Scientific focus (keywords): Late Cretaceous-Paleogene; igenous petrology; ore mineralogy; banatite; skarns; mineralogical exhibitions; Gold Museum; medieval monuments

Ever since the times of Bernhard von Cotta (19th century), the northern part of Apuseni Mts. and the south-western rim of the South Carpathians have been classical areas for the study of thermal metamorphic and metasomatic rocks related to Late Cretaceous-Paleogene magmatites ("banatites"). Skarn occurrences and related mineralization account for most of the significant mineral occurrences in the region, and hence, it is the intention of this trip to observe such outcrops that will be of interest for both igneous petrologists and ore mineralogists. Many of the areas to be visited represent type localities for severeal mineral species, especially Bi sulphosalts and borates. The trip will focus upon the banatite-skarn deposit occurrences at Băiţa Bihor (calcic and magnesian skarns with Bi-Cu ± Pb, Zn, W mineralization), Măgureaua Vaţei - Cornet Hill (high temperature skarns with gehlenite, tilleyite, spurrite), Ocna de Fier (magnesian skarns with Fe-Pb-Zn-Bi mineralization), Oraviţa-Ciclova (alkaline banatites, calcic skarns with Cu-Mo-Bi±W mineralization). Cultural stops will include historical sites in Haţeg area (Densuş, Sântămăria Orlea churches) as well as local mineral collections such as the Gold Museum in Brad and Gruescu private mineral collection in Ocna de Fier.
