Sylvain Mayolle
is a postdoctoral researcher in the project “Do volcanoes collapse retrogressively?” working on the structural analysis and modelling of Etna’s sub-marine flank.
Sylvain will particularly investigate the structures and blocks arrangement within the volcano flank, the seaward and northern boundaries, and how gravitational forces, potentially aided by a décollement level or salt deformation, drive this deformation. He will couple a multi-scale structural characterisation with new analogue modelling experiments which replicate gravitational flank deformation.
The integrated interpretation of marine data and analogue modelling data will improve our understanding of the offshore flank structural model, deformation kinematics, and the dynamics of the volcanic edifice.
Sylvain is a structural geologist specialised in brittle deformations. Previously he worked on the analysis of fracture distribution in analogue reservoir outcrops using Unmanned Aerial Vehicle photogrammetry processing and interpretation. This research was part of the NEMO project by Andrea Bistacchi's and ENI at the University of Milano.
In a previous project and during his PhD supported by “Total Energies”, Sylvain worked on the growth of fault damage zones in carbonate rocks. His research was based on a multi-scale analysis from satellite images and DEM to micro-scale and analogue modelling experiments developed at the Geosciences Montpellier Analogue Modelling Laboratory. He particularly performed new models of normal faults, monitored by high-resolution cameras to analyse deformation at a micrometre scale.
