Biogeochemical processes in subseafloor sediments are closely coupled to global element cycles. To improve the understanding of changes in biogeochemical conditions on geological timescales, we investigate sediment cores ... -
Evolution of a hydrothermal ore-forming system recorded by sulfide mineral chemistry: a case study from the Plaka Pb–Zn–Ag Deposit, Lavrion, Greece
; ; ; ; ; (Mineralium Deposita, 2021-08-28)
Laser ablation-inductively coupled plasma-mass spectrometry and electron-probe microanalysis were used to investigate the trace-element contents of sphalerite, chalcopyrite and pyrite from the Plaka Pb–Zn–Ag deposit. Using ... -
Evolution of an Atmospheric Kármán Vortex Street From High-Resolution Satellite Winds: Guadalupe Island Case Study
; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2020)
Vortex streets formed in the stratocumulus-capped wake of mountainous islands are the atmospheric analogues of the classic Kármán vortex street observed in laboratory flows past bluff bodies. The quantitative analysis of ... -
Evolution of convective characteristics during tropical cyclogenesis
(Quarterly Journal of the Royal Meteorological Society, 2021-04-05)
Four idealized, high‐resolution (500 m horizontal grid spacing), numerical simulations are used to investigate the evolution of convective structures during tropical cyclogenesis. The simulations all begin with a weak ... -
Evolution of diagenetic conditions and burial history in Buntsandstein Gp. fractured sandstones (Upper Rhine Graben) from in-situ δ18O of quartz and 40Ar/39Ar geochronology of K-feldspar overgrowths
; ; ; ; ; ; ; (International Journal of Earth Sciences, 2021-07-09)
In-situ δ18O measured in the quartz overgrowths help identify temperature and fluid origin variations responsible for cementation of the pore network (matrix and fracture) in the Buntsandstein Gp. sandstone reservoirs ... -
Evolution of Global Ocean Tide Levels Since the Last Glacial Maximum

Evolution of Lamayuru palaeolake in the Trans Himalaya: Palaeoecological implications
(E&G – Quaternary Science Journal; Vol.48, No. 1)Vor etwa 35 000-40 000 Jahren schuf eine Episode neotektonischer Aktivität an der Indus-Sutur bei Lamayuru (Ladakh) einen See, von dem eine über 105 m mächtige Abfolge fluviolakustriner Ablagerungen erhalten ist. Die ... -
Evolution of Magmatism in the New Hebrides Island Arc and in Initial Back-Arc Rifting, SW Pacific
; ; Lima, S. M.; ; ; Romer, R. L.; Bellon, H. (Geochemistry, Geophysics, Geosystems, 2020)
We present new geochemical and isotopic data for rock samples from two island arc volcanoes, Erromango and Vulcan Seamount, and from a 500 m thick stratigraphic profile of lava flows exposed on the SW flank of Vate Trough ... -
Evolution of Rift Systems and Their Fault Networks in Response to Surface Processes
; ; ; ; ; (Tectonics, 2022-02-24)
Continental rifting is responsible for the generation of major sedimentary basins, both during rift inception and during the formation of rifted continental margins. Geophysical and field studies revealed that rifts feature ... -
Evolution of Sea Surface Hydrology Along the Western Australian Margin Over the Past 450 kyr
; ; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2021-11-05)
We collected a suite of core top samples during R/V Sonne Cruise SO257 in May 2017 along the southwestern front of the Indo‐Pacific Warm Pool (IPWP) to monitor the variability of Southern Hemisphere tropical and subtropical ... -
Evolution of the Geomagnetic Daily Variation at Tatuoca, Brazil, From 1957 to 2019: A Transition From Sq to EEJ
; ; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2020)
The magnetic equator in the Brazilian region has moved over 1,100 km northward since 1957, passing the geomagnetic observatory Tatuoca (TTB), in northern Brazil, around 2013. We recovered and processed TTB hourly mean ... -
