Mantle evolution
Since its formation, planet Earth underwent a complex evolution that progressively differentiated its original composition. The Hadean differentiation events left an indelible mark on the Archean mantle, which was lately modified by the separation of the crust and by the global tectonics.
Our research group uses trace element and isotope geochemistry on mantle and mantle derived rocks to add new knowledge on a series of problems spanning from the effective chondritic composition of the Earth to how fluid mobile elements were added to the mantle and how their deep cycle evolved through time.
Crustal growth
The continental crust is the archive of Earth history and its formation and evolution modified the composition of the mantle and the atmosphere and supported the emergence of life. The continental crust is chemically evolved and, although representing a volumetrically minor component of our Planet, it dominates the Earth’s budget for many incompatible elements (e.g. Li, Cs, Th).
Our research group uses trace and isotope geochemistry to shed light into the rate and mechanism of continental crust evolution in different tectonic settings.
Volcanic systems
Despite representing a threat to society and the environment, volcanoes have played a fundamental role in shaping our planet and represent the most important source of geothermal energy. The products of volcanic activity (lavas and pyroclastic rocks) hold clues to the conditions and timescales of magma storage in the Earth’s crust and those that lead to eruption.
Our research group uses a combination of field observations, textural analyses, geochemical, isotopic and geochronological data as powerful tools to unravel the inner workings of volcanic systems and understand their eruptive behaviour.
Subduction zones
Recycling of volatiles and incompatible elements at convergent margins reflects the dynamism of our planet. Understanding the mechanisms and the processes of element mobility in subduction zones is key to unravel Earth’s evolution since the onset of plate tectonics.
Our research group uses trace element and isotope geochemistry to unravel subduction zone processes using both the natural rock record and experimental approaches
