Description:
The study of the discontinuity between the Earth crust and upper mantle, the so-called
Moho, and of the lithospheric architecture in general, has several important applications in exploration
geophysics. For instance, it is used to facilitate the inversion of seismic-related data, in order to obtain
important information on the sedimentary layers or to study the Earth’s heat flux. In this paper,
the Levant crustal structure is being investigated starting from the inversion of gravity disturbances
coming from a global geopotential field model based on ESA GOCE satellite mission integrated with
seismic derived information. In the considered area, which is of particular interest because of its
richness from the resources point of view, the deep crustal structure is still a matter of study due to the
presence of a thick sequence of sedimentary layers, deposited within geological eras by the Nile River.
Within the current work, the shape of the Oceanic domain in correspondence to the Herodotus Basin
and the Cyprus Arc has been clearly defined. Moreover the nature of the Levantine Basin and of the
Eratosthenes crust has been investigated by a set of ad hoc tests, finding the presence of continental
crust. Finally, the Moho depth and the crustal density distribution have been retrieved. Several
localized anomalies, in the Cyprus area, have been identified and modelled too, thus confirming the
presence of heavy material, with a thickness up to 10 km, in the sedimentary layer and shallower
part of the crust.
