LAR 12095,40: X-ray CT Scans of a Martian Shergottite Meteorite Chip

X-ray CT scans of a chip from Martian shergottite meteorite LAR 12095,40. The data was scanned by Scott Eckley at NASA's Johnson Space Center on 3 January 2020 with a voxel size of 8.57 µm. The dataset is hosted by the Texas Data Repository and was last updated in March 2024.

Use Cases

• Analyze internal mineralogy and texture of a Martian meteorite based on the 3D X-ray CT scans.
• Study shock features and vesicle distribution within the shergottite sample based on the volumetric data.
• Perform non-destructive 3D segmentation of phases within the meteorite chip based on the high-resolution scans.
• Use as a reference dataset for comparing terrestrial and extraterrestrial rock microstructures.

Strengths

• Scanned at NASA's Johnson Space Center, indicating a high-quality acquisition environment.
• Specific voxel size of 8.57 µm is documented, providing a known spatial resolution.
• Exact scan date of 3 January 2020 is recorded.

Limitations

• Description metadata is limited; actual data quality, file formats, and size require manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
