Application of multivariate statistical methods for analysis of thermomechanical numerical models of diapirism Most of the thermo-mechanical processes, that are associated with the geodynamic evolution of the lithosphere, can be derived from the laws of conservation of mass, momentum and energy in a continuous conception of space. The study of such dynamical systems reveals their strong sensitivity to variation of the initial conditions. For testing the applicability of multivariate statistics in analyzing the influence of the initial conditions, two independent 2D thermo-mechanical multilayer numerical models of crustal diapirism of the Moldanubiam zone were created. The diapirism in central part of Moldanubian zone is characterized by exhumation of HP-HT granulites during the Variscan orogeny (Lexa et al., 2011) which is influenced by density contrast of the middle mafic and lower felsic crust, the ratio of the amount mafic and felsic material, radiogenic heat productivity of the felsic lower crust and shape of the interface of this two layers. The initial setup of this models reflects the situation in future central part of the Bohemian Massif after subduction of the Saxothuringian continental crust and after redistribution of felsic material beneath a base of a lower-crustal area of the...
