Experimental Data on Basalt Creep During Carbonation from CarbFix, Iceland

CarbFix site in Iceland provides the basaltic rock samples for this experimental dataset. The data was collected by Tiange Xing of MIT from load stepping creep experiments under various pore fluid conditions at approximately 80°C and 50 MPa effective pressure. It includes mechanical, acoustic, and pore fluid chemistry measurements to study time-dependent deformation for geological carbon storage.

Use Cases

• Modeling time-dependent creep deformation in basalts based on the described mechanical and acoustic data.
• Analyzing the effect of fluid saturation (dry, H2O, H2O+CO2) on sub-critical cracking based on acoustic emissions data.
• Calibrating empirical creep models (log-time or power law) using the stress-dependent fitting parameters mentioned in the description.
• Studying the role of aqueous fluids in brittle creep processes for carbon mineralization security assessments.

Strengths

• Data originates from a real-world carbon sequestration project site (CarbFix, Iceland).
• Experiments were conducted under controlled, high-pressure and high-temperature conditions relevant to subsurface storage.
• Multiple data modalities were collected, including mechanical, acoustic, and fluid chemistry, as described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
