SIMS chlorine isotope analyses in melt inclusions from arc settings

Chemical Geology (2016), doi:10.1016/j.chemgeo.2016.12.002

Call for proposal is now open.

We strongly encourage submission of projects for which we already have developed the method and have the required standards. Projects needing development (method and/or standard) will be considered, but may be scheduled with a lower priority.

The proposal can be found here. Methods, reference material available and expected precision are described on those 2 pages: standards and analyses.

Please send the proposal, to:

Dr. Anne-Sophie Bouvier, Laboratory Manager of the SwissSIMS by e-mail (swisssims@nullunil.ch) no later than November 1^st, 2017.

After a few months of testing we are pleased to announce that U-Pb protocols have been revised and instrumental setup has been optimized for U-Pb ages. We can produce concordant, accurate and precise ages (within 1%) for zircon. Testing has been performed for ages from Miocene to early Proterozoic.

Monazite U-Pb dating has also been achieved with good precision. For this mineral however quality may depend on the chemical composition of the sample due to possible matrix effects.

At this stage, spot size is ~ 25 micron across (2 microns deep), and smaller spot sizes will depend on the age and composition of the sample.

We are at the stage where we welcome users (Master students to senior researchers) to propose project for U-Pb geochronology. For the next few sessions any U-Pb analysis will still be considered development and no charge will apply.

This worhskop will take place in La Chaux de Fond and Lausanne, from April 18th to 21st. More info can be found here:
