The sediment was chemically and mechanically compacted, folded, and faulted during the Hercynian orogeny. The studied microstructure of the Ruhr sandstone indicates depths of up to 6000 m and reconstructed, possible temperatures of over 120 ºC. This results in a complex mineralogical structure compared to other sandstones such as the Berea sandstone or the Fontainbleau sandstone. As part of the Balcewicz et al. (2021) publication, we made a first attempt to study the Ruhr Sandstone using Digital Rock Physics (DRP).<br> <br> This dataset contains the underlying Scanning Electron Microscope (SEM) images used in Balcewicz et al. (2021). The images were obtained on two thin sections of the Ruhr sandstone (RSST_X_02_25 & RSST_X_02_75).Ruhr-Universität Bochum, Faculty of Geosciences
