Abstract:We modeled gravity data to explore Mercury’s internal structure and show the presence of crustal heterogeneities in density. We first evaluated the lithospheric flexure occurring in the spherical harmonic degree range 5–80, according to the flexural isostatic response curve. We thus estimated a mean elastic lithosphere thickness of about 30 $$\pm$$
±
10 km and modeled the crust-mantle interface, which varies from 19 to 42 km depth, according to a flexural compensation model. … Show more
