Data for: "X-PRISM: An Open-Source Spatial-Spectral Workflow for Automated Mineral Mapping from Micro-XRF"

This dataset contains the case-study mesoscale micro-XRF data used to demonstrate and evaluate X-PRISM, an open-source platform for spatially aware automated mineral mapping from micro-XRF data. The archive `xprism_case_study_data.zip` includes four raw Bruker BCF scan tiles from Cu-Mo skarn samples: `1-dl.bcf`, `1-dr.bcf`, `1-ul.bcf`, and `1-ur.bcf`. These files are provided as raw instrument data to support reproducible elemental-map generation, spectral inspection, grain-based annotation, model inference, and independent reprocessing with X-PRISM or compatible micro-XRF analysis tools. The dataset is intended to accompany the X-PRISM source-code repository and the associated manuscript. Users can read the BCF files directly in X-PRISM or convert them to NumPy arrays using the example script provided in the repository (`examples/read_bcf_to_numpy.py`). Instrument: Bruker M6 JETSTREAM micro-XRF spectrometer Spot Size: 50 μm Step size: 160 μm Dwell time: 15ms / pixel
