(ABSTRACT)
Close relationships between geodynamic evolution and magmatism at convergent plate margins are recognized in many modern and ancient orogenic areas. The East Carpathians area is a good example in which to consider the link between magmatism and geodynamics, as a complex spectrum of geologic processes (subduction, collision and extension) occurred in this region during Neogene-Quaternary times. The variations in the kinematics of the Intracarpathian blocks, representing the upper plate, were responsible for the specific geochemical features and evolution of various kinds of magmas (calc-alkaline or alkaline).
Key-words: Neogene-Quaternary, volcanism, Calimani-Gurghiu-Harghita mountains,
