Analogue modelling of geological processes
Monoaxial deformation apparatus
This convergence 3D box allows for the simulation of oblique indentation/collision in a crustal-scale or lithospheric domain with thermally controlled rheological stratification using paraffin wax and granular multilayers. The moving wall is equipped with two step motors that move each end of the moving wall separately, the moving wall adjusts its length depending on the angle of indentation.

Monoaxial deformation apparatus
This convergence box is used for experiments simulating the deformation of crustal-scale or lithospheric-scale deformation. The apparatus consists of large glass panes (140x80cm) confining the model domain, a basal heating plate, and top heating (an array of light bulbs) that maintain a stable heat gradient in the model. This setup is used with different types of paraffin wax.

Convergence box 2D including step motor and heating plate
Extension box - orthogonal
The analog apparatus allows us to simulate the development of a rift basin combined with progressive tilting of the basin flanks to identify structures and driving mechanisms characteristic for either gravity gliding or tectonic extension. Viscous silicone putty and mixtures of granular sand and cenospheres are used as analogs for salt and overburden sediments, respectively.

Monoaxial deformation apparatus
This is a classical monoaxial convergence sandbox suitable for modeling surface response of tectonically shortened basins with salt layers and salt diapirs. After the experiment is finished, the box allows the extrusion of the model domain and its slicing for 3D reconstruction.

Magma intrusion box
The experimental box comprises a 1.2 m long by 1.2 m wide by 0.5 m high open container with a 2 cm hole in the center of the base. An injector with a nozzle is inserted through the central hole and connected to a customized motor-driven syringe pump. The system allows the simulation of magma emplacement into shallow crust. We employ plaster of Paris as the analog of magma and granular materials (flour, sand) as the equivalents of the host solid rocks.

Sedimentation and liquefaction simulator
The experimental setup consists of a water tank positioned on a shaking table. Sedimentary systems (e.g. delta in river estuaries) are constructed by manually controlled sedimentation in various hydrodynamic environments. A blow of a mallet or a pendulum creates vibrations in the table separated from the frame by springs.
