Description :
The Pliocene-Quaternary evolution of slopes of the Armenian Highland is considered against the background of climatic changes and block tectonics. Most of the present-day slopes date back to the Late Pliocene or Early Pleistocene. During the Quaternary new slopes were formed as the highland due to volcanic processes, erosion of antecedent valleys and river piracy, glacial processes (slopes of cirques, troughs and morainic hills). Climatic change controlled the type and rate of slope processes, the defluction prevailed at early stages (Late Miocene-Pliocene) and became less intense later (in the Pleistocene and during historic time in particular) because of the increase in aridity. - (L'Ed.).
