The oldest in-situ oceanic lithosphere is found at lithospheric subduction zones, where oceanic crust is being drawn into the mantle. These would normally be the point furthest away from its point of origin at the mid-ocean ridge.

However the oldest remnant of oceanic crust found on earth dates from the early Archean when the lithosphere began to develop and are a product of obduction (where slivers of oceanic crust are thrust onto a continental crustal plate rather than below them). An example would be the Jamestown Ophiolite Complex of the Barberton greenstone belt in South Africa which formed approximately 3.5 billion years ago.

Where are the oldest layers of rock on the sea floor?

The oldest layers of sea floor would exist at the bottom of the Marianas Trench, where oceanic plate subduction is occurring. The subducting oceanic plate is less than 200 million years in age.

Where is the youngest sea floor found?
