Continental shelves as detrital mixers: U-Pb and Lu-Hf detrital zircon provenance of the Pleistocene–Holocene Bering Sea and its margins
Matthew A. Malkowski, Samuel Johnstone, Glenn R. Sharman, Colin J. White, Daniel S. Scheirer, Ginger Barth
2022, The Depositional Record (8) 1008-1030
Continental shelves serve as critical transfer zones in sediment-routing systems, linking the terrestrial erosional and deep-water depositional domains. The degree to which clastic sediment is mixed and homogenized during transfer across broad shelves has important implications for understanding deep-sea detrital records. Wide continental shelves are thought to act as capacitors...
