Richard Callow M.Esc (Oxford), D.Phil (Oxford)

I arrived to work as a postdoc in the MUN Ichnology group in October 2009, after completing my graduate studies at the University of Oxford in the summer of 2009. I am working here on the ichnology of slope turbidite sequences as part of the Slopes 2 Consortium, a multi institution, industry-funded research team which is based at the University of Aberdeen and led by Prof. Ben Kneller

http://www.turbidites.org/projects/slopes/slopes.html. The aim of the Slopes 2 project is to combine seismic, modeling and outcrop studies to improve the understanding of slope systems, and develop rules for reservoir prediction in slope settings. My research with the Slopes group is focussed upon the ichnology of the Cretaceous age Rosario Formation of Baja California, and is conducted in collaboration with researchers and PhD students at the University of Aberdeen and the Colorado School of Mines.

The other members of the Slopes team are focussed upon the large-scale architecture and geometries of turbidite systems, such as large channel-levee systems of the Rosario Formation. The interest here at MUN is to use ichnology in these deep marine settings to improve facies characterization of fine-grained and heterolithic sediments, to apply deep-marine ichnology as a tool for detailed palaeoenvironmental analysis and to investigate the impacts of bioturbation on reservoir quality. The Rosario Formation provides an ideal natural laboratory to investigate these problems, being an exceptionally well exposed succession that has been mapped, logged and studied in great detail from a largely sedimentological standpoint and whose architecture and stratigraphic evolution are relatively well constrained. The ichnology of the Rosario Formation has received little attention, and initial field reconnaissance and studies (Oct-Nov 2009) have revealed great potential for the application of ichnology in this area. Further field seasons in the Rosario Formation are planned for April 2010 and October 2010.

Richard has now taken a second position in the group to study the shallow marine quartzites of the Bradore and Hawke Bay Formations of western Newfoundland with respect to their sedimentology, ichnology, and porosity/permeability characteristics.
