3D X-ray Tomography Scans of Magmatic Mush Analog Particle Geometries

A set of 3D X-ray tomography datasets showing particle bead packs developed as magmatic mush analogues. Each dataset contains a stack of TIFF images depicting cuboid, rod, disc/plate, irregular, and mixed particle shapes. The data were collected on a Nikon XCT scanner to measure packing geometries, contact areas, pore volumes, and surface areas.

Use Cases

• Measure packing geometries and contact areas from 3D scans of cuboid, rod, and disc/plate particles.
• Calculate pore volumes, surface areas, and connectivity for permeability simulation in bead packing models.
• Develop advanced porosity-permeability relationships using scan data of irregular and mixed particle shapes.
• Validate finite element or discrete element models of complex packed beds with the provided 3D tomography data.

Strengths

• Data includes multiple distinct particle geometries: cuboid, rod, disc/plate, irregular, and mixtures.
• Each scan is accompanied by a settings file detailing exact imaging conditions like x-ray energy and resolution.
• Data was collected using a Nikon XCT scanner, a standard instrument for high-resolution tomography.

Limitations

• Specific quantitative metrics like total number of scans, image resolution, or dataset size are not provided.
• The dataset focuses on laboratory analogue systems, not direct in-situ measurements of natural magmatic mushes.
