| Locality type: | Quarry | |
| Classification | ||
|---|---|---|
| Species: | Becquerelite | |
| Formula: | Ca(UO2)6O4(OH)6 · 8H2O | |
| Formation: | Secondary | |
| Comments: | Appears as sparse, somewhat earthy encrustations of miniscule, brownish-yellow crystals on more exposed and weathered surfaces. As with other uranium minerals, this is associated with the weathering of uraninite in the granite. Crystals are transparent and sufficiently small to give the impression of a pale colouration at moderate magnification (x45). | |
| Habit: | Indeterminate - semi-crustose. | |
| Colour: | brownish-yellow, appears very pale due to size of crystals. | |
| Luminescent properties: | Reacts under Long Wave UV: dim brownish orange | |
| Quality for species: | Poor for species, only of interest for locality collectors. (#) | |
| Abundance at site: | Rare | |
