Coastal and Oceanic Landform (01.Abyssal Fan)

01.Abyssal Fan                                                                                                                                              Back to Coastal and Oceanic Landforms

  • It is also known as 

                           -deep-sea fans
                           -underwater deltas
                           -submarine fans

  • Abyssal fan formed by turbidty currents.
  • There  underwater geological structures associated with large-scale sediment deposition.
  • Alluvial fans  dramatically widths from several kilometres to several thousands of kilometres 

                    ex:Bengal fan

  • The slowing current has a reduced ability to transport sediments and deposition of the coarser grains begins, creating a submarine fan.
  •  The current continues to slow down reaches to the level bottom of the ocean. 
  • Fan shaped accumulation of sediment from riversthat is deposited at the submarine canyon within ocean basin.
