The main goal of my PhD project is to study ureilitic meteorites in order to shed light about their formation processes. In detail, my work is focused on the investigation of carbon phases, mainly present in ureilites like diamond and graphite. This project will allow us to determine what processes occurred on ureilites Parent Body or during the evolutionary history of their asteroid, studying also the shock level degree on ureilites.

The investigation will be performed using different analytical techniques:

  • Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) microanalysis system to examine textures and composition of ureilites fragments.
  • Raman Spectroscopy (RS), to characterize minerals and in particular the carbon phases, to apply a geothermometric approach on graphite.
  • X-ray diffraction (X-Ray Powder Diffraction-XRPD and X-Ray Single-crystal Diffraction-XRSD) to characterize the sample phases and to estimate the crystallite size of minerals.
