The oldest ice cores (taken from the Antarctic) date back some 1.5 million years. There are some variables that can introduce error, but it (the error) will be small compared to the age of the recovered materials. This is not theory. Proven laboratory techniques allow us to make these statements. No one who understands the physics of the methods will gainsay them. The physics is not that difficult to get a handle on. But remove any religious (or other) blinders before looking at the science. A link is provided to the white paper on these core samples.

How does the age of the oldest continental crust compare to the age of oldest ocean crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
How does the age of oldest continental crust compare to the age oldest ocean crust?
The oldest continental crust is significantly older than the oldest oceanic crust. The oldest continental rocks, found in regions like Canada and Australia, are over 4 billion years old. In contrast, the oldest oceanic crust, located at the bottom of the Atlantic Ocean, is only about 200 million years old, as it is continuously created and destroyed through the process of plate tectonics. This stark difference highlights the stability and longevity of continental crust compared to the dynamic nature of oceanic crust.
How does the age of the oldest continental crust compare to the of the oldest ocean crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
Is the mid ocean ridge the location of the oldest ocean floor?
No, the mid-ocean ridge is actually where new oceanic crust is formed through volcanic activity. As the crust moves away from the ridge, it becomes older. The oldest oceanic crust is found near the edges of the ocean basins.

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.
How does the age of the continental crust compare to The age of the oldest oceanic crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
Where are the oldest rocks in the ocean crust?
The oldest rocks are actually on land but in the ocean crust they would be the rocks closest to land. The mid-ocean ridge forms new rocks. They are usually located in the middle of the ocean.
On the ocean floor where is the oldest rock?
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
How does the age of the oldest continental crust compared to the age of the oldest oceanic crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
Where are the oldest rocks located in the ocean crust?
The oldest rocks on the ocean floor would be those at the colliding edge of the plate boundary.Answer 2: The oldest of all oceanic rocks are on the Asian side of the pacific plate.
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
