Kakkonda Granite: X-ray CT and Topological Analysis of Micropores

188.3 MB of data from the Kakkonda geothermal field includes movies of micropore networks and binary images of pores from X-ray CT scans. The collection also contains persistent diagrams and a table of principal component scores and specific surface area derived from topological data analysis. Author Atsushi Okamoto published this dataset on figshare under a CC-BY-4.0 license, with a last update in May 2026.

Use Cases

• Analyzing 3D micropore network connectivity based on the provided M4V movie files.
• Applying topological data analysis to pore structures using the provided persistent diagrams (PD0, PD1).
• Correlating pore geometry with surface area using the provided table of PC scores and specific surface area.
• Segmenting and visualizing pore spaces from the provided binary image files.

Strengths

• Dataset size is 188.3 MB, indicating a medium-scale collection of files.
• Includes multiple data representations: movies, binary images, persistent diagrams, and a tabular summary.
• Explicitly states the source as well WD-1a from the Kakkonda geothermal field.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
