The Kožuf volcanic massif is disposed in the frame of the Vardar zone. The volcanic and volcano-sedimentary rocks from the “complex of Pliocene sediments and pyroclasts” overlay the metamorphic (Precambrian and Paleozoic) and sedimentary (Triassic to Upper Eocene) rocks of the region (Jankovic et al. 1997; Boev & Jelenkovic, 2012). The Pliocene volcanic and volcano-sedimentary rocks occur as layers in a lacustrin basin and subvolcanic bodies crosscutting the older rocks (Triassic carbonates; Percial, Radke, 1994; Boev & Jelenkovic, 2012). The Pliocene volcanism is strongly explosive and predominating volcanic rocks are volcaniclastic (pyroclastic tuffs and breccias and epiclastic conglomerates). The radiogenic age (K-Ar method) determinations of the volcanic rocks are between 6.5 and 1.8 Ma (Boev et al., 1992). Volcanic rocks are represented by shoshonites, latites, quarz latites, dacites, trachytes, and rhyolites.
