Laboratory Sandstone Micro-CT Volume Data for Porosity-Controllable Generation of Three-Dimensional Porous Geomaterials
Abstract
This dataset contains laboratory sandstone micro-CT volume data and associated metadata used in the study entitled “A Porosity-Controllable Generative Framework for Three-Dimensional Porous Geomaterials Based on Discrete Latent-Space Diffusion”. The micro-CT volume represents a binary sandstone digital core with a size of 800 × 800 × 800 voxels and a voxel resolution of 3.5 μm/voxel. In the binary volume, voxel value 0 denotes the solid matrix and voxel value 1 denotes the pore space. The dataset is provided to support the construction of training samples and the development of porosity-controllable three-dimensional porous geomaterial generation models. The associated metadata file describes the data format, voxel size, image dimensions, voxel-value convention, and basic usage information. The Fontainebleau sandstone digital rock samples used for independent validation in the associated manuscript were obtained from a previously reported Australian National University (ANU) digital rock dataset and are not redistributed in this repository.
