Název v původním jazyce

Is there a Relationship between Magmatic Fabrics and Brittle Fiactures in Plutons? A View Based on Structural Analysis, Anisotropy of Magnetic Susceptibility and Thermo-mechanical Modelling of the Tanvald Pluton (Bohemian Massif)

Popis výsledku v původním jazyce

The present study focuses on the thermal and mechanical aspects of cooling of plutonic systems with respect to their internal structure. An analysis of the Tanvald pluton and the nearby Liberec granite (Krkonoše-Jizera Plutonic Complex, Bohemian Massif)using the anisotropy of magnetic susceptibility (AMS) method indicates that decoupled magnetic fabrics in these two plutons recorded increments of regional tectonic strain and strain during internal processes along a magma chamber boundary, respectively.Two regional sets of vertical fractures cut across the plutons and their host rocks. They are interpreted to have formed form as opening mode fractures (joints) after emplacement and cooling. Our thermo-mechanical finite element modelling indicates thatthe thermal stresses within the Tanvald pluton were compressive and fracture criteria were not met during pluton cooling.
