Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Fluvial terrace formation in a mountainous area (2): influence of eustatism, tectonics and altitudinal distribution of watersheds based on an allostratigraphic study (Albania)

Comptes Rendus. Géoscience
Terraces are highly developed along the Albanian rivers and eleven levels of terraces are recognized in the area, nine occurring during the last glacial cycle (MIS 5d to end of MIS 2).

Erosive Response of Non-Glaciated Pyrenean Headwater Catchments to the Last Major Climate Transition and Establishing Interglacial Conditions

Quaternary, 2019
Non-glaciated mountain headwater catchments feature high-resolution geomorphic archives, which provide important insight into erosive processes and sediment dynamics in mountain ranges.

Surface ages of alluvial fans in the southern Central Andes recorded by ground‐ and space‐based hyperspectral reflectance

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Secondary weathering of alluvial‐fan surfaces records the relative, and even absolute, ages of deposited sediments up to 300 ka. Hyperspectral imagery quantifies evolving mineral‐weathering pathways to unlock high‐resolution mapping and dating of these sedimentary landscapes.

Tracing river dynamics: Multi‐temporal planform evolution and morphological change analyses in a meandering reach using high‐resolution satellite imagery and UAV data

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...

Fluvial terrace formation in mountainous areas: (1) Influence of climate changes during the last glacial cycle in Albania

Comptes Rendus. Géoscience
This work analyses terraces formation from the case of Albanian rivers. An allostratigraphy study of the fluvial terraces is combined with new numerical dating.

Slope and sediment size in the development of pebble and cobble beaches with low permeability

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
We studied beaches composed of coarse‐grained beaches. In spite that the occurrence of an impermeable layer at a low depth that reduces its permeability, the correlation between the beach slope and the sediment size corresponds to what was expected, and the underlying and cohesive sediment reached the same slope of the beach.

Variability in the Vineyard: A Multi‐Method Approach in Determining Grapevine Evapotranspiration Across Different Varietal Blocks

Hydrological Processes, Volume 40, Issue 8, August 2026.
To address the variability of evapotranspiration (ET) in vineyards, a multi‐method approach combining the use of in‐field atmometer ET gauges and the FAO‐56 dual crop coefficient procedure was employed. Reference ET and crop ET adjusted for water stress resulted in consistencies between white varietals, while Pinot Noir exhibited reductions in ...
