Calcite precipitation in fractured basalt: Case 2 (Run2_HF)

This dataset provides X-ray computed tomography (CT) images of fractured basalt cores acquired during the injection of supersaturated solution with respect to calctie. In this experiment, we employed two distinct flow rates (1 mL/min; Run1_LF and 5 mL/min; Run2_HF) to elucidate the effect of flow rate on porosity changes, fracture-matrix interaction, and precipitation pattern. This image set includes the baseline scans and post-precipitation images captured at different injection times during the 5 mL/min test. Run2_HF images have voxel size of 52.0 microns and voxel depth of 43.9 microns. Images of a high flow rate (1 mL/min; Run1_LF) can be found in a dataset with the name 'Calcite precipitation in fractured basalt: Case 1 (Run1_LF)'本数据集提供了在注入相对于方解石过饱和溶液过程中采集的破裂玄武岩岩心的X射线计算机断层扫描（CT）图像。本实验采用两种不同的流速（1 mL/min；Run1_LF 与 5 mL/min；Run2_HF），以阐明流速对孔隙度变化、裂缝-基质相互作用以及沉淀模式的影响。该图像集包含5 mL/min实验中不同注入时刻采集的基线扫描图像与沉淀后图像。Run2_HF图像的体素尺寸为52.0微米，体素深度为43.9微米。高流速（1 mL/min；Run1_LF）的图像可在名为“破裂玄武岩中方解石沉淀：案例1（Run1_LF）”的数据集中获取。
