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.
The method employed in the article, from which the data are derived, is the 14C-PMMA autoradiographic method. <br> The heart of the 14C-PMMA method consists of impregnating a sample with liquid 14C-labelled MethylMethAcrylate (14C-MMA), its subsequent polymerisation in the pore space, and autoradiography of the impregnated sample after sowing and polishing, giving a connected porosity map of the studied rock section. The method can also be adapted to determine crack apertures.
In the article, we proposed an advanced calibration of the 14C-PMMA autoradiographic method for quantifying real crack apertures by taking into account the variability of tilt angle encountered in natural rock samples. To this aim, a set of artificial crack samples presenting different controlled apertures and tilt angles was used, as well as Monte Carlo simulations through Geant4 toolkit.
