Tectonics, Structural geology: Evolution of deformed sedimentary basins

Research interest

I am a structural and sedimentary geologist working on deformed sedimentary basins in orogens (mountain belts) in order to determine the tectonic processes that controlled both sedimentation and deformation. My projects typically involve a combination of fieldwork with geophysical and geochronological data where available. Much of my work has been focussed in the Appalachians and Caledonide orogens of eastern Canada and the British Isles, where sedimentary rocks and associated folds and faults provide a record of ocean closure and supercontinent assembly. 

Research opportunity
  • I am also seeking a graduate student to work on the early Paleozoic detrital zircon record of the Appalachian-Caledonide orogen in Atlantic Canada and the British Isles. Detrital zircon geochronology provides a powerful tool in recording the collision of terranes during orogenesis. In this case we seek to determine the timing and mechanism of closure of the Iapetus Ocean. This work will complement that of previous MSc. students H. Pothier and R.Dokken
  •  I am seeking a graduate student at Ph.D. level to work on salt expulsion structures in mainland Nova Scotia and Cape Breton Island. The map pattern of late Mississippian and Pennsylvanian strata strongly suggests development of salt-expulsion minibasins similar to those on modern continental margins, but formed in a tectonic environment involving strike-slip motion and basin inversion. This project would involve compilation of data from fieldwork, analysis of cores, and interpretation of seismic reflection profiles.
