Orogen-scale transpression accounts for GPS velocities and kinematic partitioning in the Southern Andes
(
- Communications Earth & Environment
, 2021-08-19)
The Southern Andes are regarded as a typical subduction orogen formed by oblique plate convergence. However, there is considerable uncertainty as to how deformation is kinematically partitioned in the upper plate. Here we ...
Comparing different machine‐learning techniques to date Nile Delta sediments based on portable X‐ray fluorescence data
(
- Geoarchaeology
, 2022-11-01)
Geomorphology generally aims to describe and investigate the processes that lead to the formation of landscapes, while geochronology is needed to detect their timing and duration. Due to restrictions on exporting geological ...

Geographic object‐based image analysis (GEOBIA) of the distribution and characteristics of aeolian sand dunes in Arctic Sweden
(
- Permafrost and Periglacial Processes
, 2022-10-09)
Current climate change in the Arctic is unprecedented in the instrumental record, with profound consequences for the environment and landscape. In Arctic Sweden, aeolian sand dunes have been impacted by climatic changes ...
Can Offshore Meteoric Groundwater Generate Mechanical Instabilities in Passive Continental Margins?
(
- Journal of Geophysical Research: Earth Surface
, 2023-02-26)
Offshore meteoric groundwater (OMG) has long been hypothesized to be a driver of seafloor geomorphic processes in continental margins worldwide. Testing this hypothesis has been challenging because of our limited understanding ...
The Langeland Fault System unravelled: Quaternary fault reactivation along an elevated basement block between the North German and Norwegian–Danish basins
(

, 2023-02-08)
<p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en">The reactivation of faults and possible impact on barrier integrity marks a critical aspect for investigations on subsurface usage capabilities. Glacial ...
Deriving Debris‐Flow Dynamics From Real‐Time Impact‐Force Measurements
(
- Journal of Geophysical Research: Earth Surface
, 2023-03-21)
Understanding the impact forces exerted by debris flows is limited by a lack of direct field measurements and validated numerical models. In this study, we use real‐time impact‐force measurements and field observations of ...
Rinikerfeld Palaeolake (Northern Switzerland) – a sedimentary archive of landscape and climate change during the penultimate glacial cycle
(
- Journal of Quaternary Science
, 2022-08-16)
While timing and ice extent of the last glacial maximum are generally well known, the courses of earlier glaciations have remained poorly constrained, with one of the main reasons being the scarcity of sedimentary archives. ...
A Comparison of Plasticity Regularization Approaches for Geodynamic Modeling

Shaping the Huara Intrusive Complex in the Hyperarid Atacama Desert—Erosional Near‐Stasis Contrasting High Topographic Gradients
(
- Journal of Geophysical Research: Earth Surface
, 2023-03-10)
The Atacama Desert is one of the driest and oldest deserts on Earth, with extremely low precipitation rates (<2 mm/yr). Mostly abiotic hyperarid environmental conditions prevail, and surface processes act at extremely low ...
