Major and trace element analysis of Ca-Mg-carbonates and carbonate melt at 6 and 9 GPa

Sieber, Melanie J. | Wilke, Franziska D. H. | Appel, Oona | Oelze, Marcus | Koch-Müller, Monika

2022

The melting relations of the CaCO3 MgCO3 system are investigated and trace element partition coefficient of Li, Na, K, Mn, Fe, Sr, Ba, Pb, Nb, Y and rare earth elements (REEs) between carbonates (Mg-calcite, Ca-magnesite) and dolomitic melt are established from high pressure (6 and 9 GPa) and...

3D rheological model of the Southern Central Andes

Rodriguez Piceda, Constanza | Scheck-Wenderoth, Magdalena | Cacace, Mauro | Bott, Judith | Strecker, Manfred R.

2021

The southern Central Andes (SCA, 29°S-39°S) are characterized by the subduction of the oceanic Nazca Plate beneath the continental South American Plate. One striking feature of this area is the change of the subduction angle of the Nazca Plate between 33°S and 35°S from the Chilean-Pampean...

Wilke, Franziska D. H.

2022

This data set is the source of my doctoral thesis and of three resulting publications. Through whole rock geochemistry of selected samples and microprobe and geochronological analyses of key minerals, formerly selected by extensive microscopical studies, standard geothermobarometry and...

Accessory Minerals in Felsic Igneous Rocks - Part 9 Monazite-(Ce), xenotime-(Y) and zircon from late-Variscan biotite and two-mica granites of the Aue-Schwarzenberg Granite Zone (Western Erzgebirge−Vogtland metallogenic province, Germany)

Förster, Hans-Jürgen

2021

This data set is Part 9 of a series of data sets dealing with the composition of accessory minerals from felsic igneous rocks compiles chemical data for monazite-(Ce), xenotime-(Y) and zircon from several, late-Variscan granite occurrences in the Aue-Schwarzenberg Granite Zone (ASGZ) located in...

Ultrasonic transmission measurements from six boreholes from the STIMTEC experiment, Reiche Zeche Mine, Freiberg (Saxony, Germany)

Boese, Carolin M. | Kwiatek, Grzegorz | Fischer, Thomas | Plenkers, Katrin | Starke, Juliane | Blümle, Felix | Dresen, Georg | Janssen, Christoph

2021

Between early 2018 and late 2019 the STIMTEC hydraulic stimulation experiment was performed at ca.~130 m below surface at the Reiche Zeche underground research laboratory in Freiberg, Saxony/Germany. The project aimed at gaining insight into the creation and growth of fractures in anisotropic...

Experimental data for permeability and stiffness measurements of fractured Flechtingen sandstone measured with a triaxial compression apparatus

Kluge, Christian | Blöcher, Guido | Hofmann, Hannes | Barnhoorn, Auke | Schmittbuhl, Jean | Bruhn, David

2021

Faults and fractures form the largest contrast of fluid flow in the subsurface, while their permeability is highly affected by effective pressure changes. In this experimental study, fractured low-permeability Flechtingen (Rotliegend) sandstones were cyclically loaded in a MTS tri-axial...

Geochemical and sedimentological data of the Tayma palaeolake record

Neugebauer, Ina | Dinies, Michele | Plessen, Birgit | Dräger, Nadine | Brauer, Achim | Brückner, Helmut | Frenzel, Peter | Gleixner, Gerd | Hoelzmann, Philipp | Krahn, Kim | Noack, Doreen | Pint, Anna | Schwab, Valerie | Schwarz, Anja | Tjallingii, Rik | Vieth-Hillebrand, Andrea | Engel, Max

2021

The data result from a sedimentological and geochemical multiproxy approach to study a Holocene palaeolake record north of Tayma, NW Saudi Arabia. The lacustrine, partly varved record was analysed in the frame of the DFG founded project CLEAR “Holocene climatic events in Northern Arabia -...

Geochemistry of late-Variscan felsic igneous rocks of the Erzgebirge-Vogtland metallogenic province - Part 2: F-poor biotite and two-mica granites

Förster, Hans-Jürgen

2022

This data set is part 2 of this series and compiles whole-rock chemical data for late-Variscan low-F biotite and two-mica granites in the German Erzgebirge, in the Saxothuringian Zone of the Variscan Orogen. The group of F-poor biotite granites is represented by the composite massifs of...

Mineral reflectance spectra and LIBS data of 18 lithium-bearing mineral samples (lepidolite, petalite and spodumene specimen)

Koellner, Nicole | Kuras, Agnieszka | Hildebrand, Constantin | Koerting, Friederike | Kaestner, Friederike

2021

The data set contains LIBS (Laser-Induced Breakdown Spectroscopy) emission spectra of 18 lithium-bearing minerals and their corresponding hyperspectral reflectance spectra. The data were collected within the research project LIGHTS (Lightweight Integrated Ground and Airborne Hyperspectral...

Geochemistry of late-Variscan felsic igneous rocks of the Erzgebirge-Vogtland metallogenic province - Part 1: P- und F-rich Li-mica granites
