Abstract

Summary

One of the major results of the “experimental jOint inveRsioN” project (XORN - https://xorn-project.eu/) is a complete three dimensional model of the whole crust in the Mediterranean Sea region estimated by jointly inverting gravity and magnetic fields. In this work we present details about the inversion as well as the resulting model.

The obtained model has a spatial resolution of about 15 km and provide information about density and magnetic susceptibility distributions as well as the depths of the main geological horizons.
