LAR 12011,54: X-ray CT Scans of a Martian Shergottite Meteorite Chip

X-ray computed tomography scans of a chip from Martian shergottite meteorite LAR 12011,54. The data was scanned by Scott Eckley at NASA's Johnson Space Center on January 3, 2020, with a voxel size of 12.49 micrometers. The dataset is hosted by the Texas Data Repository and was last updated in March 2024.

Use Cases

• Analyze the internal 3D structure and porosity of the meteorite chip based on the X-ray CT scans.
• Segment and classify mineral phases within the sample based on density contrasts visible in the CT data.
• Create digital 3D models for visualization and non-destructive examination of the astromaterial.
• Conduct comparative petrological studies with other Martian meteorites based on the high-resolution volumetric data.

Strengths

• Scanned at NASA's Johnson Space Center Astromaterials X-ray Computed Tomography Lab, indicating a high-quality source.
• Specific scan date (January 3, 2020) and precise voxel size (12.49 µm) are documented.
• Explicit provenance linking the sample to the well-characterized Martian shergottite LAR 12011.

Limitations

• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• The dataset's total size, file formats, and exact data structure are unknown from the metadata.
• Row count is unknown, which may limit suitability assessment for certain computational tasks.
