Spatial and Temporal Evolution of Graben Formation During Rift Linkage Using Quantitative Geomorphology: Insights From Central Afar

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Quantifying fault slip rates and resolving rift segment linkage mechanisms is important for understanding the evolution of magma‐rich rift systems and the broader processes of continental break‐up. In tectonically and volcanically active rifts, such as Afar, there is commonly a lack of quantitative, observational constraints on long‐term fault

A New View of Long-Term Geomagnetic Field Secular Variation

Frontiers in Earth Science, 2018
This study carries out a statistical analysis of high-resolution PSV records for the last ~70 ka from three different regions of the Earth. We consider directional and intensity variability in each region on time scales of 103-105 years in order to ...

PALEOMAGNETISM OF SILURIAN AND DEVONIAN VOLCANICS FROM THE CHINGIZ ISLAND ARC, KAZAKHSTAN, AND ITS BEARING ON TECTONIC EVOLUTION OF THE URAL-MONGOL BELT

Геодинамика и тектонофизика, 2015
The tectonic and paleogeographic evolution of the Ural-Mongol belt between the cratons of Baltica, Siberia, and Tarim is the key to the formation of the Eurasian supercontinent during Paleozoic time, but the views on this complicated process remain very ...

Paleomagnetism‐Based Chronology of Holocene Lava Flows at Mt Ruapehu, Aotearoa New Zealand

Geochemistry, Geophysics, Geosystems
Dating young lava flows is essential for understanding volcano's eruption frequency, yet challenging due to methodological limitations of commonly used dating techniques.

Bio-, Magneto- and event-stratigraphy across the K-T boundary [PDF]

Determining the time and the time structure of rare events in geology can be accomplished by applying three different and independent stratigraphic methods: Biostratigraphy, magneto-stratigraphy and event-stratigraphy.

Post-Eocene rotations in the Western Alpine realm: a review from sixty eight years of paleomagnetic investigations

BSGF - Earth Sciences Bulletin
A synthesis of more than 55 paleomagnetic studies yielding Tertiary primary or secondary magnetizations is used to evidence the rotations around a vertical axis since 40 Ma in the Western Alps and surrounding areas. In both external and internal zones of
