Driving mechanisms of Holocene lagoon development and barrier accretion in Northern Elis, Peloponnese, inferred from the sedimentary record of the Kotychi Lagoon
(E&G – Quaternary Science Journal; Vol.63)As part of the lagoon barrier accretions plain characterizing the NW coast of the Peloponnese, the Kotychi Lagoon is believed to have formed in the prograding delta of the Palaeo-Peneus River over 7000 years ago. ... -
Gas Geochemistry and Isotopic Signatures in the deep Thermal waters in Jordan
(Freiberg Online Geosciences; Vol. 16.2006)In der vorliegenden Arbeit wurden die Hydrochemie und die Isotopensignale von Thermalwässern entlang der östlichen Seite des Dead Sea Transform (DST) in Jordanien untersucht. Die Hauptziele dieser Untersuchungen waren: ... -
Implications of Reactions Between SO2 and Basaltic Glasses for the Mineralogy of Planetary Crusts
(Journal of Geophysical Research: Planets, 2019)Basalts are ubiquitous in volcanic systems on several planetary bodies, including the Earth, Mars, Venus, and Jupiter's moon Io, and are commonly associated with sulfur dioxide (SO2) degassing. We present the results of ... -
Multiproxy-Untersuchungen zur Paläoökologie und -hydrologie eines spätglazial- bis frühholozänen Flachsees im nordostdeutschen Küstengebiet (Glowe-Paläosee/Insel Rügen)
(E&G – Quaternary Science Journal; Vol.65)The paper presents results of multiproxy-investigations of a 3 m long sediment section from the Glowe Palaeolake, covering the period Pre-Bølling to the middle of the Preboreal. The Lateglacial and early Holocene landscape ... -
New results concerning the pedo‐ and chronostratigraphy of the loess–palaeosol sequence Attenfeld (Bavaria, Germany) derived from a multi‐methodological approach
; Klasen, Nicole; ; (Journal of Quaternary Science, 2021-03-18)
Loess–palaeosol sequences (LPS) represent important records of palaeoenvironmental dynamics throughout the Quaternary. During the Pleistocene's dry and cold phases, the Danube's riverbed was one of the major sources for ... -
Offshore Freshened Groundwater in Continental Margins

First reported in the 1960s, offshore freshened groundwater (OFG) has now been documented in most continental margins around the world. In this review we compile a database documenting OFG occurrences and analyze it to ... -
Quartärgeologisch-tephrostratigraphische Neuaufnahme und Interpretation des Pleistozänprofils Kärlich
(E&G – Quaternary Science Journal; Vol.39, No. 1)Die quartäre Sedimentfolge der Kärlicher Tongrube ist ein Schlüsselprofil für das Pleistozän Mitteleuropas: (a) Rhein- und Mosel-Terrassenablagerungen belegen die junge tektonische Hebung des paläozoischen Rheinischen ... -

Stratigraphy, geochemistry and palaeomagnetism of late quaternary bedrock and paleosols, Karisoke Area, Virunga Mountains, Northwestern Rwanda
(E&G – Quaternary Science Journal; Vol.42, No. 1)Ein rezenter Boden und zwei begrabene Paläoböden, Einheiten II-III-IV (oberer) und IV (unterer)-V, liefern wichtige Informationen über Paläoklima und Abflußverhältnisse in den Virunga-Bergen von trockeneren zu feuchteren ... -
Testing the preservation potential of early diagenetic dolomites as geochemical archives
; Igbokwe, Onyedika A.; Walter, Benjamin; ; Riechelmann, Sylvia; Richter, Detlev K.; ; ; Buhl, Dieter; Neuser, Rolf D.; Bertotti, Giovanni; Immenhauser, Adrian (Sedimentology, 2019-10-25)
Early marine diagenetic dolomite is a rather thermodynamically‐stable carbonate phase and has potential to act as an archive of marine porewater properties. However, the variety of early to late diagenetic dolomite phases ... -
The potential of dust detection by means of µXRF scanning in Eifel maar lake sediments
(E&G – Quaternary Science Journal; Vol.60, No. 1)Mittels kontinuierlicher und hochauflösender μXRF-Geochemieanalysen wird die Variabilität äolischer Sedimente der letzten 60.000 Jahre rekonstruiert. Dazu werden zwei Sedimentbohrkerne jeweils aus einem Maarsee und einem ... -
The spatial distribution of sedimentary compounds and their environmental implications in surface sediments of Lake Khar Nuur (Mongolian Altai)
; ; Zech, R.; (Earth Surface Processes and Landforms, 2021-01-26)
Lake sediments are valuable natural archives to reconstruct paleoclimate and paleoenvironmental changes which consist of inorganic and organic sediment compounds of allochthonous origin from the catchment and of autochthonous ...
