Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Fault evolution in the Potiguar rift termination, equatorial margin of Brazil [PDF]

open access: yesSolid Earth, 2015
The transform shearing between South American and African plates in the Cretaceous generated a series of sedimentary basins on both plate margins. In this study, we use gravity, aeromagnetic, and resistivity surveys to identify architecture of fault ...

Meso-Neoproterozoic tectono-thermal evolution in the northern margin of North China Craton: Constraints from zircon (U-Th)/He ages

open access: yesDizhi lixue xuebao, 2022
Due to the complicated tectonic and sedimentary history and the lack of effective paleo-thermal indicators, the Meso-Neoproterozoic thermal history of the Yanliao rift zone in the northern margin of the North China Craton is ambiguous, which causes the ...

Middle East Rift Zones [PDF]

open access: yesNature, 1969
EARLIER this year we proposed a model for the evolution of the Middle East rift zones1. In this it was shown that the motion, of the three major crustal plates, Nubia, Somalia and Arabia, was such that it could be described as rotational about a single pole, the differing rates of rotation producing the intervening rift zones.

Seismotectonics of Mongolia and Baikal Rift Zone Controlled by Lithospheric Structures

open access: yesGeophysical Research Letters, 2022
Active tectonics are developing in Mongolia and the Baikal rift zone, where large crustal earthquakes (Mw ≥ 6.0) occur frequently. To clarify the mechanism of these earthquakes, we determine a high‐resolution 3‐D P‐wave velocity model of the crust and ...

Extension parallel to the rift zone during segmented fault growth: application to the evolution of the NE Atlantic [PDF]

open access: yesSolid Earth, 2017
The mechanical interaction of propagating normal faults is known to influence the linkage geometry of first-order faults, and the development of second-order faults and fractures, which transfer displacement within relay zones.

Detection of Magma Beneath the Northern and Southern Rift Zones of Axial Seamount at the Juan de Fuca Ridge

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Axial Seamount is an active hotspot‐related volcanic system located along the Juan de Fuca Ridge (JdFR) that includes a central volcano and bounding northern and southern rift zones (NRZ and SRZ).

Assessing the potential of syn-rift sediments for geochronological dating and its implications for the development of Makanjira-Shire basin in south Malawi Rift

open access: yesQuaternary Science Advances, 2023
The Upper Shire River basin, located within the zone of progressive interaction and linkage between the southern Malawi Rift and Shire Rift Zone, East Africa, presents an early-stage rift setting where rapid denudation processes take place and have ...

Body‐Wave Tomographic Imaging of the Turkana Depression: Implications for Rift Development and Plume‐Lithosphere Interactions

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The Turkana Depression, a topographically subdued, broadly rifted zone between the elevated East African and Ethiopian plateaus, disrupts the N–S, fault‐bounded rift basin morphology that characterizes most of the East African Rift.

Geoelectric structure of northern Cambay rift basin from magnetotelluric data

open access: yesEarth, Planets and Space, 2017
Broadband and long-period magnetotelluric data were acquired over the northern part of the Cambay rift zone along an east–west profile ~ 200 km in length.
