Exhumation and uplift of the Sierras Pampeanas: preliminary implications from K–Ar fault gouge dating and low-T thermochronology in the Sierra de Comechingones (Argentina)
Löbens, Stefan; Bense, Frithjof;
; ; Costa, Carlos; Layer, Paul; Siegesmund, Siegfried (International Journal of Earth Sciences, 2011)
The Sierras Pampeanas in central and north-western Argentina constitute a distinct morphotectonic feature between 27°S and 33°S. The last stage of uplift and deformation in this area are interpreted to be closely related ... -

Die Exkursion stellt repräsentative Aufschlüsse triassischer und jurassischer Sedimente aus der direkten Umgebung von Göttingen vor. Dabei werden deren stratigraphische Stellung, Ablagerungsmilieus und Fossilgemeinschaften ... -
Exoten in der Großsäuger-Fauna des letzten Interglazials von Mitteleuropa
(E&G – Quaternary Science Journal; Vol.41, No. 1)Auf das Vorkommen von Hippopotamus amphibius, Bubalus murrensis, Cervus dama und einem kleinen Nashorn (Dicerorhinus cf. megarhinus) in der letztinterglazialen Fauna der nördlichen Oberrheinebene wird hingewiesen und die ... -
Expansion and Shrinking of the Martian Topside Ionosphere
; ; ; Woch, J.; McFadden, J.; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2019)
The observations made by the Mars Atmosphere and Volatile EvolutioN spacecraft in the topside (≥200 km) ionosphere of Mars show that this region is very responsive to the variations of the external (solar extreme ultraviolet ... -
Experiencing climate change: revisiting the role of local weather in affecting climate change awareness and related policy preferences
; (Climatic Change, 2021-08-06)
Over the last few years, climate change has risen to the top of the agenda in many Western democracies, backed by a growing share of voters supporting climate protection policies. To understand how and why these changes ... -
Experimental deformation of jadeite

Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions: Mechanical Properties and the Influence of Rock Fabric
; ; ; ; ; (Rock Mechanics and Rock Engineering, 2021-05-11)
The mechanical behavior of the sandy facies of Opalinus Clay (OPA) was investigated in 42 triaxial tests performed on dry samples at unconsolidated, undrained conditions at confining pressures (pc) of 50–100 MPa, temperatures ... -
Experimental Evaluation of Airlift Performance for Vertical Pumping of Water in Underground Mines
; ; (Mine Water and the Environment, 2021-08-14)
This paper presents experimental studies on the optimization of air–water flow in an airlift pump. Airlift pumps use compressed gas to verticall transport liquids and slurries. Due to the lack of theoretical equations for ... -
Experimental Evaluation of Fluid Connectivity in Two‐Phase Flow in Porous Media During Drainage
; ; ; (Water Resources Research, 2022-11-04)
This study aims to experimentally investigate the possibility of combining two extended continuum theories for two‐phase flow. One of these theories considers interfacial area as a separate state variable, and the other ... -
