- Eocene initiation of Ross Sea dextral seismogenic faulting and implications for East Antarctic neotectonics
No full textThe Ross Sea region of the East Antarctic plate provides evidence for intraplate tectonic activity in
Cenozoic times. Still unresolved are the cause, timing and kinematics of this intraplate tectonism. By
integrating and discussing the different (kinematic and temporal) signals of Cenozoic tectonism, intraplate
dextral shearing is recognized as the main tectonic regime controlling the structural architecture of the Ross
Sea region from the Mid-Eocene (c. 40–50 Ma) onward. We speculate that propagation and persistence of this
tectonic regime through time constitutes a feasible seismogenetic framework to explain past and current
tectonism in the Ross Sea region
