Lithospheric extension
Web6 jun. 2024 · Preliminary lithospheric thinning was induced by the extension of the NCC resulting from trench retreat of the Paleo-Pacific plate at ~140-120 Ma. Then, decompression melting of the lithospheric mantle caused pervasive melts in the weakened lithospheric mantle, resulting in the lithospheric mantle having a low viscosity … WebWe have carried out numerous projects related to lithospheric extension in the Basin and Range province--from the study of metamorphic core complexes to the slip histories of normal faults that cut the brittle crust, producing the corrugated topography of …

My work focused on the mapping and processing of preliminary geophysical data (e.g., magnetic, induced polarization, and gravity surveys) using Geosoft Montaj. In order to ensure efficient and consistent map production, I created templates and control scripts for the software. Web6 dec. 2024 · Late Mesozoic to Cenozoic regional extension within the NCC was due to an eastward retreat of the subduction Paleo-Pacific Plate, resulting in large-scale lithospheric thinning (>100 km) in eastern Asia and the formation of the amount of MCCs [ 5, 6 ]. The LP is a typical region of the lithospheric thinning in the Late Mesozoic of the NCC.
