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

Cenozoic tectonic inversion in the Naglfar Dome, Norwegian North Sea

Marine and Petroleum Geology, 2020
Abstract Extensional settings with multiple phases of rifting are often intermitted by compressional tectonics or inversion. Differentiating compressional structures/phases in such settings become difficult when magma-induced forced folds are also present.

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.

Cenozoic tectonic inversion in the Northern Depression, South Yellow Sea Basin, East Asia: Structural styles and driving mechanism

Tectonophysics, 2021
International audienceThe Northern Depression of the South Yellow Sea Basin underwent two episodes of tectonic inversion from the latest Eocene to Oligocene and in the Pliocene, respectively.

Tectonic Inversion in East Africa

1999
Abstract Tectonic inversion has affected the Rukwa, Turkana, and Anza Graben areas to some degree. It is weakest in the Rukwa Rift where anticlines, probably of various origins, provide ambiguous evidence for inversion. In the Turkana area evidence for inversion is strong.

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 ...

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 ...
