The Kratovo-Zletovo volcano-intrusive complex which occupies an area of 1200 km^2 has many specific features which are unique in the Balkan Peninsula and further afield. Intrusive, subvolcanic, volcanic and volcano-sedimentary facies were determined in it. It is calc-alkaline magmatism with well developed series in which dacite-andesite prevail. Its age was determined as Oligo-Miocene (16 to 32 m.y.) to Pliocene. Important deposits and occurrences of metals, non-metals and energy raw materials are related to this volcanic complex. It is characterized by the complex caldera structure.
