Analog modeling of subduction zone processes
Tkáčiková, Tatiana ; Žák, Jiří (advisor) ; Krýza, Ondřej (referee)
Subduction zones, domains where oceanic lithosphere is subducted into the mantle beneath an overriding plate, are one of the most dynamic tectonic environments. A wide range of the long-lasting subduction-zone processes may be suitably reproduced and studied through analog modeling and thus may be directly observed in laboratory, though at time and length scales that differ fundamentally from nature. The main goals of this Bachelor thesis are first to provide an overview of large-scale architecture of subduction zones, to present an overview of the published analog experimental methods, and then to discuss the main outcomes of analog modeling of subduction zones and accretionary prisms. The thesis also summarizes the main mechanical parameters of materials used in the analog modeling. Furthermore, a set of simple experiments were performed, with the main goal to model formation of basalt-bearing mélanges during subduction of seamounts and volcanic belts that may occur on ocean floor and are commonly incorporated into accretionary wedges as dismembered Ocean Plate Stratigraphy (OPS).

Analogue and numerical simulations of the geodynamical systems - insights from the models of the Earth collision tectonics and Martian mudflows
Krýza, Ondřej
Analogue and numerical modelling in geosciences is an excellent tool for studying complex spatio-temporal relationships in mass and energy transfer. Recent developments and advances in the plate tectonics and planetology require a combination of both approaches to simulate processes that cannot be studied directly in-situ. Advanced physical models are complemented by deformation analysis which is based on image velocimetry and photogrammetry, while numerical simulations utilize both modern and traditional methods to solve corresponding equations in complex domains. This work compiles several models that are focused on deformation analysis associated with material and heat transfer in large accretionary systems. The second subject of the thesis represent the investigation of the formation and propagation of large mudflows in martian atmospheric conditions. In the first part of the work we present a general overview of the problems of analogue and numerical modelling including scaling theory, governing equations, individual methods and history. In the second part of the thesis we deal with laboratory and numerical simulations of collision-indentation tectonics associated with the emergence of large accretionary systems on Earth. The last part of the thesis is devoted to experiments designed for the...
