Assessing the utility of trace and rare earth elements as biosignatures in microbial iron oxyhydroxides
Heim, Christine; Simon, Klaus; Ionescu, Danny; Reimer, Andreas; De Beer, Dirk; Quéric, Nadia-Valérie; Reitner, Joachim; Thiel, Volker (Frontiers in Earth Science, 2015)Microbial iron oxyhydroxides are common deposits in natural waters, recent sediments, and mine drainage systems. Along with these minerals, trace and rare earth elements (TREE) are being accumulated within the mineralizing ... -
Catshark egg capsules from a Late Eocene deep-water methane-seep deposit in western Washington State, USA
Fossil catshark egg capsules, Scyliorhinotheca goederti gen. et sp. nov., are reported from a Late Eocene deep−water methane−seep calcareous deposit in western Washington State, USA. The capsules are preserved three−dimensionally ... -
Chaotic three-dimensional distribution of Ba, Rb, and Sr in feldspar megacrysts grown in an open magmatic system
Słaby, Ewa; Śmigielski, Michał; Śmigielski, Tomasz; Domonik, Andrzej; Simon, Klaus; Kronz, Andreas (Contributions to Mineralogy and Petrology, 2011)As has been demonstrated in recent years, the heterogeneities of coeval magmas can be more successfully revealed by zoned megacrysts rather than by analysis of the whole rocks hosting them. Here, the geochemical ... -
Chemical characteristics (REE, etc.) of Paleozoic and Mesozoic graywackes and sandstones from Central Europe
Wedepohl, Karl Hans; Simon, Klaus (Contributions to Mineralogy and Petrology, 2012)During the Variscan orogeny in Central Europe, partial melting in the lower continental crust formed granitic magmas, which intruded into the upper crust and left compounds of Ca (plus Eu2+), Mg, etc. in the lower crust. ... -
Deciphering fluid inclusions in high-grade rocks
van den Kerkhof, Alfons; Kronz, Andreas; Simon, Klaus (Geoscience Frontiers, 2014)The study of fluid inclusions in high-grade rocks is especially challenging as the host minerals have been normally subjected to deformation, recrystallization and fluid-rock interaction so that primary inclusions, formed ... -
Description of an aerodynamic levitation apparatus with applications in Earth sciences
Pack, Andreas; Kremer, Katrina; Albrecht, Nina; Simon, Klaus; Kronz, Andreas (Geochemical Transactions, 2010)Background: In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. In combination with CO2-laser heating, containerless melting at high temperature of oxides and silicates is possible. We ... -
Effects of sample storage and shell orientation on LA-ICPMS trace element measurements on deep-sea mussels.
Génio, Luciana; Simon, Klaus; Kiel, Steffen; Cunha, Marina R. (Scientific reports, 2015)Geochemical markers are being increasingly applied to fundamental questions in population and community ecology in marine habitats because they allow inferences on individuals dispersal, but vital effects, small sample ... -
Fluid/rock interaction and mass transfer in continental subduction zones: constraints from trace elements and isotopes (Li, B, O, Sr, Nd, Pb) in UHP rocks from the Chinese Continental Scientific Drilling Program, Sulu, East China
Xiao, Yilin; Hoefs, Jochen; Hou, Zhenhui; Simon, Klaus; Zhang, Zeming (Contributions to Mineralogy and Petrology, 2011)In order to better understand the role of fluids during subduction and subsequent exhumation, we have investigated whole-rock and mineral chemistry (major and trace elements) and Li, B as well as O, Sr, Nd, Pb isotopes on ... -
Hydrogen incorporation in enstatite in the system MgO-SiO2-H2O-NaCl
Stalder, Roland; Kronz, Andreas; Simon, Klaus (Contributions to mineralogy and petrologyContributions to mineralogy and petrology, 2008)The incorporation of hydrogen in enstatite in a hydrous system containing various amounts of NaCl was investigated at 25 kbar. The hydrogen content in enstatite shows a clear negative correlation to the NaCl-concentration ... -
Isotope and REE Characterization of Groundwater Aquifers within the Aquifer Storage and Recovery Programme in Sukhothai (N.-Thailand)
Hengsuwan, Manussawee; Yongprawat, Monthon; Simon, Klaus; Hansen, Bent T. (Journal of Water Resource and Protection, 2016)Aquifer Storage and Recovery (ASR) was a pilot project for solving flood and drought problem in the northern part of Chao Phraya River basin, Thailand. This part of Thailand always faces flooding in rainy season and ... -
Protomylonite evolution potentially revealed by the 3D depiction and fractal analysis of chemical data from a feldspar
Słaby, Ewa; Domonik, Andrzej; Śmigielski, Michał; Majzner, Katarzyna; Motuza, Gediminas; Götze, Jens; Simon, Klaus; Moszumańska, Izabela; Kruszewski, Łukasz; Rydelek, Paweł (Contributions to Mineralogy and Petrology, 2014)An alkali feldspar megacryst from a protomylonite has been studied using laser ablation-ICP-mass spectrometry combined with cathodoluminescence imaging, Raman spectroscopy, and electron probe microanalysis. The aim was to ... -
Trachyte weathering in the urban built environment related to air quality
Germinario, Luigi; Siegesmund, Siegfried; Maritan, Lara; Simon, Klaus; Mazzoli, Claudio (Heritage Science, 2017)Decay of trachyte used as building stone in urban environment was investigated through the analysis of crusts and patinas found on trachyte of the Euganean Hills in the Renaissance city walls of Padua, northeastern Italy. ...
