Abstract:
Mercury is classically dominated by contractional features at a global scale (e.g. Watters et al.2009, EPSL]).
Nonetheless, numerous evidences of strike-slip kinematics have been found on Mercury Dual Imaging System
(MDIS) camera images mainly derived from the three MESSENGER flybys and acquired near the terminator. This
proves that several lobate scarps and high-relief ridges may be interpreted as transpressional structures more than
thrust and back-thrusts systems. This finding may support either tidal despinning or residual mantle convection
on ruling the nucleation and development of lobate scarps, although within the general framework of planetary
contraction and cooling. In addition, the presence of faults with a clear strike-slip kinematic component may
possibly affect future estimates of the hermean radius shortening.
