well none of the ocean crust is more than 175 million years old because subduction happens. subduction is when an ocean plate moves slowly into a continent plate and then goes under it and get devoured by the mantle because its lighter than the continental crust. so the answer to your question would be around the edges of the pacific plate.

TaigaThe oldest rocks in the Atlantic Ocean are found in the northeastern part near Greenland and Scandinavia. These rocks are estimated to be about 250 million years old, dating back to the Paleozoic era.
The Atlantic Ocean started to form about 200 million years ago, shortly after the beginning of extensive volcanic activity, associated with tensions in the continental crust between nowaday's Afrika and North America. The oldest oceanic crust in the Atlantic Ocean is therefore found off the continental slopes of the USA and Northwest Africa.
The continental shelfs, of course, comprise rocks below their sedimentary cover that often are much older than the oldest oceanic crust.

How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
The oldest rocks are located at mid-ocean ridges?
Actually, the oldest rocks on Earth are found in Western Greenland, Australia, and Canada, with ages exceeding 3.8 billion years. The rocks at mid-ocean ridges are much younger, typically less than 200 million years old due to the continuous process of seafloor spreading and subduction.
Why are the oldest rocks found in Iceland?
The oldest rocks in Iceland are found because of its location over the Mid-Atlantic Ridge, where new oceanic crust is continually formed. As a result, the rocks at Iceland's boundary represent some of the oldest on Earth as they have not been subjected to the intense tectonic activity and recycling that typically occurs at plate boundaries.

Are the oldest rocks of the oceanic crust found in deep ocean trenches far away from active mid-ocean ridges?
No, the oldest rocks of the oceanic crust are typically found near the continents where they have had more time to form and accrete. Deep ocean trenches are usually associated with subduction zones where tectonic plates are being forced underneath each other, rather than locations where new oceanic crust is forming.
