Granite-related W-Sn deposits are invaluable to our society because they contain a high number of critical minerals that are essential in industrial and technological applications for a sustainable future. The determination of the conditions that dictate the structural emplacement and geometry of granite-related W-Sn deposits remains an unanswered and highly contested issue. The current knowledge in the field originates from theoretical ...

Spatial and temporal petrological-geochemical variations in the West Aegean arc: influence of local geodynamics parameters on magma genesis Ghent University
Three volcanic islands of the South Aegean arc, representing a 25km across-arc setting, will be studied petrologically and geochemically studied will improve our understanding of the different sources and processes contributing to magma genesis in continental subduction zone settings. This will be achieved through study of thin sections, chemical whole rock analyses (ICP-OES, ICP-Q-MS, MC-ICP-MS) and mineralogical analyses (SEM-EDS and ...
Characterization of porous geomaterials in 2D and 3D Ghent University
Optical and fluorescence microscopy visualizes pores in 2D. CT data allows characterization of complex pores in 3D. This urges for a calibrated system by fusing the standard fluorescence and petrographical microscopy images with 3D data of the high-resolution CT scanners. By fusion of XRF data, a correct characterization of geomaterials will be obtained in a structurally and chemically calibrated way.
Multi-disciplinary 3D characterisation of complex pore-networks and minerals of geomaterials from sub-micron to centimeter scale Ghent University
3D characterisation of minerals and pore-structures at a pore-scale level will be obtained by fusion of 2D and 3D data, derived from different traditional and high-technological imaging techniques. Chemical and structural 3D data gained from high-resolution X-ray CT and micro X-ray fluorescence will be linked to 2D information obtained by optical and scanning electron microscopy combined with energy-dispersive X-ray spectroscopy.
The origin of the tholeiitic and calc-alkaline differentiation trends on Methana and Santorini (Aegean Arc): crustal contamination, polybaric fractionation or magma mixing Ghent University
The volcanic centrums of Methana and Santorini (Aegean Arc) are dominted by calc-alkaline and tholeiitic deposits, respectively, and provide a unique opportunity to investigate the origin of these trends. The relative importance of crustal contamination, polybaric crystal fractionation and magma mixing will be assessed by petrographic studies and analyses of whole rocks for major and trace elements, and radiogenic isotopes.
Archaeometrical research of painted objects Ghent University
This research project is situated on the border between natural sciences, archaeology and art-history and contains the examination of painted objects. Different methods of analysis are used to investigate pigments, binders and supports. This project tries to solve different types of questions on objects from different periods (prehistory, middle ages, antiquity) and locations.
Relationship between the microstructure and geochmistry of cacite and quartz veins: petrogenetic implications Ghent University
Calcite and quartz veins are common structures in the Earth's crust, but their trace element geochemistry is virtually unknown. The relationship between the veins' composition, their microstructures, and the composition of the host can provide new insights into their petrogenetic history. This has implications for chemical models of the Earth's crust and the formation of ore deposits.
Development of peripheral equipment for conditioned X-ray nanotomography measurements Ghent University
A nanofocus X-ray tomograph is a device that allows non-destructive scanning of the interior of materials and objects with a spatial resolution better than one micrometer. This project proposal aims at the development of peripheral equipment at the new nanotomograph of the UGent which will allow to study samples under specific conditions such as controlled temperature, level of humidity, atmospheric pressure, atmospheric composition, tensile ...
PEtrological-geochemical variations in subduction-related magma's of the Aegean arc and their relationship with geodynamic parameters Ghent University
A petrological-geochemical study of the volcanic deposits of the Aegean arc will provide new insight into the relationship between the composition of arc magmas and geodynamical parameters. The study will use major-an d trace-element and isotopic (Sr, Nd, Pb) analyses on whole rocksm and laser-ablation analyses of trace elements and Sr isotopes in individual minerals.
