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.

Kuroko Deposits of NE Japan: The Product of High‐Temperature, Shallow Felsic Volcanism in a Deepening Continental Rift

open access: yesTerra Nova, EarlyView.
ABSTRACT The Hokuroku district of NE Japan hosts the type locality for Kuroko volcanic‐hosted massive sulphide (VHMS) deposits, which are the product of seafloor hydrothermal venting in a continental rift during the opening of the Sea of Japan in the Miocene.

Cooling and Exhumation History of the Paris Basin Southeastern Margin Revealed by Δ47 /U–Pb Carbonate Thermochronology

open access: yesTerra Nova, EarlyView.
ABSTRACT This study applies Δ₄₇/U–Pb thermochronology to the Middle Jurassic carbonates exposed in the southeastern margin of the Paris Basin. By integrating clumped isotope analyses and U–Pb dating of diagenetic carbonates, we reconstruct the thermal and exhumation history of the sedimentary succession.
