Аннотация:Abstract — The study of focal mechanisms in the southern Aegean sector of the Mediterranean mobile belt revealed that the stress-strain state and the orientation of its principal axes in the lithosphere vary both horizontally and vertically in a complicated manner. Such a distribution can be accounted for neither by a simple mechanical (collisional or subductional) interaction between convergent lithospheric plates nor by the effect of a floating-up and spreading mantle diapir. The present-day knowledge of this and some other parts of mobile
belts suggests that the observed pattern can be consistently interpreted solely in terms of a secondary increase in the volume (and primarily area) of certain slices of the layered cover or lithosphere, possibly due to additional mineral matter furnished by ascending flows of deep fluids. The stress-strain state calculated within the framework of a mechanical structural model of the region consistent with this hypothesis complies with the laws of mechanics.
