Inversion tectonics in central Alborz, Iran

Journal of Structural Geology, 2006
Abstract Structural analyses carried out in the southern-central Alborz (Iran) have shown that the evolution of this belt has been strongly conditioned by the inversion of pre-existent extensional faults. Inversion tectonics has been identified especially in the southern part of the belt, and it is related to the reactivation of grabens formed in the

Geometry and kinematics of inversion tectonics

Geological Society, London, Special Publications, 1989
Summary Positive inversion tectonics involves the reversal of extensional fault movement during contractional tectonics. Basin stratigraphy developed before, during and after extensional fault movements may be described as pre-, syn- and postrift sequences.

Sandbox model studies of inversion tectonics

Tectonophysics, 1987
Abstract Scaled plane-strain sandbox models have been used to simulate basement-controlled structural inversion in a sedimentary overburden. Two basement configurations were tested. In the first one, reversal of movement along vertical and normal faults that controlled a graben relief induced only a partial recovery of displacement along the pre ...

Mid-continent tectonic inversions, Northwest Territories, Canada

Journal of Structural Geology, 1996
Abstract Four types of tectonic inversion are recorded on reflection seismic data from the area northwest of Great Bear Lake in the Northwest Territories, Canada. The strata involved span about 1.7 Ga of Proterozoic and Phanerozoic history, and have been subjected to at least five tectonic events, two extensional, two compressional and one ...

Analogue models of inversion tectonics

Geological Society, London, Special Publications, 1989
Summary Inversion of dip-slip fault systems by horizontal recompression has been modelled using sand, sand-mica and sand-clay analogues. Three extension-inversion systems have been tested: uniform basal detachment, simple listric detachment and ramp/flat detachments.

Inversion tectonics in S.W. Dyfed

Proceedings of the Geologists' Association, 1987
Inverted sedimentary basins form when basin-controlling extensional faults reverse their movement during contractional tectonics. The structural evolution of S.W. Dyfed is considered in terms of a model of positive inversion tectonics. A change in deformation mode from Devonian extension to Late Carboniferous contraction gave rise to renewed movement ...

TECTONIC INVERSION OF THE DNIEPER-DONETS BASIN

2021
The structural deformations of the sedimentary cover of the Dnieper-Donets basin (DDB) of the stages of platform tectonic activation in the zone of its articulation with the Donets Foldbelt (DF) were studied. Based on the structural analysis of the geocarting materials of the territory of the Western Donets Graben (WDG), using field definitions of the ...

Tectonic inversion and structural inheritance in mountain belts

Journal of Structural Geology, 2006
Collisional mountain belts are the product of deformation of former continental margins. During the past 20 years it has be- come increasingly evident that the pre-existing faults, basin structures and the stratigraphic variations they generate can play a significant role in influencing the structural evolution of later compressional tectonics.
