Mineral Identification from Field Observations

Task

Each case gives observed physical properties (never the chemical formula — that would give the answer away) and asks for the species name only, one lowercase word. The reference document is a 98-species property handbook so retrieval-augmented runs can match observations against catalog entries; closed-book runs must recall the species from the properties alone.

Scoring

The judge normalizes the answer and reference species name (lowercasing, stripping punctuation, and collapsing known synonyms and transliterations such as creedite/credit, stibnite/antimonite, labradorite/labrador) and requires an exact match. One point per correct species, accuracy over all cases.
