High-precision U–Pb ages in the early Tithonian to early Berriasian and implications for the numerical age of the Jurassic–Cretaceous boundary [PDF]

Solid Earth, 2019
The numerical age of the Jurassic–Cretaceous boundary has been controversial and difficult to determine. In this study, we present high-precision U–Pb geochronological data around the Jurassic–Cretaceous boundary in two distinct sections from different ...

Stimulated Volume Determination of a Horizontal Well in a Shale Oil Reservoir in the Vaca Muerta Formation and Its Interaction With Existing Fracture Networks

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Hydraulic fracturing is a stimulation technique that plays a critical role to provide transport path networks in unconventional shale reservoirs, yet the quantitative characterization of fracture propagation, its interaction with natural discontinuities, and the resulting stimulated volume remain challenging in heterogeneous formations such as the Vaca

Changes in Motion of the Nazca/Farallon Plate Over the Last 34 Million Years: Implications for Flat‐Slab Subduction and the Propagation of Plate Kinematic Changes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract A high‐resolution sequence of finite‐rotation solutions spanning the past 34 Myr for the Nazca plate relative to the Pacific, Antarctic, and South American plates shows a pattern of 1–5‐Myr‐long intervals of nearly constant plate motion mostly separated by decelerations or accelerations lasting no longer than a few hundred thousand years ...

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

Antipode, Volume 57, Issue 6, Page 2213-2240, November 2025.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Modeling Overpressure Development and the Mechanical Behavior of Sediments in a Complex, Tectonically Active Setting: East Coast Basin, New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The East Coast Basin (ECB) is a complex, active convergent margin located on the North Island of New Zealand, where variable but commonly very high overpressures occur in Cretaceous to Pleistocene stratigraphy. Using a consistent set of sediment physical properties and a single value for tectonic compression, a multi‐1D hydro‐mechanical ...
