Are the oldest rocks of the oceanic crust found in deep ocean trenches far away from active mid-ocean ridges?

That is normally where they would be found; farthest away from the point at which they were initially formed.

Far from the mid oceanic ridge, near the continental margin (oldest oceanic rock ages 200 mya)

It varies, but the oldest part is 180 million years old

How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
Where are the elder parts of the ocean floor located?
Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.

What features of the ocean floor is the deepest?
The ocean basins are the result of tectonic forces and processes. All of the ocean basins were formed from volcanic rock that was released from fissures located at the mid-oceanic ridges. The oldest rocks found in these basins are approximately 200 million years old. This is a lot younger than the oldest continental rocks which have ages greater than 4 billion years. The reason for this discrepancy is simple. Tectonic processes destroy old oceanic rocks! Oceanic rock is returned to the Earth's mantlewhen oceanic crust is subducted. Many of these subduction zones occur at the continental marginswhere oceanic crust meets continental crust. Subduction also creates the ocean's deep trenches.

What is the age of the oldest ocean?
The oldest oceanic crust is in the west Pacific and north-west Atlantic. They are about 180 to 200 million years old.
