| 英文摘要 | Submarine canyon-channel systems have been documented in the Parece Vela Basin, West Mariana Ridge; however, the mechanism of the formation and controlling factors remain poorly understood. Based on high-resolution multibeam bathymetric data and two-dimensional(2D) seismic profiles, we identified and mapped the submarine canyon-channel system along the middle segment of West Mariana Ridge in the Philippine Sea. These submarine canyon-channels show a main W-E orientation at depth of 2 000–4 500 m. They are approximately 72–128 km in length and 1.3–15 km in width, and their canyon heads are adjacent to the seamounts with several branches. The upper reaches of submarine canyon-channels are characterized by deeply incised, narrow, V-shaped thalwegs, suggesting the powerful erosion of gravity flows. The distinguished sediment waves are suggested to be resulted from the interaction of turbidity currents and seafloor. Our observations demonstrate that gravity flows originated from the collapses of seamount flanks plays a vital role in developing the submarine canyonchannel system along the West Mariana Ridge. This work provides better understanding of erosion,transport, and deposition of sediments from subducting ridges to deep-water basins, and also new insights into the origin and evolution of submarine canyon-channel systems along subducting ridges. |
