The terminal category of ocean basins is characterised by the greatest mean sediment thickness (4311m) and greatest percentage area of submarine fans (7.2%) of any ocean basin. In the 21st century, insights from seismic imaging and other techniques have led to updates to the Wilson Cycle to include relationships between activation of rifting and mantle plumes. The evolution contains five stages which are embryonic stage, juvenile stage, mature stage, declining stage, terminal stage, mature stage, and continental collision. The three main ocean zones are the daylight zone, the twilight zone, and the deep ocean, which is further divided into the midnight zone, the abyss, and the trenches.

In: Udintsev GB (ed) International geological atlas of the Pacific Ocean. The Tethys seaway also opened during this rifting phase as Europe pulled away from Africa. The narrow ocean basin may be caused by sediment input that make the young mountain exist along and around the flanks. What you need to know is that in this very first stage you can see a complex system that is marked by the linear rift valley and or the continents. Ocean basin that will experience the evolution is the one that has an active tectonic margin.

In this stage, the sample was at the temperature at the bottom of the partial annealing zone, the temperature drops rapidly from 130 C to 75 C, with the temperature difference of 55 C and the cooling rate of 0.91 C/Myr (the evolution trend after 60 Ma is consistent with the evolution trends of the other four samples). There are three stages in the history of a basin: mature (where a broad ocean basin widens, trenches eventually form, and subduction starts); declining (where the sea floor is eliminated by subduction and an oceanic ridge forms); and terminal (where the sea floor is finally eliminated and continents collide to form a continental mountain chain).
