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.

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.

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.

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 ...

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 ...

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 controls on the Karlıova triple junction (Turkey): Implications for tectonic inversion and the initiation of volcanism

Tectonophysics, 2017
Abstract Few places on Earth are tectonically as active as the Karliova region of eastern Turkey which comprises a triple junction (KTJ). Triple junctions result in complex kinematic and mechanical interactions within the lithosphere generating tectonic inversions and uplift, extensive seismicity and volcanism. Here we present new data, and summarize

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.

The inverse problem in microtectonics and the separation of tectonic phases

Tectonophysics, 1982
Abstract The algorithm of inverse problems is applied to three cases in microtectonics. A collection of striations measured on pre-existing faults may be processed automatically and interpreted in terms of tectonic stress. A comparison is made between two different methods formerly proposed by the authors. Both methods are tested with field data. The

Extensional structures and their tectonic inversion in the Western Alps

Geological Society, London, Special Publications, 1991
Abstract During Alpine collision the western margin of Tethys was uplifted on large-scale thrust zones, to preserve and give excellent 3D exposures of Mesozoic fault geometries. The faults are particularly well exposed along the margins of the Belledonne and Pelvoux basement massifs, east of Grenoble.
