Regional‐Scale Landscape Response to an Extreme Precipitation Event From Repeat Lidar and Object‐Based Image Analysis

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract Extreme precipitation events may cause flooding, slope failure, erosion, deposition, and damage to infrastructure over a regional scale, but the impacts of these events are often difficult to fully characterize. Regional‐scale landscape change occurred during an extreme rain event in June 2012 in northeastern Minnesota.

An origin of ultraslow spreading ridges for the Yarlung-Tsangpo ophiolites

Fundamental Research, 2022
As relics of ancient ocean lithosphere, ophiolites are the most important petrological evidence for marking the sutures and also play a key role in reconstructing plate configuration.

Estratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina [PDF]

, 2015
Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including the Austral (foreland) Basin (

The Baia–Fondi di Baia eruption at Campi Flegrei: stratigraphy and dynamics of a multi-stage caldera reactivation event

Bulletin of Volcanology, 2017
The Baia–Fondi di Baia eruption is one of the sporadic events that have occurred in the western sector of the Campi Flegrei caldera. It dates back to 9525–9696 bp and opened Epoch 2 of the caldera activity after a 1000-year-long period of quiescence. Although relatively small in terms of erupted volume with respect to most of the events of the past 15 ...

Mixed clastic‐carbonate lake margin systems: An example from the Triassic of East Greenland

The Depositional Record, EarlyView.
This study examines a rare example of a mixed clastic‐carbonate shore zone from the Late Triassic of East Greenland. Two facies models are proposed. The interaction of sediment supply and production are shown to be key factors in governing facies development and these are in turn predominantly controlled by lake‐level dynamics and lake margin ...

Testing Predictions for Migration of Meandering Rivers: Fit for a Curvature‐Based Model Depends on Streamwise Location and Timescale

Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022
Abstract Many meandering rivers migrate, at rates that vary both along‐stream and inversely with the observation interval. Many numerical models have been developed to predict this migration; their success is usually evaluated statistically or by qualitative comparison to observations in map view.

Sedimentology and reservoir characterisation of Lower Jurassic clastic sedimentary rocks, Salt and Trans Indus Ranges, Pakistan: Evidence from petrography, scanning electron microscopy and petrophysics

The Depositional Record, EarlyView.
In this study, sandstones of the Lower Jurassic Datta Formation (DF‐LJ) in the Salt and Trans‐Indus Ranges are investigated regarding composition, diagenesis, provenance and reservoir properties using petrography, scanning electron microscopy (SEM) and petrophysical analysis.

Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls

Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022
Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.
