SPELEOTECT - Active tectonics and recent dynamics of micro-displacements along major fault systems of the Eastern Alps registered in caves
Start: November/December 2013
Numerous field studies, seismic data, and GPS observations suggest ongoing activity along major tectonic fault systems in the Eastern Alps. This project uses caves in Austria as field laboratories to map displacements of cave passages, monitor micro-displacements and to date active faulting by applying the U-series disequilibrium method on damaged and sealed speleothems.
Key tasks comprise
- identifying, documenting and dating active faults in Austrian caves
- investigating the kinematics of active faults and reconstructing the (paleo)strain field
- discriminating between fault displacements caused by seismic slip or aseismic creep
- monitoring the recent dynamics of micro-displacements along single faults
- updating the paleoseismic data for the Eastern Alps
The PhD student will be mainly involved in mapping, sampling and sample preparation of damaged speleothems for U/ Th-dating, palaeostrain quantification on faults and in high-resolution microtectonic studies (SEM, CL, EMPA, EBSD) of faulted flowstones for discriminating between fault displacements caused by seismic slip or aseismic creep.
Applicants with a completed Master’s degree with basic knowledge in speleology (and the will and the physical ability to work in vertical Alpine caves), (micro)tectonics and/or high resolution analytical techniques (e.g. SEM, CL, EMPA, EBSD) are preferred. We are especially keen to promote the careers of women, and we therefore look forward to receiving applications from female candidates.
