The dual role of fracturing and elevation on the development of the weathering profile in mafic landscapes of the Andean tropics

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Eighteen boreholes in Colombia's Tropical Andes reveal elevation‐controlled Critical Zone architecture. Four‐layer weathering profiles with thick saprolite (≤48 m) form at high elevations (>1,100 m) where dense fracturing enhances permeability. Low‐elevation boreholes lack saprolite despite high fracture density, demonstrating fracturing's dual role as

The Neolithic Site of Piano dei Cardoni in the Island of Ustica (Italy): Minero‐Petrographic and Chemical Characterization of the Ceramic Finds and Clayey Raw Materials

Geoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

Using Geophysical Observations of a Tracer Injection in a Riparian Aquifer to Explore How Bimodal Transport and Mixing Influences Nitrate Processing

Hydrological Processes, Volume 40, Issue 3, March 2026.
Our results embrace a simple conceptual model of preferential flow to illuminate the relationships among riparian groundwater nitrate concentration, flow dynamics, and substrate composition in stream corridors loaded with elevated nitrate from agricultural activities.

Landslide Character and Hydrological Thresholds for Slope Failure Initiation on Volcanic Scoria Slopes: Case Study From Mt Hobson/Ōhinerau, Auckland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Rainfall‐induced landslides involving on Auckland Volcanic Field scoria cones are highly unusual, compared with widespread landsliding in the surrounding Auckland clay‐rich residual soils. Indeed, while Auckland can suffer from thousands of rainfall‐induced shallow landslides from severe storms at subdecadal timescales, these are usually limited to ...
