Minerals Module

The minerals module ranks reflectance spectra against a library. It uses shape metrics including spectral angle, correlation, derivative correlation, and continuum-removed correlation.

from lux.modules.minerals import identify_mineral

result = identify_mineral(reflectance_spectrum, top_k=5)
for match in result.matches:
    print(match.name, match.score)

Important Limitation

C12880MA covers roughly 340-850 nm. Many definitive mineral features are in SWIR, Raman, XRF, or other modalities. The module returns hypotheses, not a legally defensible mineral assay.

Best Use

• iron oxide trends
• visible color/continuum classes
• local reference matching
• field triage before lab confirmation
