PhD position in LA-ICPMS U-Pb carbonate dating at Trinity College Dublin, Ireland

The Department of Geology at Trinity College Dublin, Ireland, seeks applicants for a fully-funded 3 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. A post-doctoral researcher has already undertaken two years's method development work on this project.

The successful candidate will apply these U-Pb dating techniques to carbonate unknowns. Dating targets include:

  1. vein calcite which constrains the timing of deformation in deformed carbonate successions (the Alps, Irish Variscan);
  2. dating carbonate veins and cements in carbonate-hosted ore bodies such as the Irish Pb-Zn orefield;

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 3 years. 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. (

The position is fully funded for three 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. To apply, please send a full CV and contact details of at least 2 academic referees, together with a letter of motivation, to Dr David Chew at from whom further particulars may also be requested. The deadline for applications is 26th April 2019 for a 1st September 2019 start. Applications received after this deadline can only be evaluated if the position is not filled.
