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.

Analog and Numerical Modeling of Rift‐Rift‐Rift Triple Junctions

open access: yesTectonics, 2022
AbstractRift‐Rift‐Rift triple junctions are key features of emergent plate boundary networks during fragmentation of a continent. A key example of such a setting is the Afar triple junction where the African, Arabian and Somalian plates interact. We performed analog and numerical models simulating continental break‐up in a Rift‐Rift‐Rift setting to ...

Rifts in rafts

open access: yesSoft Matter, 2023
Particle rafts floating on expanding liquid substrates exhibit velocity-dependent failure morphology and provide an accessible model system for studying cluster formation and material failure across many scales from the microscopic to the celestial.

Rifting continents

open access: yes, 2022
Abstract. Continental rifts can form when and where continents are stretched. If the driving forces can overcome lithospheric strength, a rift valley forms. Rifts are characterised by faults, sedimentary basins, earthquakes and/or volcanism. With the right set of weakening feedbacks, a rift can evolve to break a continent into conjugate rifted margins ...

Origin and Age of Magmatism in the Northern Philippine Sea Basins

open access: yesGeochemistry, Geophysics, Geosystems, 2022
A Robust tectonic reconstruction of the Philippine Sea Plate around ∼52 Ma is a prerequisite in understanding the process of subduction initiation and establishment of the Izu‐Bonin‐Mariana arc.

Sedimentation and subsidence history of the Lomonosov Ridge [PDF]

open access: yes, 2006
During the first scientific ocean drilling expedition to the Arctic Ocean (Arctic Coring Expedition [ACEX]; Integrated Ocean Drilling Program Expedition 302), four sites were drilled and cored atop the central part of the Lomonosov Ridge in the Arctic ...

Asymmetric continental deformation during South Atlantic rifting along southern Brazil and Namibia [PDF]

open access: yes, 2017
Plate restoration of South America and Africa to their pre-breakup position faces the problem of gaps and overlaps between the continents, an issue commonly solved with implementing intra-plate deformation zones within South America.

Tectonic structure and conditions for the formation of the marginal plateau and Socotra Island (physical modeling). Part 1. Structure of the Socotra Island

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The structure of the eastern part of the Gulf of Aden is peculiar for the presence of a submerged plateau and the island of Socotra, which were formed at the initial stage of its formation.

Geochemistry and 40Ar/39Ar age of Early Carboniferous dolerite sills in the southern Baltic Sea [PDF]

open access: yesEstonian Journal of Earth Sciences, 2015
The Early Carboniferous magmatic event in the southern Baltic Sea is manifested by dolerite intrusions. The presumable area in which the dolerite intrusions occur ranges from 30 to 60 km in east–west direction, and is about 100 km in north–south ...

Tectono-Thermal Evolution of the Red Sea Rift

open access: yesFrontiers in Earth Science, 2021
The Oligocene-Recent Red Sea rift is one of the preeminent examples of lithospheric rupture in the recent geological past, forming the basis for many models of how continental breakup occurs and progresses to the formation of new oceanic crust ...
