Stages of Ocean Basin Evolution Embryonic rift valley forms as continent begins to split Great Rift Valley, Eastern Africa Juvenile sea-floor basalts begin forming as continental sections diverge Red Sea Mature broad ocean basin widens, trenches develop and subduction begins Atlantic Ocean Declining Subsequently subduction is initiated on one of the ocean basins margins and the ocean basin closes up. The characteristic is the existence of the continental margins in the ocean seafloor that creates the ocean basin. And here today in this article I would like to explain and inform to you about each stages so you can understand better. In the ocean plate, this process causes the seafloor spreading.

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).
