Mineralpedia Details for Pretulite
Pretulite
Named after the Pretu Mountain, or Pretualpe, in Austria where the mineral was first discovered. Pretulite is a rare mineral that forms in lazulite-quartz veins in phyllite-mica schist at its type locality in Austria at the Höllkogel Mountains. Pretulite may have additional localities in the Czech Republic, France, and Norway, according to mindat. Pretulite will weakly fluoresce an orange color under short-wave ultraviolet light and produces a bright blue cathodoluminesence.
