Hontomín (N Spain) hosts the first Spanish CO2 storage research plant. The geophysical characterisation of the site included the acquisition of a 36 km2 3D seismic and a 16 km2
3D microgravimetric datasets. The integration of these data is here used to: (1) reproduce the deep structure and topography of the basement; (2) quantify the thickness of the Triassic
Keuper evaporites, located between the sedimentary succession and the metamorphic basement; and (3) establish relationships between the faults interpreted in the seismic data
and those inferred from the gravimetric data in the basement. The geometry of the sedimentary succession and structures interpreted from the seismic volume were used to constrain
the inversion of the microgravity data: i.e. their gravimetric signature was calculated and then removed from the Bouguer Anomaly, thus reducing the uncertainty in the inversion
process. The derived top of the basement geometry was used, along that of the top of the Triassic Keuper, to calculate the salt thickness.
