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.
What else can I help you with?
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.
How does the age of the oldest continental crust compare to the age 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.
What happens to an oceanic plate as it pushes against another plate?
When an oceanic plate pushes against another plate, the denser oceanic plate is usually forced underneath the other plate in a process called subduction. This can create deep ocean trenches, volcanic arcs, and earthquakes along the boundary between the plates.
Are the oldest rocks on land or in the ocean?
The oldest rocks are typically found on land, as they have not been eroded away by oceanic processes. The oldest known rocks on Earth are found in Western Australia and are estimated to be around 4 billion years old.
Where in geographic location is oceanic plate found?
Oceanic plates form the 'floors' of the worlds oceans.
What is the result when ocean floors spread?
oceanic trenches and volcanoes from the rising magma.
Where does the oldest rock take place at on the ocean floor in sea-floor spreading?
Far from the mid oceanic ridge, near the continental margin (oldest oceanic rock ages 200 mya)
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 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 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.
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 old is the oceanic crust?
It varies, but the oldest part is 180 million years old
Where in relation to a mid ocean ridge would you find the oldest oceanic lithosphere?
the bottom
Where would you expect to find the oldest rock on the oldest floor?
Somewhere at the bottom of the Marianas Trench you would find the oldest rock of the oceanic crust. Somewhere else, however, there are older rocks on the ocean floor--those deposited by icebergs that have broken off of glaciers. Those erratic rocks could be much older than the oldest oceanic crust.
In the Atlantic Ocean basin where is the oldest oceanic lithosphere found?
i dont know hahhaah loser
How many floors in world abyss?
30 floors
