Thermal transport properties of minerals and rocks

Thermal transport properties are important physical properties to understand the driving forces in geodynamics. Furthermore, thermal transport properties are important for material science and the development of new technology. Nevertheless, only little is known about thermal transport properties of minerals and rocks. The focus of our experiments is the interrelation of elastic properties and thermal transport properties and their relation to crystal structure. The results are used for thermal modelling of crustal and mantle processes.

 

  • Thermal diffusity during a-b-quartz transition (DFG)
  • Radiative heat transport in rock-forming minerals (DFG)
  • The influence of order-disorder transition in feldspars on thermal transport properties (DFG)
  • Anisotropy of mantle minerals (PROCOPE, DFG)
  • Thermal transport properties during dehydration (GFZ)
  • Transport properties in polymer-magnetite materials


Thermal diffusivity of quartz as a function of temperature. The a-b-transition is clearly resolved as a minimum in thermal diffusivity.
