CT data, PIV analysis results and surface view videos of analogue models of interacting crustal and mantle weaknesses during rifting

Frank Zwaan, Pauline Chenin, Duncan Erratt, Gianreto Manatschal & Guido Schreurs
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 differently oriented mantle and crustal weaknesses on rift system development using a brittle-viscous set-up. All experiments were performed at the Tectonic Modelling Laboratory of the University of Bern (UB)....

Matlab Script FAST Calibration v.2.0

Moritz O. Ziegler & Oliver Heidbach
The 3D geomechanical-numerical modelling aims at a continuous description of the stress state in a subsurface volume. The model is fitted to the model-independent stress data records by adaptation of the displacement boundary conditions. This process is herein referred to as model calibration. Depending on the amount of available stress data records and the complexity of the model the calibration can be a lengthy process of trial-and-error to estimate the best-fit boundary conditions. The tool...

Stress strain data of experimentally deformed Carrara marble in the semi-brittle field

Erik Rybacki, Lu Niu & Brian Evans
The data set contains stress-strain data of Carrara marble experimentally deformed in triaxial compression at temperatures of 20 – 800°C, confining pressures of 30 – 300 MPa, and strain rates between 10-3 and 10-6 s-1. This range covers conditions, at witch marble deforms in the semi-brittle regime, i.e., strength depends on all parameters, but with different sensitivity. Semi-brittle deformation behavior is expected to be important in the mid continental crust. The experiments were conducted in...

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

Christian Kluge, Guido Blöcher, Hannes Hofmann, Auke Barnhoorn, Jean Schmittbuhl & David Bruhn
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 compression cell. Two different loading scenarios were considered: “continuous cyclic loading” (CCL) and “progressive cyclic loading” (PCL). During continuous cyclic loading, a displaced tensile fracture was loaded hydrostatically from 2 to 60 MPa in several repeated...

Deep seismic reflection profile DEKORP 1986-2Q across the Muensterland Basin, Northwest Germany

Manfred Stiller, Lauretta Kaerger, Tatiana Agafonova, Charlotte Krawczyk, Onno Oncken, Michael Weber, , &
The ca. 60 km long seismic line DEKORP 2Q was recorded in 1986 as part of the DEKORP project, the German deep seismic reflection program. The survey was carried out to investigate possible NW-SE trending crustal structure of the Muensterland Basin with high-fold near-vertical incidence vibroseis acquisition. A detailed description of seismic results is provided by Franke et al. (1990) and supplemented by many other researches. The Technical Report of line 2Q gives complete information...

Continuous monitoring of soil CO2 efflux and atmospheric parameters at the Los Humeros Volcanic Complex

Anna Jentsch, Walter Duesing, Egbert Jolie & Martin Zimmer
Carbon dioxide is the most abundant, non-condensable gas in volcanic systems, released into the atmosphere through either diffuse or advective fluid flow. The emission of substantial amounts of CO2 at Earth’s surface is not only controlled by volcanic plumes during periods of eruptive activity or fumaroles, but also by soil degassing along permeable structures in the subsurface. Monitoring of these processes is of utmost importance for volcanic hazard analyses, and is also relevant for managing...

Geochemical data on silicon isotope and Ge/Si ratios along a global erodosequence

Patrick Frings, Marcus Oelze, Daniel A. Frick & Friedhelm von Blanckenburg
We provide geochemical data for three sites that define a gradient of erosion rates – an “erodosequence”. These sites are the Swiss Central Alps, a rapidly-eroding post-glacial mountain belt; the Southern Sierra Nevada, USA, eroding at moderate rates; and the slowly-eroding tropical Highlands of central Sri Lanka. Specifically, we provide silicon isotope ratios and germanium/silicon ratios and the major element composition of 1) rock, 2) saprolite, 3) soil, 4) plants, 5) river dissolved loads, 6)...

GRACE-FO calibrated and characterized magnetometer data

Ingo Michaelis, Claudia Stolle & Martin Rother
GRACE-FO carries a magnetometer as part of its attitude orbit control system (AOCS). The magnetometer does not belong to the scientific payload of the mission. However, after postprocessing of the data, information on the geomagnetic field and on electric currents in near Earth space are derived. Each GRACE-FO satellite (GF1 and GF2) carries two fluxgate magnetometers (FGM), an active one, FGM A, and a redundant one, FGM B. So far, the redundant magnetometers were not...

Long-period magnetotelluric data collected on the north-east Greenland Ice Sheet, 2019

Kate Selway, Clint Conrad, Maaike Weerdesteijn & Silje Smith-Johnsen
The goal of MAGPIE is to improve estimates of present-day ice melting rates in Greenland by accurately correcting observed uplift rates for glacial isostatic adjustment (GIA) from past deglaciation. A key parameter required for constraining uplift rates for GIA is mantle viscosity, which can best be calculated from combined seismic and MT measurements. The data in this repository represent the first year of MAGPIE data collection. This data publication (10.5880/GIPP-MT.201913.1) encompasses a detailed report in...

Magnetotelluric Study of the Hangai Dome, Mongolia: Phase I

Michael Becken, Alexey V. Kuvshinov, Matthew J. Comeau & Johannes Käufl
Surface deformation in the continental interior, away from active tectonic margins, is enigmatic, with the underlying mechanisms responsible not fully understood. Therefore, it is considered an open and important question in continental dynamics. The Hangai Dome, central Mongolia, is a natural laboratory to explore this question. It is a high-elevation, low-relief, intra-continental region within the Mongolian plateau. It is located between the Siberian and North China cratons and lies within the Central Asian Orogenic Belt....
