In: Journal of the Geological Society, 2002, vol. 159, no. 5, p. 503-515

Tertiary development of the Norwegian continental margin was dominated by the opening of the Arctic–North Atlantic Ocean. The correct identification of magnetic anomalies and their ages and the analysis of spreading rates during the formation of this ocean are important in understanding the development of the region and specifically the history of its passive margins. Three ocean domains,...

Present-day and future tectonic underplating in the western Swiss Alps: reconciliation of basement / wrench-faulting and décollement folding of the Jura and Molasse basin in the Alpine foreland

Mosar, Jon

In: Earth and Planetary Science Letters, 1999, vol. 173, no. 3, p. 143-155

The western Alps form a geodynamically active mountain belt showing the typical features of an evolving orogenic wedge with its pro-wedge geometry to the NNW and its retro-wedge structures to the SSE. Renewed tectonic underplating of European continental crust occurred after the orogenic wedge underwent major dynamic disequilibrium following the break-off of the southward subducting slab of the...
