Welcome to Andrea Regina Biedermann's Research Page
I have been fascinated by minerals and rocks for as long as I can remember. When I was a little girl, I smuggled tons of them into my dad’s backpack during family hikes. A few years later, and after having studied geophysics, I am now privileged to work with minerals or rocks on a daily basis – be it during field work or in the lab. My research focuses on
- How magnetic anisotropy in single crystals is related to crystal structure and chemical composition
- The relationship between mineral and magnetic fabrics in rocks
- The effects anisotropy has on the direction and intensity of remanent magnetization, or the shape and amplitude of magnetic anomalies
- How we can use magnetic anisotropy to investigate pore fabrics and preferred flow directions
This knowledge can be used to interpret magnetic anisotropy in terms of geologic processes or rock texture, to infer preferred flow directions, and for a more reliable interpretation of paleomagnetic directions and magnetic anomalies.
