The Alps in the Cretaceous: a doubly vergent pre‐collisional orogen

Terra Nova, 2012
Terra Nova, 24, 351–356, 2012AbstractCurrent palaeotectonic models see the Alps chiefly as a collisional orogen, with the Southalpine retrobelt developed only as a post‐collisional feature. New structural and geochronological data show, instead, that the continental margin of Africa‐Adria was being structured as a doubly vergent orogen during ...

A geophysical model of the Variscan orogenic root (Bohemian Massif): Implications for modern collisional orogens

Lithos, 2011
Abstract A new model of the structure and composition of the Variscan crust in the Bohemian Massif is proposed based on 3D gravity modelling, geological data, seismic refraction (CEL09) and reflection (9HR) sections. The Bohemian Massif crust is characterized by a succession of positive and negative anomalies of about 60–80 km wavelength for nearly ...

Late-orogenic backfolding and extension in the Brooks Range collisional orogen, northern Alaska

Journal of Structural Geology, 2002
Abstract New structural observations across a crustal section spanning relatively unmetamorphosed fold–thrust belt rocks and epidote–amphibolite grade rocks document the late-orogenic kinematic history of the Brooks Range, Alaska, and provide insight into the character, relative timing, and geodynamic setting of late-orogenic backfolding and ...

Proterozoic collisional tectonism in the Trans-Hudson orogen, Saskatchewan

Geology, 1990
Isotopic and structural data from the juvenile Reindeer zone of the Trans-Hudson orogen, northern Saskatchewan, indicate a pre-1.85 Ga thermotectonic event, possibly reflecting arc-continent collision, followed by a more extensive, nappe-forming, ca. 1.83-1.80 Ga thermotectonism during terminal continent-continent collision.

Asymmetric exhumation across the Pyrenean orogen: implications for the tectonic evolution of a collisional orogen

Earth and Planetary Science Letters, 1999
Abstract The Pyrenees are a collisional mountain belt formed by convergence between the Afro–Iberian and European plates. Apatite fission track thermochronology from three vertical profiles along the ECORS seismic line constrain the exhumation history of the Pyrenean orogen and hence tectonic models for its formation.
