Tertiary period – lasted about 63 mLN. years (65 & 2 ± 0.2 mln.). In Macedonia is represented by paleogenic and neogenic sedimentary and volcanic rocks. Paleogen is widely developed with eocene-oligocene sedimentary masses with a thickness of up to 3,500 m in the Tikvesh and Ovchepolic valley, and with smaller masses in the Delceva valley and Valandovo and Gevgelija. In all areas, paleontologically is documented with fossil snails, shells, nuculites, and more. The eocene is developed with basal conglomerates and flawed sediments, and the oligocene is mainly carbonate. During Goren Oligocene, strong volcanic activity (Zletovo Kocani, Bucim Borov, Delcevo) took place. Neogene is represented by medium and upper miocene and presented mainly with gliedolarotic and aluver-sandy sediments with coal layers in Upper Miocene, and in Pliocene mostly with jackals and sands. They were developed in all Macedonian valleys, with the greatest obesity to reach Skopje (2,200 m), Tikvesh, Strumica and Pelagonia valley (up to 1,000 m). Vulcanism was active mainly in the Miocanovo in Kumanovo, Probistip-Kocani, and in Mariovo and at the beginning of Pliocene. Lit.: T. Rakkavic, N. Domurjanov, P.
