The Romanian coasts can be divided in two categories: erosion coasts (cliff shores) and accumulative coasts (barrier beaches). The activ e behavior of the cliffs is due to the action of marine abrasion and slope processes, landslides and gravitational collapses. Cliff shores between Cape Midia and Vama Veche has a complex lithological profile. Silt and clay particles are carried seaward by the rip cu rrents system, while sand and gravel particles are conveyed along the coast. Textural and mineralogical study of th...

The Dardanian zone (Serbian-Macedonian massif) represents the western part of the Rhodope crystalline basement.

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...

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 ...
