Quartz-mica schist and gneiss hosted clay deposits within the Yenipazar (Yozgat, Central Anatolia) volcanogenic massive sulfide ore

The Yenipazar deposit of volcanogenic sulfide occurrence, situated approximately 9 km SW of Yenipazar, is hosted in quartzmuscovite schists and gneiss. Following the Late Cretaceous, the quartz-mica schists and gneiss have been altered to clay minerals, resulting in important kaolin deposits.
