Editorial: Source or sink? Erosional and depositional signatures of tectonic activity in deep-sea sedimentary systems

This Research Topic aimed to assemble contributions that investigated the distribution of erosion and deposition in the deep-sea and to explore its linkage with tectonic activity. A diverse range of fourteen papers cover the sedimentary processes (e.g., turbidity currents, mass-wasting), geomorphic elements (e.g., canyons, basins) and stratigraphic architectures (e.g., channels, lobes) that are indicative of tectonic shaping of the deep-sea environment across a range of tectonic settings, e.g., extensional, convergent, and strike-slip. Contributions covered a range of modern studies to those in deep geological-time and utilised a range of research approaches, from fieldwork to subsurface studies, to yield new insights on one or more of the research areas highlighted above. The resulting collection forms an anthology of Original Research and Reviews, which better constrain sediment routing systems in the slope and basin-plain and develops new concepts for the advancement of future source-to-sink studies. Hence, this Research Topic documents sedimentary processes, geomorphic elements and stratigraphic architectures of erosional and depositional signatures of tectonic activity in deep-sea sedimentary systems.
