X-ray CT Scans of the Murchison Meteorite at 9.49 μm Resolution

X-ray CT scans of two chips from the CM2 Murchison chondrite meteorite. The data consists of 1229 slices with a voxel size of 9.49 μm in all dimensions, scanned by The University of Texas High-Resolution X-ray CT Facility in February 2016. The dataset was created for Dr. Romy Hanna and is supported by NASA grant NNX13AO64H.

Use Cases

• Analyze the three-dimensional internal structure of a carbonaceous chondrite meteorite based on the high-resolution CT slices.
• Segment and quantify mineral phases and porosity within the meteorite samples based on the volumetric CT data.
• Create digital models for finite element analysis of material properties based on the reconstructed 3D volume.
• Compare the morphology and texture of different chips from the same meteorite specimen based on the two scanned subsamples.

Strengths

• High-resolution volumetric data with a consistent voxel size of 9.49 μm in X, Y, and Z dimensions.
• Contains 1229 individual CT slices, providing detailed internal cross-sections.
• Scanned at a specialized facility (UTCT) with clear provenance and acknowledgment requirements.
• Specific scan date (25 February 2016) and associated NASA grant (NNX13AO64H) are documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain ML tasks.
• The dataset appears to be a single, static scan from 2016, with no indication of temporal series or updates.
