Laboratory Sandstone Micro-CT Volume Data for Porosity-Controllable Generation of Three-Dimensional Porous Geomaterials

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.本数据集包含发表于题为《基于离散潜空间扩散的孔隙度可控三维多孔岩土材料生成框架》的研究中的实验室砂岩显微CT（micro-CT）体数据及相关元数据。该显微CT体数据为尺寸800×800×800体素、体素分辨率3.5 μm/体素的二值化砂岩数字岩心。在该二值体数据中，体素值0代表固体基质，体素值1代表孔隙空间。 本数据集旨在支撑训练样本构建与孔隙度可控三维多孔岩土材料生成模型的研发工作。配套元数据文件详细说明了数据格式、体素尺寸、图像维度、体素值约定及基础使用信息。 相关论文中用于独立验证的枫丹白露砂岩数字岩心样本，取自此前公开报道的澳大利亚国立大学（Australian National University, ANU）数字岩心数据集，并未在此仓库中重新分发。
