Project Title: Detrital zircon geochronology in the west of Ireland in support of Tellus geophysics interpretations
Project Description: Tellus geophysical surveys are providing a wealth of new information about the tectonic amalgamation of Ireland. This proposal requests funds to complement new Tellus data and interpretation with a zircon geochronology program to study successions in Mayo and Connemara.
We present here three research goals, all of which will use interpreted Tellus data:
- a test of the age and history of a proposed suture between Ordovician Clew Bay Complex ophiolitic rocks and Dalradian supracrustal rocks;
- a test of the provenance of rocks in the South Connemara Group, which has implications for sites of gold mineralisation;
- a test of terrane amalgamation through understanding Silurian rocks that cover tectonic sutures. The greatest impacts of our work will be in scientific discoveries, demonstration of methods that add value to collection and interpretation of Tellus geophysical data, and through training a TCD undergraduate in research methods.
