R.W. Dalrymple is a clastic sedimentologist with wide-ranging interests. Ongoing research projects include: the sedimentology and high-resolution seismic stratigraphy of the tide-dominated, Fly River delta, Papua New Guinea; the sedimentology, sequence stratigraphy, and chemostratigraphy of Neoproterozoic and early Cambrian strata of the Mackenzie and Wernecke Mtns, N.W.T. and Yukon; the influence of physical sedimentary processes and biological controls on the textures, facies, and stratigraphy of bioclastic carbonates in the Oligo-Miocene, Te Kuiti Group, New Zealand; and the sedimentology and stratigraphy of transgressive, wave-influenced (dominated?) tidal flats, South Korea.
These projects are linked by three interrelated, long-term objectives: 1) to increase our understanding of tide-dominated depositional systems, which are less thoroughly studied and inherently more complex than wave-dominated systems, due to the development of mutually- evasive channel-bar complexes; 2) to document the influence of relative sea-level rise and transgression on the nature of the stratigraphic record, with particular emphasis on incised-valley systems and the proposed link between tide-dominated sedimentation and transgressions; and 3) to understand physical sedimentation in settings with "boundary conditions" that differ from those typifying Phanerozoic siliciclastics (i.e., Proterozoic siliciclastics and Phanerozoic, bioclastic carbonates). In the former case, the lack of metazoans and terrestrial plants creates a "non- actualistic" situation that is not mimicked anywhere in the modern world. In the second case, the sedimentary particles are produced in situ and thus are not transported to the depositional site from an external source. By examining how these changes in fundamental conditions influence the resulting deposits, the nature of the physical environments will be understood more fully.
Research opportunities for students (M.Sc. and Ph.D.) include projects on tide-dominated carbonate grainstones in the Miocene of southern France, Proterozoic fluvial strata in the Thelon Basin, Northwestern Territories, and subsurface studies in the Western Canada Sedimentary Basin, using core and industry well-log data. Dr. Dalrymple is also involved with the new School of Environmental Studies at Queen's University and would be interested in supervising students involved in interdisciplinary environmental projects, both in the local bioregion and elsewhere.
