Seismic constraints on the three-dimensional geometry of low-angle intracrustal reflectors in the Southern Iberia Abyssal Plain

, 2008
Several lines of evidence suggest that simple shear rifting of the continental crust, in the formof low-angle detachment faulting, occurred during the final stages of continental breakupbetween West Iberia and the Grand Banks.

Will present day glacier retreat increase volcanic activity? Stress induced by recent glacier retreat and its effect on magmatism at the Vatnajokull ice cap, Iceland [PDF]

, 2008
Global warming causes retreat of ice caps and ice sheets. Can melting glaciers trigger increased volcanic activity? Since 1890 the largest ice cap of Iceland, Vatnajokull, with an area of similar to 8000 km(2), has been continuously retreating losing ...

Rift Valley Fever [PDF]

Clinics in Laboratory Medicine, 2017
Rift Valley fever (RVF) is a severe veterinary disease of livestock that also causes moderate to severe illness in people. The life cycle of RVF is complex and involves mosquitoes, livestock, people, and the environment. RVF virus is transmitted from either mosquitoes or farm animals to humans, but is generally not transmitted from person to person ...

The Southwestern Rift of Africa: isotopic evidence of early-stage continental rifting

Frontiers in Earth Science
Helium and carbon isotope data (3He/4He = 0.14–0.17 R/Ra; δ13C(CO2) = −3.9‰) from hydrothermal springs within the Kafue Rift of Zambia provide the first geochemical characterization of thermal springs along a broad extensional zone connecting the African

Is There a Speed Limit for the Thermal Steady‐State Assumption in Continental Rifts?

Geochemistry, Geophysics, Geosystems, 2021
The lithosphere is often assumed to reside in a thermal steady‐state when quantitatively describing the temperature distribution in continental interiors and sedimentary basins, but also at active plate boundaries.

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]

, 2008
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

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

Tectonics, 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.

Sea-floor tectonics and submarine hydrothermal systems [PDF]

, 2005
The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

LONG-LIVED STRUCTURAL ENSEMBLES OF THE EAST EUROPEAN PLATFORM. Article 2. THE STRUCTURE OF THE TOP OF THE BASEMENT

Известия высших учебных заведений: Геология и разведка, 2018
The basement’s top tectonics of the East European platform (EEP) has been considered on the basis of the modern mapping data. The importance of the long-lived tectonic zones that form the vortex megastructure has been justified.Their Riphean — early ...
