Mineralogy and Element geochemistry of volcanic rocks and sediments from the central Rift in Kenya
Wilke, Franziska | Olaka, Lydia | Schleicher, Anja
2020
The Central Rift in Kenya (CRK) comprises the lakes Naivasha, Elementaita and Nakuru and the Longonot, Eburru and Menengai volcanos. The alkaline magmas, produced by the volcanoes within the CRK, lead to solid rocks likes trachytes, phonolites, and fewer basalts and accompanied soft rocks...
Denudation and weathering rates of carbonate landscapes from meteoric 10Be/9Be ratios
Wittmann, Hella | Bouchez, Julien | Calmels, Damien | Gaillardet, Jerome | Frick, Daniel | Stroncik, Nicole | ASTER Team | von Blanckenburg, Friedhelm
2024
We provide sample information and geochemical data for obtaining erosion, weathering, and denudation rates from a framework based cosmogenic meteoric 10Be versus stable 9Be (10Be/9Be) ratios. We modified this published silicate framework (von Blanckenburg et al., 2012) to carbonate...
Kaghan Valley, Pakistan: metamorphic rocks, their chemistry and age
Wilke, Franziska
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...
A database of physical experiments, fieldwork information, and a seismic line applied on the eastern Domeyko Cordillera, northern Chile
López, Cristopher | Del Ventisette, Chiara | Bonini, Marco | Montanari, Domenico | Maestrelli, Daniele | Martínez, Fernando | Rioseco, Mitchelle | Cisternas, Renato | Espinoza, Sebastián | Herrera, Bastián | González, Rodrigo | Riquelme, Rodrigo | Navea, Matías
2024
This dataset contains a series of analog models for comparing and testing positive tectonic inversion mechanisms and wedge structure formation. Furthermore, it includes a 2-D seismic reflection profile that can be compared with the models presented here. Finally, several photos of some...
Petrography, quantitative mineralogy, and U-Pb geochronology of the Boundary Zone Zn-Pb-Ag prospect, Yukon, Canada
Grema, Haruna M. | Wudarska, Alicja | Wilke, Franziska D.H. | Schleicher, Anja M. | Milton, Jack E. | Magnall, Joseph M. | Gleeson, Sarah A. | Schulz, Hans-Martin
2024
The Boundary Zone prospect (Yukon, Canada) is a Zn-Pb-Ag prospect hosted by siliciclastic rocks in the Macmillan Pass district. The main host units comprise the Late Ordovician to Early Silurian Duo Lake Formation and the Middle to Late Devonian Portrait Lake Formation. Sulfide mineralization...
Borehole and core measurement data for the rock mass characterization of ICDP expedition 5071, DIVE (Drilling the Ivrea-Verbano zonE), borehole 5071_1_B
Li, Junjian | Caspari, Eva | Greenwood, Andrew | Pierdominici, Simona | Baron, Ludovic | Kück, Jochem | Lemke, Kim | Hetényi, György
2024
To structurally and petrophysically characterize the rock mass in the Ivrea-Vebarno Zone, a comprehensive downhole geophysical dataset from has been collected in borehole 5071_1_B (IGSN ICDP5071EH30001) of the ICDP-DIVE project located in the Central part of the Ivrea-Verbano Zone at the...
Data for Microstructural and Micromechanical Evolution of Olivine Aggregates During Transient Creep
Wiesman, Harison S. | Breithaupt, Thomas | Wallis, David | Hansen, Lars N.
2024
This dataset is supplemental to the paper Wiesman et al. (In prep) and contains data on the density of dislocations and their stress fields in olivine from laboratory experiments to examine transient creep in olivine. The data were used to characterize the microstructural evolution that...
Major and trace element analysis of Ca-Mg-carbonates and carbonate melt at 6 and 9 GPa
Sieber, Melanie J. | Wilke, Franzsika 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...
Geochemical compositions of igneous rocks of the Central Andean orocline
Wörner, Gerhard | Mamani, Mirian
2021
Compilation of more than 1500 major- and trace-element data points, and 650 Sr-, 610 Nd-, and 570 Pb-isotopic analyses of Mesozoic-Cenozoic (190–0 Ma) magmatic rocks in southern Peru, northern Chile and Bolivia (Central Andean orocline). This compilation was initially published by Mamani et al....
Mo, Sr, Nd isotopes and major and trace element concentrations for lavas and enclaves from Solander Volcano, basement rocks and one altered oceanic basalt
Bezard, Rachel | Rushmer, Tracy | Turner, Simon | Eroglu, Sümeyya
2023
The dataset contains major, trace element concentrations and Mo (stable), Sr (radiogenic) and Nd (radiogenic) isotope composition of lavas and enclaves from Solander Volcano (Solander and Little Solander Islands) as well as local basement rocks (xenoliths or borehole samples) and one local...
