Marked Ericales diversity in late Oligocene–Early Miocene palynofloras from northern Thailand suggests stratified mountain forests

open access: yesJournal of Systematics and Evolution, EarlyView.
A total of 24 different ericalean pollen types were recovered from the Ban Pa Kha Subbasin, Li Basin, northern Thailand. Based on the ecological preferences of their modern analogs, the assemblage of dispersed ericalean pollen likely derives from more than one vegetation type and possibly from different vertical zones of mountainous areas, as indicated

Intermittent Brittle and Ductile Deformation as Recorded by Dating of Ultramylonites and Pseudotachylytes in Extending Continental Crust (Ivrea‐Verbano Zone, Italy)

open access: yesTerra Nova, EarlyView.
ABSTRACT Mylonites and pseudotachylytes play a crucial role in defining the rheology of extending continental crust. In this context, determining the age of brittle‐ductile deformation is fundamental to understanding the rifting evolution stages. Here, we investigate the Premosello Shear Zone, an extensional structure of the Ivrea‐Verbano lower crust ...

Magnetostratigraphy and Source Characterisation Across the Early Miocene Unconformity, Northern Rocky Mountains, USA

open access: yesTerra Nova, EarlyView.
ABSTRACT The early Miocene unconformity (EMU) formed during a transition in the tectonic regime of western North America that coincided with faunal diversification. The Railroad Canyon section in the northern Rocky Mountains provides a complete geologic record around this event. Our new magnetostratigraphic study in combination with published U‐Pb ages

Long‐Lasting Plutonism During Orogenic Cycles: Incremental Emplacement of the Variscan Bassiès Pluton (Central Pyrenees, France)

open access: yesTerra Nova, EarlyView.
ABSTRACT Laser ablation U–Pb single zircon geochronology was applied to four peraluminous granite and granodiorite samples from the Bassiès pluton in the Central Pyrenees (France) yielding a wide range of concordant ages from early Carboniferous (Tournaisian, 351 Ma) to early Permian (Artinskian, 285 Ma).

Influence of Fluids and Geological Setting on Source Parameters of the 2010–2014 Pollino (Italy) Seismic Swarm

open access: yesTerra Nova, EarlyView.
ABSTRACT We analyse variations in Brune stress drop (Δσ), apparent stress (τa) and Savage–Wood radiation efficiency (ηsw = τa/Δσ) during the 2010–2014 Pollino seismic swarm (Southern Apennines, Italy). This prolonged sequence included multiple swarms, with a Mw 5.2 event in October 2012, preceded by a Mw 4.3 event in May 2012, followed by aseismic slip.

Was the Formation of the North Anatolian Fault Influenced by the Aegean Extension?

open access: yesTerra Nova, EarlyView.
ABSTRACT The North Anatolian Fault (NAF), one of the most prominent plate boundary continental fault systems on Earth, facilitates the westward movement of the Anatolian microplate into the Aegean region. The temporal and spatial evolution of the NAF is important for understanding the mechanism of escape tectonics during plate interaction in active ...
