Palaeomagnetic suitability of a new section with a potential lower boundary for the Quaternary on the left bank of the lower River Danube

open access: yesГеофизический журнал, 2022
A first palaeomagnetic study has been carried out on a new section with a potential lower boundary interval for the Quaternary, Dolynske 3. Recently, the Matuyama-Brunhes boundary (at 780 ka) was detected in the adjacent section of Dolynske 2.

Edge‐Driven Convection Melting Before the Emplacement of the Afar Mantle Plume Head Inferred From 40Ar/39Ar Dating

open access: yesGeophysical Research Letters, 2023
The Ethiopia‐Yemen flood basalts are spatially zoned with progressively lower TiO2 lavas from near the Afar depression toward the margins. The timing and rate of emplacement of low TiO2 (LT) lavas are poorly known compared with the ultra‐high TiO2 (HT2 ...

The early/middle Eocene transition at the Ésera valley (South Central Pyrenees): Implications in Shallow Benthic Zones (SBZ)

open access: yesGeologica Acta, 2022
An integrated study including magnetostratigraphy, larger benthic foraminifera and calcareous nannofossil biostratigraphy is presented herein. This work was performed in shallow marine siliciclastics rich in larger foraminifera, around the Ypresian ...

High-resolution magnetostratigraphic records of the pliocene sedimentary successions in Yengisar section, NW China, and its tectonic implications

open access: yesFrontiers in Earth Science, 2022
The Neogene strata upward-coarsening sandstone and conglomerate sequences at the periphery of the Northeastern Pamir record the intense uplift of the paleosurface of the building mountains.

Palaeomagnetism and magnetostratigraphy of the Permian and Triassic of Spitsbergen : a review of progress and challenges. [PDF]

open access: yes, 2008
Permian and Triassic sediments from Svalbard provide a testing ground for evaluating concepts about the polarity and configuration of the geomagnetic field during the Palaeozoic–Mesozoic transition.

Correlation of Eocene-Oligocene marine and continental records: orbital cyclicity, magnetostratigraphy and sequence stratigraphy of the Solent Group, Isle of Wight, UK [PDF]

open access: yes, 2006
The magnetostratigraphy, clay mineralogy, cyclostratigraphy and sequence stratigraphy of the estuarine and continental Solent Group (Isle of Wight, Hampshire Basin, UK), which is of Late Eocene–Early Oligocene age, were investigated.

Magnetostratigraphic Evidence From the Gengma Basin for the Fast Response of the Crustal Rotation of the Northern Part of the Shan‐Thai Block to the India‐Eurasia Convergence

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The Cenozoic tectonic evolution of the southeastern edge of the Tibetan Plateau is interpreted in terms of two alterative dynamic mechanisms: lateral extrusion of coherent lithospheric blocks and viscous lower crustal flow.

High-Resolution Late Devonian Magnetostratigraphy From the Canning Basin, Western Australia: A Re-Evaluation

open access: yesFrontiers in Earth Science, 2021
Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.

A Relative Paleointensity (RPI)-Calibrated Age Model for the Corinth Syn-rift Sequence at IODP Hole M0079A (Gulf of Corinth, Greece)

open access: yesFrontiers in Earth Science, 2022
The Corinth basin (Greece) is a young continental rift that recorded cyclic basin paleoenvironment variations (i.e., marine to lacustrine) caused by glacio-eustatic sea level fluctuations during its initial connection to the global oceans.
