Photo: Phosphates in the Cioclovina Cave (RO) This field trip is designed as an en-route experience starting from Cluj towards the west and then to the south to the Cioclovina Cave. One of the key-sites to visit is the Vântului Cave (Wind Cave, Şuncuiuş, Bihor county), the most extensive karst system in Romania >50 km in length, where a number of mineralogical, geomicrobiological, and speleothem investigations have been carried out over the last 15 years. The cave is famous for its gypsum deposits and REE-rich manganese and iron coatings. The nearby Bolhac (Ungurului) Cave, hosts among other interesting minerals a potentially new mineral species, which is currently under description.

Urşilor Cave (Bears' Cave) at Chişcău (Bihor county) and Scărişoara Ice Cave at Gârda (Alba county) will give participants the opportunity to admire Romania's most beautiful touristic cave and the world's 2nd largest ice block in a cave (100,000 m3), respectively.

A large part of the trip will focus on the mineralogy of Cioclovina Cave (Şureanu Mountains, near the city of Hunedoara), from which over 25 minerals were described so far. Among them, rare occurrences of high-temperature minerals (berlinite, ellestadite-(OH)) along with a large number of common (brushite, monetite, crandallite etc.) and "exotic" (churchite-(Y), foggite. etc.) phosphate minerals.
