Geodynamics
is the science of understanding and modeling physical processes
occurring within the Earth. The model results are compared with
geological and geophysical observations in order to improve our
understanding of the dynamical system, to determine which processes and
mechanisms are important in the Earth, and also to constrain relevant
physical parameters. The geophysics group at Uppsala University has a
long history of studying the Baltic Shield and the Caledonide mountain
belt at its western boundary.Of particular interest are the thick
sequences of nappes that characterize the Caledonides and which indicate
horizontal transport over several hundreds of kilometers. Some of this
transport may have been accommodated by underlying, mechanically soft,
carbon-rich shales. However, it has been hypothesized that horizontal
extrusion of hot, low-viscosity crust may have played the dominant role
in this process. Further important clues about the Caledonian
collision are provided by widespread observations of high-grade
metamorphism in the basement beneath the thrust sheets, which suggest
burial to depths greater than 150 km. Similar observations have been
made in the presently active Himalayan orogen, and it has been proposed
that the two orogens are dynamically analogous. The advantage of
studying the Caledonian orogen is that the deeper crustal layers, which
can only be imaged indirectly in the Himalayas, are exposed at the
surface or are accessible via deep drilling (see http://www.sddp.se).
Another scientific aspect is the relation of the remnants of the
ancient Caledonian orogeny to the present-day topography and possible
uplift throughout Norway. The great variability along the Scandes
mountains in terms of elevation and degree and depth of isostatic
compensation have long confounded scientists, and it is possible that
the answer lies in the much older Caledonian tectonics.
Project description:
The PhD candidate will perform research within the field of geodynamic
modeling related to any (or a combination) of the above-mentioned
research topics with focus on orogenic processes. It is of particular
interest to model the Paleozoic Caledonide collision and couple the
results to geological and geophysical data. Comparisons of the fossil
Caledonide mountain belt with active mountain belts through modeling can
be part of the research. Existing modeling codes may be used, but
further algorithm development may also be required. The PhD candidate
will work within a larger research program with other candidates and
researchers from Sweden and abroad.
Qualifications:
We are seeking a motivated candidate with a strong interest in research
who has an academic magister/master- or engineering degree, or
equivalent, in geophysics, physics, earth sciences or a similar field
(formally, four years of university study including a minimum of 1 year
at advanced level are required). Linux/Unix skills are necessary,
experience in programming is desirable, and knowledge of software such
as GMT, shell scripts and modeling codes is a merit. The successful
applicant is expected to, and should be willing, to spend time in the
field, as part of her/his PhD studies. Good oral and written proficiency
in English is required.
The position is full-time for four
years and may include up to 20% of research or teaching assistantship. A
stipend may be paid out the first year and the following 3 years
consist as a regular employee at the university. To be appointed as a
PhD student it is required that the candidate has been admitted, or
will be admitted, to a PhD education program, in which the ability to
benefit from the PhD education is crucial. Uppsala University is an
equal opportunity employer and encourages women to apply for
positions.General regulations for PhD studies can be found in
Högskoleförordningen 5 kap §§1-7 as well as in the university's rules
and regulations http://regler.uu.se/.
