Dr. Marieke Rempe

My research interests lie in fault-zone and earthquake processes. Using a combined approach of laboratory experiments, microstructural analysis, field experiments and mapping, and numerical modelling, I study the physical properties and microstructural characteristics of rocks that experienced brittle deformation and subsequent hydrothermal alteration as well as the frictional behaviour of rocks to understand the processes and their kinetics active in fault zones throughout the seismic cycle.

Writing a report
LV-Nr. 176106

In this course you will be introduced to typical geoscientific text types and their outline. We will explore writing strategies and deepen geoscientific knowledge through writing. You will also learn how to use Microsoft Word professionally and get to know the basics of data processing and visualization with Microsoft Excel. One focus of the course is literature research and formally correct scientific citing, for which we will use a literature management program.

Geoscientific pratical: rock physics
LV-Nr. 176501

In this part of the laboratory practical, which comprises three experiments, rock and mineral samples are characterized using standard methods of experimental rock physics. The experiments include the determination of the volume properties total and matrix density as well as total and connected porosity, the determination of the transport property permeability and the complementary determination of basic properties of water (density and dynamic viscosity).

Rock Physics
LV-Nr. 177053

  1. Introduction to rocks and minerals
  2. Porosity and interface phenomena
  3. Hydraulic transport in rocks (Darcy's law, permeability models)
  4. Elasticity (stress, strain, Hooke's law, averaging schemes)
  5. Failure of rocks (fracture and friction)

In a laboratory practical, students independently conduct simple experiments to determine basic physical properties of rocks and fluids.
