Rift systems of the Russian Eastern Arctic shelf and Arctic deep water basins: link between geological history and geodynamics

open access: yesГеодинамика и тектонофизика, 2017
In our study, we have developed a new tectonic scheme of the Arctic Ocean, which is based mainly on seismic profiles obtained in the Arctic-2011, Arctic-2012 and Arctic-2014 Projects implemented in Russia.

Testing of multidimensional tectonomagmatic discrimination diagrams on fresh and altered rocks

open access: yesGeologica Carpathica, 2016
We evaluated 55 multidimensional diagrams proposed during 2004-2013 for the tectonic discrimination of ultrabasic, basic, intermediate, and acid magmas.

Complex rift geometries resulting from inheritance of pre-existing structures: Insights and regional implications from the Barmer Basin rift [PDF]

open access: yes, 2014
Structural studies of the Barmer Basin in Rajasthan, northwest India, demonstrate the important effect that pre-existing faults can have on the geometries of evolving fault systems at both the outcrop and basin-scale.

Anatomy and Sequence Architecture of the early Post-Rift in the Neuquén Basin (Argentina): A Response to Physiography and Relative Sea-level Changes [PDF]

open access: yes, 2013
A detailed architectural and sequence stratigraphic analysis was carried out in the early-post-rift succession of central Neuque´n Basin (Middle Jurassic Cuyo Group), integrating outcrop and subsurface information from a 3,000 km2 area.

The UNESCO World Heritage Site of the Chaîne des Puys–Limagne Fault Tectonic Arena (Auvergne, France)

open access: yesGeosciences, 2023
The tectono-volcanic ensemble of the Chaîne des Puys and the Limagne fault, which is part of the West European rift, was inscribed on the UNESCO World Heritage list in 2018 as the Chaîne des Puys–Limagne fault tectonic arena.

Rifts in Spreading Wax Layers

open access: yes, 1995
We report experimental results on the rift formation between two freezing wax plates. The plates were pulled apart with constant velocity, while floating on the melt, in a way akin to the tectonic plates of the earth's crust.

Stratigraphy of the Hawai'i Scientific Drilling Project core (HSDP2): Anatomy of a Hawaiian shield volcano [PDF]

open access: yes, 2007
The Hawai'i Scientific Drilling Project (HSDP2) successfully drilled ∼3.1 km into the island of Hawai'i. Drilling started on Mauna Loa volcano, drilling 247 m of subaerial lavas before encountering 832 m of subaerial Mauna Kea lavas, followed by 2019 m ...
