Isotopic and chemical evolution of hydrothermal sulphide chimneys
Dr Julian Menuge (UCD), DrBramleyMurton (NOC, Southampton), Dr Ian Butler (University
of Edinburgh) and Dr Adrian Boyce (SUERC)
This project will examine the spatial variationof Fe-Zn-S isotope compositions in the sulphide and sulphate minerals of black smoker chimneys, including an assessment of how these evolve with time and chimney architecture. The isotopic compositions will be closely integrated with textural observations and with minor element compositions. The objectsare to build up a model of how the isotopic and chemical variations come about, consider the implications for the formation and evolution of fossil volcanic massive sulphide deposits, and to suggest ways in which isotopic and geochemical analysis may aid in mineral exploration for VMS deposits.
The research will be lab-focussed, involving MC-ICP-MS isotopic analysis of Fe and Zn, laser ablation S-isotope analysis, electron microprobe analysis and use of thermodynamic modelling software (Geochemists' Workbench).
We are seeking applicants who are willing to apply for an Irish state-funded scholarship (IRCSET EMBARK postgraduate scholarship scheme: www.ircset.ie). The scholarship competition is very competitive and we are therefore seeking candidates with a first class honours BSc or Masters-level qualification in Geology or Geochemistry. Research experience in hydrothermal geochemistry, or in any of the above techniques, would be a distinct advantage but is not essential. Applicants of any nationality, country of residence and age are eligible to apply.
The deadline for submission of expressions of interest to Dr Julian Menuge (j.f.menuge@ucd.ie), from whom further information can be obtained, is Monday 6th February. Expressions of interest should include CV, the names and email addresses of three referees and a transcript showing the grades or marks obtained in all university courses completed to date.
