Sažetak
As part of continuous sequence of Cretaceous limestones and dolomites, in the central part of Vis Island, quartz sand deposits are found. “Quartz sands” locally called vora, represent a solid or a friable material composed dominantly of quartz and some chalcedony. These sand deposits, developed as two separate beds, 1-6 meters thick, have been mined since the beginning of the 19th century because of the characteristic white color and were used for glass production by the famous glass factory in Murano. Numerous evidences of mining activities can be found north of Kostrina village (Veliki rudnik mine, Mali rudnik mine, Špilja od Vore cave, Tor rudnik mine). These mines represent combination of underground constructions, mines and natural karst caves (e.g. Veliki rudnik mine, Špilja od Vore Cave). During speleological and biospeleological investigations of these objects interesting endemic fauna was found, same as bat colonies. This further emphasized their uniqueness, and, in addition, Špilja od Vore cave represents cave type locality of Croatian fauna. Vora mines are an exceptionally interesting part of Croatian, Dinaric, but also Mediterranean geoheritage and they should be properly preserved. With proper and viable care, in the future they can be represented as a cave/mine park and thus can be used for the natural and cultural promotion, educational purposes and tourism activities.
