Analogue Modelling of Inverted Oblique Rift Systems [PDF]

open access: yesGeologica Acta, 2005
The geometric evolution of brittle fault systems in inverted oblique and offset rift systems has been simulated using scaled sandbox analogue models. Dry fine-grained quartz sand was used to represent the brittle upper crust.

Inversion tectonics during continetal rifting : The Turkana Cenozoic rifted zone, northern Kenya [PDF]

open access: yesTectonics, 2005
International audienceRemote sensing data and revised seismic reflection profiles provide new insights about the origin of inverted deformation within Miocene-Recent basins of the Turkana rift (northern Kenya) in the eastern branch of the East African ...

Morphology of the Reykjanes ridge junction with the rift zones of Iceland

open access: diamondВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
The joint zone between subaquatic Reykjanes Ridge and Icelandic rift zones known as Reykjanes Rift Zone is a unique transform zone formed in conditions of interaction between the mantle plume and the mid-oceanic ridge.

Crustal and Upper Mantle Imaging of Botswana Using Magnetotelluric Method

open access: yesFrontiers in Earth Science, 2022
We used magnetotelluric data from 352 sites in Botswana to derive a country-wide electrical conductivity model of the crust and upper mantle structure. A robust methodological scheme and 3D inversion were used to derive a 3D electrical conductivity model

Geophysical prospecting of copper-nickel deposits in Beishan rift zone, Xinjiang

open access: yesChina Geology, 2021
: The Beishan rift zone in Xinjiang Uygur Autonomous Region was formed due to strong activities of faults on the basement of the Tarim continental crust.

GEODYNAMICS OF JOINT ZONES OF REYKJANES AND KOLBEINSEY SPREADING RIDGES WITH ICELAND RIFT ZONES

open access: yesГеодинамика и тектонофизика, 2023
Joint zones of Reykjanes and Kolbeinsey spreading ridges with Iceland large igneous province considerably differ in structure from adjacent spreading segments despite of similar kinematics. Tjörnes transform zone is a complicated system.

Off-rift volcanism in rift zones determined by crustal unloading [PDF]

open access: yesNature Geoscience, 2014
When continents are stretched over a long period of time, deep elongated rift valleys form at Earth’s surface and zones of ponded magma, centred beneath the rift, form at the crust–mantle boundary1, 2. Ascending magma sometimes erupts within the rift valley3, 4 or, counterintuitively, at volcanic fields away from the rift valley that are offset by tens

Structural Inheritance Controls Strain Distribution During Early Continental Rifting, Rukwa Rift

open access: yesFrontiers in Earth Science, 2021
Little is known about rift kinematics and strain distribution during the earliest phase of extension due to the deep burial of the pre-rift and earliest rift structures beneath younger, rift-related deposits.

Tectonothermal Evolution of the Broadly Rifted Zone, Ethiopian Rift [PDF]

open access: yesTectonics, 2019
AbstractThe Broadly Rifted Zone (BRZ) of southern Ethiopia is a long‐lived and structurally complex segment of the East African Rift System. However, due to poor surface exposure of early synrift strata and a dearth of subsurface data, the evolution of the BRZ remains poorly understood.
