Pre-existing faults in the mechanical basement are believed to play an important role controlling deformation of thin-skinned Jura Mountains fold-and-thrust belt, which constitutes northernmost extension European Alps. We use brittle-viscous analogue models investigate influence frontal and oblique steps on subsequent evolution structures during shortening. Vertical offset between two rigid bas...

The Paramirim Aulacogen was filled by the Espinhaço and São Francisco supergroups in period from 1.75 to 0.69 Ga, suffered partial inversion during Ediacaran. In northern sector of intracontinental domain Araçuaí-WestCongo Orogen, six compressive deformational phases were interpreted associated with frontal Aulacogen. Three structural domains identified: Jacaraci Fold-Thrust Belt, Caetité Nappe...

Inherited and syn-compressional salt-controlled structures in orogens are difficult to distinguish from compressional features because classical salt (halokinetic growth strata, welds) can be misinterpreted as shortening-related (syn-kinematic tectonic unconformities). In the Sivas basin Turkey, syn-kinematic diapirism entirely shaped architecture of foreland allowed development primary seconda...

The article considers the geological framework of a large orogenic structure in northeastern Eurasia - Verkhoyansk fold-and-thrust belt (VFTB), formed Late Mesozoic on eastern margin Siberian craton. Zoning geopotential fields and authors' interpretation frequency-energetic characteristics along 3-DV reference geo-physical profile provided basis for modeling deep VFTB adjacent structures There ...

Abstract Several orogenic belts exhibit regional-scale anticlines characterized by prominent faults in their crestal/forelimb zone. These are also a common feature the Neogene fold-and-thrust belt of Apennines, where they have been contrastingly interpreted as younger-on-older thrust faults, large-scale strike-slip and pre- or syn-thrusting normal faults. In this study, we analysed NW–SE-trendi...
