Dinarido-Albanido-Hellenic folded alpine belt is interpreted as a result of Mesozoic - Cenozoic convergence and continental collision of a series of micro-blocks localized between the Eurasian and African plates. The ophiolites of the Balkan Peninsula are particularly formed in the ocean basins wh ich were divided by micro-continents during the Mesozoic period and they are products of the Mesozoic - Cenozoic obduction. The Vardar Ophiolites from the region of Gjilan are covered by a chaotic sequence, well stratifi...

THE STRUCTURE OF THE GEOLOGICAL TIME FROM THE PERSPECTIVE OF THE REAL DYNAMIC CYCLES OF THE EARTH

(Stef92 Technology, 2011-06-20, Mircea Ticleanu)

Show more

Every cyclic geological phenomenon may sugge st a structural image of the geological time. The dynamic cycles with very long periods can characterize the whole geological time, but especially the Precambrian. The cy cles with periods between 4 and 26 Ma are useful for the temporal individualization of th e Phanerozoic and the cycles with a short periods are very representative for Cenozoic. But the Earth’s geological history also provides a good perspective over the cosmic time through a super-mega-cycle (~2.56 ...
