Stratigraphy and sedimentology of a Lower-Middle Miocene section in the Miranda-Trebiño basin, NE Iberia

Geogaceta
This work is focused on a Lower–Middle Miocene section exposed on the northern flank of Miranda Trebiño piggy-back basin (Cucho section). The sedimentological and stratigraphic study of the section, composed of up to 160 m of terrigenous, mixed (marls),

Spatiotemporal changes in soil chemical properties when cover crops are integrated into raised, stale seedbed corn production systems

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Commercial row crop production in the midsouthern United States is characterized by extensive application of inorganic soil inputs and management practices that contribute to degraded soil health. This study was conducted to determine if cover crops affect spatial or temporal changes in soil chemical properties in a raised, stale seedbed ...

Application of multispectral radar and LANDSAT imagery to geologic mapping in death valley [PDF]

Side-Looking Airborne Radar (SLAR) images, acquired by JPL and Strategic Air Command Systems, and visible and near-infrared LANDSAT imagery were applied to studies of the Quaternary alluvial and evaporite deposits in Death Valley, California. Unprocessed

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Supercritical‐flow structures in a Cretaceous submarine channel–lobe transition zone, Point Loma Formation, California

The Depositional Record, Volume 12, Issue 3, June 2026.
We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...

Monitoring sediment transfer processes on the desert margin [PDF]

LANDSAT Thematic Mapper and Multispectral Scanner data have been used to construct change detection images for three playas in south-central Tunisia. Change detection images have been used to analyze changes in surface reflectance and absorption between ...

Climate Controls on Carbon Dioxide Fluxes in a High‐Elevation Grassland

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Climate change is significantly influencing high‐elevation grasslands, possibly unbalancing CO2 exchanges and the sink‐source dynamics. Cumulated heat available for plant growth and vegetation cover were identified as the main controllers of phenological development and, via direct or mediated effects, of CO2 fluxes (ER and GPP).

MIDDLE MIOCENE DEPOSITIONAL MODEL IN THE DRAVA DEPRESSION DESCRIBED BY GEOSTATISTICAL POROSITY AND THICKNESS MAPS (CASE STUDY: STARI GRADAC-BARCS NYUGAT FIELD)

Rudarsko-geološko-naftni Zbornik, 2006
Neogene depositional environments in the Drava depression can be classified in two groups. One group is of local alluvial fans, which were active during the period of Middle Miocene (Badenian) extension through the entire Pannonian Basin.

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.
