Dr. Cees-Jan De Hoog

Senior Lecturer, Ion Microprobe Facility staff

Biography

Background

I am a geochemist and petrologist working on volatile cycles in subduction zones and mantle processes. I mostly use micro-analytical techniques to study rocks in situ at the micrometre scale.

Qualifications

PhD 2001

Responsibilities & affiliations

Member of Mineralogical Society

 

Undergraduate teaching

Earth Dynamics (lecturer and course organiser)

Global Tectonics and the Rock Cycle (lecturer)

Inchnadamph Field Training

Open to PhD supervision enquiries?

Yes

Areas of interest for supervision

Research areas: metamorphic and igneous processes, subduction zones, volatiles, melt inclusions, geochemistry

Current PhD students supervised

Ben Harris (PhD project: The role of phengite in the volatile cycle in subduction zones)

Xinkai He (MRes project: Rare earth elements in olivine)

Past PhD students supervised

Eleri Clarke (PhD 2020: Squeezing the sponge: the role of serpentinites in subduction zones)

Research summary

Behaviour of volatiles and fluid-mobile elements in subduction zones, geochemistry and petrology of mafic and ultramafic (metamorphic) rocks, trace-element partitioning between minerals, mantle petrology and geothermobarometry, volcanology and igneous petrology, in-situ analytical techniques (SIMS and ICP-MS)

Current research interests

- Behaviour of volatiles and fluid-mobile elements during dehydration of subducting serpentinites. Collaborative project with K. Hattori (University of Ottawa), Jason Harvey (Leeds), Ivan Savov (Leeds), Ralf Halama (Keele) - Trace element geochemistry of olivine from mantle rocks: applications to geothermobarometry and mantle petrogenesis. This project is now extended to olivine inclusions in diamonds (collaboration with Thomas Stachel, University of Alberta). - Formation and evolution of cratonic roots - distinguishing metasomatic imprint from primary mantle signatures. Case studies from Kaalvallei and Kirkland Lake xenolith suites. Collaborative project with Dan Schulze (University of Toronto).

Past research interests

- Petrogenesis of ultrahigh-pressure eclogites and garnet peridotites from the Pohorje Mountains, Eastern Alps (NE Slovenia). Collaborative project with Marian Janak (Slovak Academia of Science, Bratislava), Mirijam Vrabec (University of Ljubljana), Niko Froitzheim (University of Bonn) - Into the subduction channel : petrological, geochemical and thermomechanical constraints on subduction processes and plate-slab coupling. Project in Zermat-Saas unit, Western Alps, and the Sistan melange, Iran. Collaborative project with Phillipe Agard and Samual Angiboust (University Paris 6) and Mike Searle, Dave Waters, Tony Watts (Oxford University). Partially funded by the British Council (2009-2010)
