Samples from four distinct locations: Brandur (Iceland), Avellino (Italy), K?lauea Iki (Hawaii, USA), and Saint Kitts (St. Kitts and Nevis). The dataset comprises X-ray tomography image stacks with spatial resolutions from 3.5 to 56 µm, label files, and vector matrices for permeability simulations. It also includes electron microprobe analyses of plagioclase and amphibole minerals from Saint Kitts, and was last updated on 2026-04-09.
Use Cases
- Conduct 3D permeability simulations based on velocity and pressure field vector matrices.
- Analyze mineral composition based on electron microprobe analyses of plagioclase and amphibole.
- Study rock microstructure and connectivity using X-ray tomography image stacks and binary images of connected matrices.
- Validate geological models using detailed 3D representations of igneous samples from multiple volcanic sites.
Strengths
- X-ray tomography images have spatial resolutions ranging from 3.5 to 56 µm.
- Data includes samples from four distinct geographic locations, providing variety.
- Dataset is organized with dedicated folders containing image stacks, label files, vector matrices, and metadata.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file sizes are unknown, which may limit suitability assessment.
