Sign Up to like & getrecommendations! Published in 2020 at "Journal of Earth Science"
DOI: 10.1007/s12583-020-1307-9
Abstract: As an important part of the continental lithosphere, the continental lower crust can influence and control many important geodynamic processes, which are of great significance to the evolution of the lithosphere. Extensive plastic deformation is… read more here.

DOI: 10.1016/j.epsl.2020.116375
Abstract: Abstract It has been hypothesized that much of central and eastern Tibet coincides with gravitationally driven flow of weak lower continental crust. Magnetotelluric profiles throughout Tibet reveal several deep crustal zones of high conductivity inferred… read more here.

DOI: 10.1029/2023gl107606
Abstract: The viscoelastic lower crust beneath Kyushu Island, influenced by the volcanic arc, interplays with active crustal faults in this region and helps to shape local tectonics. In this study, we employed a three‐dimensional viscoelastic finite… read more here.
