| Species: | Opal |
| Formula: | SiO2 · nH2O |
| Formation: | Secondary |
| Comments: | Opal in the variety of "hyalite" occurs as colorless thin bubbly patches on seam surfaces, formed on the underside of horizontal seams in the rock. It frequently coats stains and coatings of green to black secondary phosphates (mitridatite, rockbridgeite) which show through the colorless opal. |
| Luminescent properties: | Mildly fluorescent yellow SW UV. Unlike the vividly yellow fluorescence of richer hyalite well known from the Spruce Pine pegmatites, Mitchell County, NC. The difference is in the extent of uranium salts - present but diminutive at Foote but much richer in the Spruce Pine pegmatites. |
| Quality for species: | Poor for species, only of interest for locality collectors. (#) |
| Abundance at site: | Rare |
