Tectonophysics

In our research, we are trying to understand mantle and lithospheric processes. Understanding the behaviour of plate boundaries is one of our prime research targets. Our approach is to combine quantitative studies (in particular: numerical simulations) with geological and geophysical observations.

Research

Tectonophysics (or lithospheric geodynamics) concentrates on trying to understand mantle and lithospheric processes that shape our planet. Although formally part of geophysics, Tectonophysics is a field right at the interface between geophysics and geology, and geophysics and geodesy. Our approach commonly is to combine quantitative study (numerical model simulations) with geological, geodetic and geophysical observations.

Teaching

Tectonophysics is mainly taught at the master’s level, but our group also contributes to smaller modules aimed at interested adults. If you are interested in studying Tectonophysics at Utrecht University, we recommend a bachelor’s degree in Earth Sciences with a minor in Physics. An alternative is that you first obtain a bachelor’s degree in Physics, preferentially with a minor in Geophysics.

GFLEX

GFLEX is a finite difference code for Earth scientific applications. It solves a flexure equation for small vertical deformations of a thin (Kirchhoff) plate, linear isotropic elasticity, and plane stress conditions. Plate thickness can vary within the two-dimensional Cartesian map domain. DOWNLOAD

The current version (1.1) has a number of limitations:

  • Clamped boundary conditions on all sides only
  • Uniform values only for restoring pressure, infilling loads, in-plane tractions, and elastic moduli
  • No faults
