3D rheological model of the Southern Central Andes
Rodriguez Piceda, Constanza | Scheck-Wenderoth, Magdalena | Cacace, Mauro | Bott, Judith | Strecker, Manfred
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...
Isotopic data of pyrite (δ34S) and barite (δ34S, δ18O) in the Canol Formation (Selwyn Basin, Canada)
Grema, Haruna M. | Magnall, Joseph M. | Whitehouse, Martin J. | Gleeson, Sarah A. | Schulz, Hans -M.
2021
The stable isotopic composition of pyrite (δ34Spyrite) and barite (δ34Sbarite, δ18Obarite) in marine sedimentary rocks provides a valuable archive for reconstructing the biogeochemical processes that link the sulfur, carbon, and iron cycles. Highly positive δ34Spyrite values that exceed...
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...
CT data, PIV analysis results and surface view videos of analogue models of interacting crustal and mantle weaknesses during rifting
Zwaan, Frank | Chenin, Pauline | Erratt, Duncan | Manatschal, Gianreto | Schreurs, Guido
2021
This data set includes videos depicting the surface evolution (time laps photographs and Particle Image Velocimetry or PIV analsys) of 15 analogue models on rift tectonics, as well as 4D CT imagery (figures and videos) from four of these experiments. The experiments examined the influence of...
Surface displacement, self-attraction and loading and M2 ocean tide fields in view of anelastic solid Earth models
Huang, Pingping | Sulzbach, Roman | Tanaka, Yoshiyuki | Klemann, Volker | Dobslaw, Henryk | Martinec, Zdeněk | Thomas, Maik
2021
As a supplement to Huang et al. (2021) “Anelasticity and lateral heterogeneities in Earth’s upper mantle: impact on surface displacements, self-attraction and loading and ocean tide dynamics”, the global amplitude and root-mean-square fields of surface vertical displacement and...
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...
Source parameters of Acoustic Emissions from triaxial experiments on Westerly granite, Aue Granite and Flechtigen Sandstone
Goebel, Thomas | Kwiatek, Grzegorz | Stanchits, Sergei | Davidsen, Joern
2021
This dataset is supplementary material to "What controls the presence and characteristics of aftershocks in rock fracture in the lab?" by Joern Davidsen, Thomas H. W. Goebel, Grzegorz Kwiatek, Sergei Stanchits, Jordi Baro and Georg Dresen (Davidsen et al., 2021). The dataset contains...
Analysis of cosmogenic 10Be concentrations of Siwalik sediments and modern river sands from the north-western Himalaya and the calculated 10Be-derived paleoerosion rates
Mandal, Sanjay Kumar | Scherler, Dirk | Wittmann, Hella
2021
These datasets were used to evaluate the main controls on last ~6 million years erosion rate variability of the northwestern Himalaya. The Earth’s climate has been cooling during the last ~15 million years and started fluctuating between cold and warm periods since ~2-3 million years ago....
A global database of radiogenic Nd and Sr isotopes in marine and terrestrial samples (V. 3.0)
Blanchet, Cécile L.
2021
The database presented here contains radiogenic neodymium and strontium isotope ratios measured on both terrestrial and marine sediments. It was compiled to help assessing sediment provenance and transport processes for various time intervals. This can be achieved by either mapping sediment...

Poppe, Sam | Holohan, Eoghan P. | Rudolf, Michael | Rosenau, Matthias | Galland, Olivier | Delcamp, Audray | Van Gompel, Gert | Buls, Nico | Soens, Bastien | Pohlenz, Andre | Mourgues, Régis | Kervyn, Matthieu
2021
This dataset provides mechanical test data for quartz sand (“MAM1ST-300”, Sibelco, Mol, Belgium), gypsum powder (plaster; “Goldband”, Knauf), kaolin clay powder, garnet sand, and mixtures of quartz sand and gypsum powder, used at the Analogue Laboratory of the Department of Geography at the...
