Acoustic Emission and Seismic moment tensor catalogs associated with triaxial stick-slip experiments performed on Westerly Granite samples

The dataset contains source parameters of acoustic emission (AE) events recorded during triaxial friction (stick-slip) experiments performed on the Westerly Granite sample WgN05. In addition we provide raw waveform data of AE events recorded in triggered mode with a network of 16 AE sensors. Basic seismic catalog associated with the stick-slip experiment contains origin time, hypocentral location in local Cartesian coordinate system of the sample (with associated uncertainties), and AE-derived magnitude. In addition, for a subset of AEs we provide full moment tensors. This catalog include information on fault parameters (strike, dip and rake of the two nodal planes), percentage of isotropic, compensated linear vector dipole and double-couple components of the full moment tensor, P, T, B axes orientations in the coordinate system of the sample, uncertainty assessment, as well as the six independent moment tensor components. Finally, we provide a time series of axial stress values as presented in the Kwiatek et al. (2023) as well as the coordinates of the AE sensors. The catalog and parametric data is supplemented with the raw waveform recordings stored in HDF5 format from 16 acoustic emission sensors placed on the surface of the sample.

Source parameters of Acoustic Emissions from triaxial experiments on Westerly granite, Aue Granite and Flechtigen Sandstone

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 source parameters of acoustic emission events recorded during triaxial fracture and friction (stick-slip) experiments performed on two Westerly Granite samples, Aue Granite and Flechtigen Sandstone. Basic seismic catalog associated with each experiment contains origin time, hypocentral location in local Cartesian coordinate system of the sample, acoustic-emission derived magnitude and polarity coefficient (a simplified measure of mechanism type: shear, pore opening or collapse). Extended catalog information is available for selected experiments including information whether event is background seismicity, trigger of following events or triggered by preceding events. In addition, we provide information on focal mechanisms calculated in each experiment using full moment tensor inversion. Focal mechanism catalogs include information on strike, dip and rake of two nodal planes, and percentage of isotropic, clvd and double-couple components of the full moment tensor. The detailed description of catalog is provided in the data description file which is also included in the zip folder of the data.

Program codes used under Geant4 toolkit and IDE Code::Blocks to simulate the 14C-PMMA autoradiographic method and analyze the data, respectively, for better calibration of the determination of cracks aperture in rocks with this method.

These program codes are part of the manuscript entitled "Determining crack apertures distribution in rocks using 14C-PMMA autoradiographic method: experiments and simulations" by Bonnet et al. (2019)All the codes are including in one zip file. It contains:- one text file describing the content of the zip file {ReadMe.txt},- the program used under Geant4 for the simulations {Geant4_Program folder},- and the program used under the IDE Code::Blocks {CodeBlockEnergyProfiles.cpp}.

High-angular resolution electron backscatter diffraction data (HR-EBSD) from olivine and quartz

This dataset is supplemental to the paper Wallis et al. (2019) and contains data derived from distortion of crystal lattices measured using conventional electron backscatter diffraction (EBSD) and high-angular resolution electron backscatter diffraction (HR-EBSD). The datasets include lattice misorientation, elastic-strain heterogeneity, residual-stress heterogeneity, and densities of geometrically necessary dislocations in olivine and quartz. We intend the data and associated paper to demonstrate key aspects of the HR-EBSD technique and to draw comparisons with conventional EBSD. As the paper by Wallis et al. (2019) is a review paper, several of the datasets have also been present in, or are otherwise related to, additional previous publications listed below .Data are provided as 55 tab delimited .txt files organised by the figure in which they appear within Wallis et al. (2019). Data types are indicated in the file names. Please consult the data description file for detailed explanations.

Data set including raw data from the Geant4 simulations (energy profiles), a file with the data from the energy profiles extracted with a code under Code::Blocks, 2 scans of autoradiographs (perpendicular and tilted cracks), and 1 image of two artificial crack samples.

This data set is part of the manuscript entitled "Determining crack apertures distribution in rocks using 14C-PMMA autoradiographic method: experiments and simulations" by Bonnet, M., Sardini, P., Billon, S., Siitari-Kauppi, M., Kuva, J., Fonteneau, L., & Caner, L. which is currently under review in Journal of Geophysical Research: Solid Earth.All the data set are including in one zip file. It contains:- one text file describing the content of the zip file {ReadMe.txt},- the raw data of the energy profiles obtained by simulations {RawDataEnergyProfiles folder},- one excel file with the data extracted from the energy profiles with Code::Blocks {DataExtractedEnergyProfiles.xlsx},- one image file of two artificial samples (at left with a real aperture of 96 µm and a tilt angle of 90°; at right with a real aperture of 189 µm and a tilt angle of 20°) {ExEch.pdf},- one image file of the scan autoradiograph of perpendicular artificial cracks {AG_Texp8h_1200dpi_Ech90deg.pdf},- and one image file of the scan autoradiograph of tilted artificial cracks {AG_Texp8h_1200dpi_EchTilted.pdf}.The authors provide raw data from the simulations (.txt and .xlsx), as well as some photos of the experimental part (.pdf).Raw data from the simulations are energy profiles (.txt) obtained with Geant4 toolkit. The simulated object is an artificial crack sample in-filled with a radioactive resin (14C-MMA) which is in contact with an autoradiographic film (also simulated), simulating the 14C-PMMA autoradiographic method. Crack aperture and tilt angle (of the crack to the autoradiographic plane) are varying parameters (from [0.1; 1000] µm and from [10; 90]°, respectively).Other raw data from the simulations is one excel file with the data extracted from the energy profiles with the IDE Code::Blocks, for data analysis purposes.Three photos of the experimental part of the article are also made available. One image file of two artificial samples with different crack aperture and tilt angle; one image file of the scan autoradiograph of perpendicular artificial cracks; and one image file of the scan autoradiograph of tilted artificial cracks.
