Gravity and magnetic data are fundamental tools to investigate lithospheric structures over a wide range of spatial scales. The expansion of innovative acquisition systems (airborne, helicopter and UAV) and satellite surveys has considerably increased the volume, resolution and diversity of potential field datasets. These developments raise important challenges related to data acquisition, processing, harmonization, levelling and integration of heterogeneous datasets into coherent regional grids. The integration of gravity and magnetic data with complementary geological and geophysical information (e.g. petrology, geochemistry, structural geology, seismic, electromagnetic) provide powerful constraints on the architecture and tectonic evolution of the lithosphere in various tectonic settings. We invite contributions combining gravity and/or magnetic data with complementary geological and geophysical constraints through joint inversion, forward and inverse modelling, machine learning or other innovative approaches. Contributions spanning scales from local to lithospheric, addressing methodological developments, data processing, uncertainty assessment, and applications across a broad range of tectonic settings are particularly welcome.
