Nittrouer and Hallet Glacial-Marine Sedimentation as a Recorder of Tectonic, Climatic and Sea-Level Dynamics on Active Continental Margins
a) Overview Statement Glacial-marine sedimentation responds to and provides sedimentary archives for a diversity of important processes associated with continental-margin dynamics. Tectonic convergence and subduction on active margins lead to uplift and volcanism that commonly (in temperate and high...
