The role
The researcher will undertake high precision isotope analyses (Mg, Cr, Si, O) of chondrules to investigate the early history of the solar system.
What will you be doing?
The project will focus on the timing and duration of chondrule formation. Using electron imaging techniques suitable samples will be identified and characterised. Isotopic analyses will be made through micro-drilling and multi-collection plasma mass-spectrometry at Bristol (Mg, Cr, Si isotopic measurements) and using ion-probe analyses (O), with partners in Nancy, France. High-precision Mg and Si analyses are well developed at Bristol, but Cr measurements require some further refinement, which will be an important initial objective. In all work will provide valuable new constraints on the timing (Mg, Cr) and provenance (Cr, Si,O) of chondrules, and how the latter influences the former.
You should apply if
The candidate needs to have extensive experience in high-precision isotope measurements using multi-collection plasma mass-spectrometry, clean lab work (including low, blank, silicate sample dissolution and ion chromatography techniques) and preferably meteorite petrology. Direct experience with the Cr isotope system would be advantageous. In addition to the laboratory work, the candidate will have to identify and prepare suitable samples for analysis, reduce the data, prepare manuscripts for journals and present at conferences. We seek a researcher who is keen to become an active participant in the functioning of our diverse, isotope group.
We welcome applications from all members of our community and are particularly encouraging those from diverse groups, such as members of the LGBT+ and BAME communities, to join us.
