Original use
Idrialite mineral is a polycyclic aromatic hydrocarbons and it was found in small quantities in the ore deposit. It occurred in the shape of impregnations, pores and geodes. The Idrija ore deposit is a typical location (locus typicus) for very rare, yellow-green Idrialite mineral, which was first described by Janda in 1892. Idrialite belongs among organic substances with the chemical composition C22H14. Rare crystals are small and visible only when magnified. It can be brown, yellow or green, in crust coatings, but more often it is massive, fine-grained or nodule-shaped. It is usually found with clay and some minerals of Idrija ore deposit, especially pyrite, cinnabar, flint and gypsum. The older name for Idrialite is Idrialine. When illuminated with ultraviolet light it fluoresces – glows in green or bluish light.
