Ostracode-based aminostratigraphy and aminochronology of a tufa system in central Spain [PDF]

open access: yes, 2005
In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons ...

Geomorphological analysis using small unmanned aerial vehicles and submeter GNSS (Gara Soultana butte, High Plateaus Basin, Eastern Morocco)

open access: yesJournal of Maps, 2020
The High Plateaus Basin is an important region to understand landscape evolution and human occupation in North Africa during the Quaternary. We focused on the Gara Soultana area, applying Unmanned Aerial Vehicles, photogrammetry and a submeter Global ...

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

open access: yesFrontiers 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.

Geomorphic signal of active faulting at the northern edge of Lut Block. Insights on the kinematic scenario of Central Iran [PDF]

open access: yes, 2016
Recent works documented Neogene to Quaternary dextral strike-slip tectonics along the Kuh-e-Sarhangi and Kuh-e-Faghan intraplate strike-slip faults at the northern edge of the Lut Block of Central Iran, previously thought to be dominated by sinistral ...

Kinematic analysis of the Pakuashan fault tip fold, west central Taiwan: Shortening rate and age of folding inception [PDF]

open access: yes, 2007
The Pakuashan anticline is an active fault tip fold that constitutes the frontal most zone of deformation along the western piedmont of the Taiwan Range.

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]

open access: yes, 2019
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.

SEDIMENTS AND AGE OF TERRACES AND FLOODPLAINS OF THE EZOUSAS RIVER IN SW CYPRUS [PDF]

open access: yesActa Geobalcanica, 2021
Since 2014 Jan Kochanowski University in Kielce participate in the research in Paphos region in SW Cyprus. The aim of geomorphologic study was the age and sediments of terraces and floodplains in Ezousas river valley.

Modeling the shortening history of a fault tip fold using structural and geomorphic records of deformation [PDF]

open access: yes, 2007
We present a methodology to derive the growth history of a fault tip fold above a basal detachment. Our approach is based on modeling the stratigraphic and geomorphic records of deformation, as well as the finite structure of the fold constrained from ...

Pleistocene terraced fluvial succession, northern slope of Torino Hill [PDF]

open access: yesQuaternary International, 2007
Abstract A Pleistocene terraced fluvial succession is found on the northern slope of the Torino Hill. This succession consists of many relics of flat surfaces, separated by scarps, often associated with sandy and silty deposits, perched from 30 to 400 m on the Po Plain. Terraced surfaces at high levels are more deformed, dissected and mostly deprived

Sporepolinic morphology of fluvial terrace sediments in the Western Amazon [PDF]

open access: yesActa Botanica Brasilica, 2020
ABSTRACT Morphological descriptions were made for pollen grains and spores extracted from samples from three sedimentary sections - Chandless 1, Purus 10 and Purus 30 - from fluvial terraces on the Chandless and Purus rivers, Acre State, Brazil. Level CH1-12 at Chandless 1 was C14-dated to 4861 - 5050 cal yr BP, P10-3 of Purus 10 was dated through the ...
