Climate changes and the formation of fluvial terraces in central Amazonia inferred from landscape evolution modeling [PDF]

Earth Surface Dynamics, 2022
Climate changes have been considered an essential factor controlling the shaping of the recent alluvial landscapes in central Amazonia, with implications for explaining the biogeographic patterns in the region.

Effects of Erosion and Deposition on Constraining Vertical Slip Rates of Thrust Faults: A Case Study of the Minle–Damaying Fault in the North Qilian Shan, NE Tibetan Plateau

Frontiers in Earth Science, 2021
The height of a thrust-fault scarp on a fluvial terrace would be modified due to erosion and deposition, and these surface processes can also influence the dating of terraces.

Climate changes and the formation of fluvial terraces in central Amazonia [PDF]

, 2021
Abstract. Climate changes have been considered as an essential factor controlling the shaping of the recent alluvial landscapes in central Amazonia, with implications for explaining the biogeographic patterns in the region. This landscape is characterized by wide floodplains and various terrace levels at different elevations.

Diverse Responses of Alluvial Rivers to Periodic Environmental Change

Geophysical Research Letters, 2023
Alluvial rivers aggrade, incise, and adjust their sediment‐transport rates in response to changing sediment and water supply. Fluvial landforms, such as river terraces, and downstream stratigraphic archives may therefore record information about past ...

Late Quaternary Drainage Rearrangement Prevents the Vegetation Development in the La Tatacoa Intermontane Basin of the Colombian Andes

Frontiers in Earth Science, 2022
The Tatacoa Desert (TD) is a Cenozoic basin between the Central and Eastern Cordilleras in the southern Colombian Andes. Its sparse vegetation and Badlands morphology resemble a semi-arid environment, despite receiving ∼1,300 mm of mean annual ...

Fluvial terraces of the northwest Iberian lower Miño River

Journal of Maps, 2013
A new fluvial terrace map with a tectonic framework for the northwest Iberian lower Miño River is presented. It is the first integrated map to cover the entire lower, 67-km reach of the Miño River, and to cover both the Spanish and Portuguese side of the river.

Substratum sedimentology and topography of two riparian peat bogs in the Bieszczady Mountains (Carpathians) [PDF]

Mires and Peat, 2020
The valley of the upper course of the San River in the Bieszczady Wysokie mountain range is, after the Orawa-Nowy Targ Basin, the area with the largest number of peat bogs in the Polish Carpathians.

GEOCHRONOLOGY AND HYDRODYNAMIC ENERGY CONDITIONS IN SURFACE COVERINGS OF LOW HOLOCENE FLUVIAL, FLUVIAL-MARINE, AND MARINE TERRACES: CLIMATIC PULSATIONS TO THE SOUTH OF THE ARANGUAGUÁ RIVER BASIN (SC)

Revista Brasileira de Geomorfologia, 2018
This research aims to perform the geochronology of surface coverings in low Holocene marine, fluvial-marine, and fluvial terraces, associating the genesis of paleo-forms with the occurrence of Holocene climatic pulsations, the consequential switches ...

Luminescence Ages of Feldspar Contaminated Quartz from Fluvial Terrace Sediments [PDF]

Geochronometria, 2008
This study focuses on obtaining luminescence ages in feldspar contaminated quartz from well-developed fluvial terraces of the Yesilirmak (Iris) river located inside the eastern North Anatolian Fault Shear Zone (NAFZ). We applied a technique based on conventional single-aliquot regenerative-dose (SAR) protocol, modified with an IR pre-treatment to ...
