> Dear all,
>
> I am looking for a postdoctoral researcher to participate in a four-year
> research project titled “What controls deformation in a 'bent' 3D orogen?
> The effects of spatially variable rock strength, erosion and mass transport
> on the tectonics of the Bolivian Andes�, which is funded by the Academy of
> Finland. The project will use fully 3D mechanical and thermomechanical
> numerical models to assess the relative influences of climate-modulated
> surface erosion, basal detachment strength and 3D deformation on the width
> of the fold-and-thrust belt in the eastern Bolivian Andes (a more detailed
> project description is provided below). The researcher will be hosted in
> the Department of Geosciences and Geography at the University of Helsinki,
> Finland and actively collaborate with project partners at the University of
> Pittsburgh, USA and University of Bergen, Norway.
>
> Candidates with an interest in numerical modelling of geodynamic, tectonic
> and/or surface processes are asked to send (1) a complete C.V. with
> publication citation information, (2) a 1-2 page letter of research
> interests and motivation for applying for this position, and (3) contact
> information for three people familiar with their doctoral research along
> with any questions to Asst. Prof. David Whipp (david.whipp en helsinki.fi).
> The project is scheduled to begin September 1, 2014 and the candidate must
> have received a doctoral degree in geology or geophysics by that time.
> Additional detail about the position can be found at
> https://wiki.helsinki.fi/display/HUGG/Opportunities.

> Project description:
> This project addresses the question what controls the width of a 3D
> orocline with along-strike variations in climate and rock strength? The
> study focuses on the eastern margin of the Bolivian orocline region in the
> Andes, where the orientation of the mountain front and major tectonic
> structures rotate ~50° from northern Bolivia to southern Bolivia, and the
> width of the orogen east of the Andean plateau doubles. These changes are
> coincident with a large decrease in regional precipitation and an increase
> in the thickness of weak rock layers that underlie the actively deforming
> Subandean fold-and-thrust belt, suggesting they may control the mountain
> belt width. Furthermore, this region is thought to experience
> orogen-parallel mass transport away from the orocline core as a result of
> 3D oblique convergence within the orocline, which may also affect orogen
> width.
>
> The project will use fully 3D numerical geodynamic models of generic
> oroclines to determine the relative influences of climate-modulated
> erosion, variable rock strength and 3D deformation on the along-strike
> width of an orogen. Results will be integrated with available field
> observations, remote sensing data and 3D tectonic reconstructions, and
> applied to interpret the recent history of the Bolivian orocline region of
> the Andes. The postdoctoral researcher trained in this project will conduct
> the numerical experiments and travel to actively collaborate with project
> partners at the University of Pittsburgh, USA and University of Bergen,
> Norway.
