Ore-forming fluids expelled from magmatic carbonatites - high-resolution determination of chemistry and element distribution in fluid inclusions

Objective



Research obJectives and content
The project intends to study fluid inclusions which represent the primary composition of fluids expelled from carbonatites. Due to their extreme element enrichment these fluids have high potential to form ore deposits of high economic value. The technique we will dominantly apply is a newly developed Synchrotron XRF configuration which allows a resolution of analysis on the micron scale. That method can determine the element distribution and content in bulk inclusions and even in single daughter minerals by non-destructive means. This advantage over other analytical techniques provides the possibility to determine the daughter crystals mineralogically by Raman spectroscopy. The combination of both methods and supporting whole rock extraction methods can yield the bulk composition of the fluids as well as the element distribution between different H20- CO2-salt proportions and between fluid and various daughter minerals present. The aim is, by using new developments in Synchrotron XRF and Raman spectroscopy, to get a comprehensive characterization of highly enriched carbonatitic fluids, and to study mechanisms of element distribution between mineral / fluid, fluid / fluid, and fluid / melt.
Training content (obJective. benefit and expected impact)
With the envisaged cooperation with Prof A. Rankin and Kingston University as a whole I expect a high-level training in analysing techniques of fluid inclusions by a research team with international recognition with respect to experience and know-how in that field of research. The stay at Kingston University would furthermore enhance cooperation and bilateral exchange of analytical facilities (as the Hamburg Synchrotron Lab and facilities in Britain) between German and British research centres in general. I will use the opportunity to apply the training gained at Kingston to extend and deepen research techniques when back at my home university.
Links with industry / industrial relevance (22)
Kingston University and its fluid inclusion research group in particular has tight bonds with mineral exploration companies world-wide and with heating-freezing stage manufacturers in Britain. The herein intended new analysing techniques for that type of ore-forming fluids may have applications for any companies dealing with hydrothermal ore deposits and with fluid-analysing techniques.
