Cone penetration tests in dry and saturated Ticino sand
; ; ; ; ; (Bulletin of Engineering Geology and the Environment, 2021-03-11)
It is commonly assumed that dry and saturated sands exhibit similar cone resistance–relative density relationships. Some studies pointed out that partial saturation and calcareous sands with considerable fines content are ... -
Constraining Andean Propagation of Exhumation at the Limit of the Eastern Cordillera, NW Argentina, Using Low‐Temperature Thermochronology in a Structural Context
; ; ; ; (Tectonics, 2022-08-16)
Within the Central Andes of NW Argentina, the spatiotemporal distribution and style of deformation is strongly influenced by pre‐Cenozoic heterogeneities, mostly related to the Salta rift extension in the Cretaceous. At ... -
Constraining the Variability of the Atlantic Meridional Overturning Circulation During the Holocene
; ; ; ; ; ; ; ; ; ; (Geophysical Research Letters, 2019)
There is a converging body of evidence supporting a measurable slowdown of the Atlantic Meridional Overturning Circulation (AMOC) as climate warms and Northern Hemisphere ice sheets inexorably shrink. Within this context, ... -
Contemporaneous assembly of Western Gondwana and final Rodinia break-up: Implications for the supercontinent cycle
Oriolo, Sebastián; Oyhantçabal, Pedro;; Siegesmund, Siegfried (Geoscience Frontiers, 2017)
Geological, geochronological and isotopic data are integrated in order to present a revised model for the Neoproterozoic evolution of Western Gondwana. Although the classical geodynamic scenario assumed for the period ... -
Continuous assessment of landslides by measuring their basal temperature
; (Landslides, 2021-09-18)
In this study, we suggest a temperature-based assessment and mitigation approach for deep-seated landslides that allows to forecast the behavior of the slide and assess its stability. The suggested approach is validated ... -
Continuum-mechanical, Anisotropic Flow model for polar ice masses, based on an anisotropic Flow Enhancement factor
(Continuum Mechanics and ThermodynamicsContinuum Mechanics and Thermodynamics, 2009)A complete theoretical presentation of the Continuum-mechanical, Anisotropic Flow model, based on an anisotropic Flow Enhancement factor (CAFFE model) is given. The CAFFE model is an application of the theory of mixtures ... -
Controlling factors and environmental significance of organomicrite production and buildup development

Controls of the Foreland Deformation Pattern in the Orogen‐Foreland Shortening System: Constraints From High‐Resolution Geodynamic Models
; ; ; (Tectonics, 2022-02-17)
Controls on the deformation pattern (shortening mode and tectonic style) of orogenic forelands during lithospheric shortening remain poorly understood. Here, we use high‐resolution 2D thermomechanical models to demonstrate ... -
Controls on Asymmetric Rift Dynamics: Numerical Modeling of Strain Localization and Fault Evolution in the Kenya Rift
; ; ; ; ; (Tectonics, 2021-05-10)
Complex, time‐dependent, and asymmetric rift geometries are observed throughout the East African Rift System (EARS) and are well documented, for instance, in the Kenya Rift. To unravel asymmetric rifting processes in this ... -
Controls on the lateral channel-migration rate of braided channel systems in coarse non-cohesive sediment
; ; ; ; ; (Earth Surface Processes and Landforms, 2019)
Lateral movements of alluvial river channels control the extent and reworking rates of alluvial fans, floodplains, deltas, and alluvial sections of bedrock rivers. These lateral movements can occur by gradual channel ... -
Created by the Monte Peron rock avalanche: Lago di Vedana (Dolomites, Italy) and its sediment record of landscape evolution after a mass wasting event
; ; (Landslides, 2021-11-27)
The timing of the Monte Peron Landslide is revised to 2890 cal. BP based on a radiocarbon-dated sediment stratigraphy of Lago di Vedana. This age fosters the importance of hydroclimatic triggers in the light of accelerating ... -
Cretaceous Evolution of the Central Asian Proto-Paratethys Sea: Tectonic, Eustatic, and Climatic Controls
; ; ; ; ; ; ; ; ; ; ; (Tectonics, 2020)
The timing and mechanisms of the Cretaceous sea incursions into Central Asia are still poorly constrained. We provide a new chronostratigraphic framework based on biostratigraphy and magnetostratigraphy together with ... -
Crustal architecture of a metallogenic belt and ophiolite belt: implications for mineral genesis and emplacement from 3-D electrical resistivity models (Bayankhongor area, Mongolia)
; ; ; (Earth, Planets and Space, 2021-04-01)
Crustal architecture strongly influences the development and emplacement of mineral zones. In this study, we image the crustal structure beneath a metallogenic belt and its surroundings in the Bayankhongor area of central ... -
Crustal Structure of the Niuafo'ou Microplate and Fonualei Rift and Spreading Center in the Northeastern Lau Basin, Southwestern Pacific
; ; ; ; ; ; Hannington, M. D.; ; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2020-06-11)
The northeastern Lau Basin is one of the fastest opening and magmatically most active back‐arc regions on Earth. Although the current pattern of plate boundaries and motions in this complex mosaic of microplates is reasonably ... -
Crustal variability along the rifted/sheared East African margin: a review
; (Geo-Marine Letters, 2021-04-08)
The East African margin between the Somali Basin in the north and the Natal Basin in the south formed as a result of the Jurassic/Cretaceous dispersal of Gondwana. While the initial movements between East and West Gondwana ... -
Crustal‐Scale Sheath Folding at HP Conditions in an Exhumed Alpine Subduction Zone (Tauern Window, Eastern Alps)
; ; ; Pestal, Gerhard; Pleuger, Jan (Tectonics, 2020-02-21)
We investigate a well‐preserved paleo subduction channel that preserves a coherent part of the European continental margin exposed in the central Tauern Window (Eastern Alps), with the aim of testing models of sheath fold ... -
Cryosphere hazards in Ladakh: the 2014 Gya glacial lake outburst flood and its implications for risk assessment
; ; ; (Natural Hazards, 2020-09-05)
This article attempts to reconstruct the causes and consequences of the 2014 glacial lake outburst flood (GLOF) event in Gya, Ladakh. We analyse the evolution of the Gya glacial lake using a high temporal and high spatial ... -
Current and future state of groundwater salinization of the northern Elbe-Weser region
; ; ; ; (Grundwasser, 2021-11-11)
Salinization of the upper aquifer of the northern Elbe-Weser region almost extends to the surface. Chloride content exceeds 250 mg/l and the groundwater is therefore, according to the German Drinking Water Ordinance, not ... -
