Multi-observable Inversions for the thermochemical structure of the Earth

Multi-observable Inversions for the thermochemical structure of the EarthThe lithosphere and sublithospheric upper mantle (above 410d) are highly heterogeneous in their chemistry, thermal structure and physical properties. Lateral discontinuities (i.e. sharp changes in the thermal and/or compositional structure) in these regions are known to correlate with the location of seismically active zones, oil producing basins, foci of magma intrusion/production, and giant ore deposits. Understanding the fine-scale thermochemical structure of the lithosphere and sublithospheric upper mantle is therefore one of the most important goals in Geosciences

This project aims to develop thermodynamically-constrained multi-observable probabilistic inversions schemes, which have the potential to overcome the problems affecting other traditional inversions methods and provide realistic estimates of the present-day thermochemical structure of the lithosphere and upper mantle. The complete methodology has been recently published () and we are currently working on expanding it and applying it to different continental areas.
