The mineral deposits of the Balkan Peninsula and western Turkey are bound to modern fold belts such as the Carpathians, Dinarides, Balkanides, Hellenides, and Pontides separated by large intermountain basins, e.g., the Pannonian Basin and bordering small basement structures such as the Dobrudja Zone. In view of the vast outcrops of Mesozoic and Cenozoic rocks, unsurprisingly, the majority of mineral deposits are found in Cretaceous, Paleogene, and Neogene rocks. This SE European mineral province is known for its porphyry-type and epithermal silver and gold deposits, e.g., Rosia Montana, Romania, Bor, Serbia, Chelopech, Bulgaria, and Kisladag, Turkey. The metallogenic districts are also host to Pb-Cu-Zn deposits. Additionally, Fe-Mn- and bauxite deposits are still mined. This Special Issue is open for new ideas and models created for these classical ore deposits. First and foremost it will be a forum for research on mineral deposits irrespective of their economic importance as a deposit under exploitation for quite a long period of time or as a newly discovered site in the state of a mining project, such as the lithium-boron mineralization in the Jadar Basin, Serbia. Even if some of the non-metallic mineral assemblages in sedimentary and igneous host rocks have not yet come under the spotlight of mining engineers and entrepreneurs they may be suitable targets for new genetic models and element concentrations hitherto not known from such lithologies. The following keywords should give an idea of the topics of interest for this Special Issue in view of the current and future technologies is given below:

• Clay minerals,
• Sand and placers,
• REE-U-Th mineralization,
• Nb-Ta- Ge-In-Ga-Se concentrations,
• PGE mineralization.

Unconventional resources in uncommon environments should be the central theme of this volume. New ideas may be presented as a review or a research paper.
