2011-03-24 – SEMINAR by David Chew and Ian Sanders: High-pressure metamorphism in 475 Ma arc-continent collision in NW Ireland: can geological observations ground-truth the results of numerical modeling?

24 March, 2011 (13:00), 5 Merrion Square, Dublin 2.

Speaker: David Chew and Ian Sanders, Trinity College Dublin, Ireland
Title: High-pressure metamorphism in 475 Ma arc-continent collision in NW Ireland:  can geological observations ground-truth the results of numerical modeling?

Description:

David Chew has worked considerably on cold and deep metamorphic rocks in Achill, but also knows a great deal about the timing of collision and metamorphism along the entire belt of Dalradian (former continental passive margin sedimentary) rocks in NW Ireland and Scotland.  Ian Sanders will look at the unusually high temperature and high pressure metamorphic rocks that occur in the Ox Mountains of Co Sligo.  The hope is that some of the dynamic results of Celine Tirel’s models might find a match in the changes of pressure and temperature with time that we infer for these Irish rocks.
