PhD position, LA-ICPMS U-Pb carbonate dating, Dublin, Ireland
The Department of Geology at Trinity College Dublin, Ireland, seeks applicants for a fully-funded four-year PhD in U-Pb LA-ICPMS carbonate dating.
The approach involves image mapping by laser-ablation quadrupole-ICPMS, which can circumvent the problems of low U contents and/or high initial Pb in calcite/dolomite by identifying zones of high U/Pb ratio. U-Pb ages are generated from these LA-ICPMS image maps and where there is a sufficient spread in U/Pb age ratio, age uncertainties as low as ±1% can be obtained. A post-doctoral researcher has already commenced method development work on this project.
The successful candidate will apply these U-Pb dating techniques to carbonate unknowns. Dating targets include:
- Carbonates associated with key time intervals in Earth history, particularly those associated with ancient climatic changes (e.g. Neoproterozoic carbonate sequences in Namibia);
- Dating carbonate veins and cements in carbonate-hosted ore bodies such as the Irish Pb-Zn orefield;
- Vein calcite which constrains the timing of deformation in deformed carbonate successions (the Alps, Irish Variscan);
- Constraining the timing of reservoir-degrading cementation events in hydrocarbon basins (removal of porosity by diagenetic calcite).
Experience of independent geological fieldwork and laboratory work are highly advantageous.
The successful candidate will join a vibrant geochemistry group at Trinity College Dublin comprising seven principal investigators, seven post-doctoral researchers and over twenty PhD students.
The department has 2 LA-ICPMS instruments, a dedicated solution-ICPMS facility with a clean laboratory along with full mineral separation and sample preparation facilities. (http://www.tcd.ie/Geology/research/facilities/analyticallabs/).
The position is fully funded for four years and includes a tax-free stipend of €18,000/year along with full provision for fees, together with conference travel, laboratory and field work costs.
Applications are invited from highly-motivated and high-achieving geoscience graduates with a first or an upper second class division first degree (or equivalent) and who have been ordinarily resident in the EU/EEA/Swiss Confederation for a minimum of the last three years.
The deadline for applications is 20 April 2017 for a 1 September 2017 start.
Applications received after this deadline can only be evaluated if the position is not filled.
