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 seeking a graduate student to investigate the Moncton and Sackville basins of southern New Brunswick. These Mississippian-Pennsylvanian basins contain a combination of clastic sedimentary rocks and evaporites. They display the effects of strike-slip deformation and evaporite movement    resulting from the final stages in the assembly of the supercontinent Pangea. The project will involve a combination of field and subsurface data including seismic profiles collected in the course of exploration for oil and natural gas.
  • 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 current 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.
  •  In 2014 I will be seeking a student to work on the sedimentary and tectonic record of the early stages of thrusting in the Canadian Cordillera of Alberta.  This project would involve examination of Jurassic sedimentary successions and their relationship to mappable thrust faults in the Front Ranges and/or Main Ranges in Alberta.
