Abstract

This article presents the results of preliminary mineralogical characterization of scapolite from a new for Bulgaria locality – Mishevsko, Central Rhodopes. The examined samples exhibit a characteristic yellow luminescence under long-wave ultraviolet light. There are compositional variations, primarily affecting the extra-framework cation and anion species in the structure of the studied mineral and thus also the meionite component (62 < Me <74). At the end, considerations on the factors controlling the scapolitization process, as well as speculations on possible causes of scapolite fluorescence are presented.
