Mafic Late Miocene–Quaternary volcanic rocks in the Kamchatka back arc region: implications for subduction geometry and slab history at the Pacific–Aleutian junction
Volynets, Anna; Churikova, Tatiana;
; Gordeychik, Boris; Layer, Paul (Contributions to Mineralogy and PetrologyContributions to Mineralogy and Petrology, 2009)
New 40Ar/39Ar and published 14C ages constrain voluminous mafic volcanism of the Kamchatka back-arc to Miocene (3–6 Ma) and Late Pleistocene to Holocene (<1 Ma) times. Trace elements and isotopic compositions show that ... -

Major shear zones of southern Brazil and Uruguay: escape tectonics in the eastern border of Rio de La plata and Paranapanema cratons during the Western Gondwana amalgamation
(International Journal of Earth Sciences, 2010)The Mantiqueira Province represents a series of supracrustal segments of the South-American counterpart formed during the Gondwana Supercontinent agglutination. In this crustal domain, the process of escape tectonics played ... -
Making Fe0-Based Filters a Universal Solution for Safe Drinking Water Provision
Naseri, Elham; Ndé-Tchoupé, Arnaud; Mwakabona, Hezron; Nanseu-Njiki, Charles;; Njau, Karoli; Wydra, Kerstin (Sustainability, 2017)
Metallic iron (Fe0)-based filtration systems have the potential to significantly contribute to the achievement of the United Nations (UN) Sustainable Development Goals (SDGs) of substantially improving the human condition ... -
Mantle Convection Patterns Reveal the Mechanism of the Red Sea Rifting
; ; ; Al-Arifi, N. (Tectonics, 2020)
We present a new model of the stress state and present-day tectonics of the Red Sea Rift (RSR) based on an instantaneous geodynamic mantle flow model. The initial density and viscosity variations in the mantle are derived ... -
Mapping leaf area index over semi-desert and steppe biomes in kazakhstan using satellite imagery and ground measurements
(EARSeL eProceedings, 2009)Maps of peak seasonal leaf area index (LAI) were produced using the Normalised Difference Vegetation Index (NDVI) from SPOT VEGETATION (VEG) satellite at 1 km resolution over a large region in the semi-arid zone of Kazakhstan. ... -
Marble bowing: comparative studies of three different public building facades
(Environmental geologyEnvironmental geology, 2008)The veneer cladding of the Oeconomicum (OEC, Göttingen), the State Theatre of Darmstadt (STD, Darmstadt) and of the State and University Library (SUB, Göttingen) is characterised by pronounced bowing after a short time of ... -
Mass-transport deposits and reservoir quality of Upper Cretaceous Chalk within the German Central Graben, North Sea
Arfai, Jashar; Lutz, Rüdiger;; Gaedicke, Christoph; (International Journal of Earth Sciences, 2015)
The architecture of intra-chalk deposits in the ‘Entenschnabel’ area of the German North Sea is studied based on 3D seismic data. Adapted from seismic reflection characteristics, four types of mass-transport deposits (MTDs) ... -

Mechanical Modeling of Pre‐Eruptive Magma Propagation Scenarios at Calderas
; ; (Journal of Geophysical Research: Solid Earth, 2023-02-24)
Simulating magma propagation pathways requires both a well‐calibrated model for the stress state of the volcano and models for dike advance within such a stress field. Here, we establish a framework for calculating ... -
Mechanism of uranium fixation by zero valent iron: the importance of co-precipitation
; Meinrath, G.; Volke, P.; Peter, H.-J.; Dietrich, P.; Merkel, B. (Uranium in the aquatic environment, 2002)
The coprecipitation of U (VI) with iron corrosion products from aqueous solutions by zero valent iron was investigated. The evidence of coprecipitation was demonstrated by conducting experiments with well characterized ... -
Mechanism of Uranium Removal from the Aqueous Solution by Elemental Iron
; Schöner, A.; Meinrath, G. (Journal of Hazardous Materials, 2006)
The effectiveness of elemental iron (Fe0) to remove uranium (U) from the aqueous phase has been demonstrated. While the mitigation effect is sure, discrepancies in the removal mechanism have been reported. The objective ... -
Mega-monsoon variability during the late Triassic: Re-assessing the role of orbital forcing in the deposition of playa sediments in the Germanic Basin
; Kolber, Gilles; Kaboth-Bahr, Stefanie; Reinhardt, Lutz; ; Pross, Jörg (Sedimentology, 2019)
The formation of the supercontinent Pangaea during the Permo–Triassic gave rise to an extreme monsoonal climate (often termed ‘mega-monsoon’) that has been documented by numerous palaeo-records. However, considerable debate ... -
Mega‐scale glacial lineations formed by ice shelf grounding in the Canadian Beaufort Sea during multiple glaciations
; Dallimore, Scott; Wamsteeker, Michael; Taylor, Gary; King, Edward L.; Rohr, Kristin M. M.; Hong, Jong Kuk; Jin, Young Keun (Earth Surface Processes and Landforms, 2021-05-05)
Mega‐scale glacial lineations formed by the raking of ice shelves across the seafloor have been reported from multiple polar regions. Here, we present the first evidence of continental slope situated buried lineations in ... -
