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

The Mystery of Baselevel Controls in the Incision History of the Central Colorado Plateau
Erosion can remain active and changing in landscapes long after tectonic drivers have ceased, potentially due to local‐geologic controls, climate changes, or geodynamics. We present new fluvial incision‐rate histories and terrain analyses of the Colorado

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

Orthoptera insects (hereinafter – orthopterans) play a key role in grassland ecosystems and are often used as indicators of their condition. To conserve these insects and to model their habitat preferences, we need to know patterns of their distribution ...

Morphometric analysis of urban fluvial terraces using UAV LiDAR: A case study from the Santa Catarina River, Mexico [PDF]
This study analyzes the geomorphological evolution of fluvial terraces along the urban section of the Santa Catarina River (Nuevo León, México) by integrating high-resolution UAV-based LiDAR and photogrammetry.

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

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.

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 ...
