OCEAN BASIN
Note: Your question is vague and confusing, but I will answer it based on what I understood.
AGES OF ROCKS IN OCEANIC BASIN
The density, age, as well as the thickness of oceanic crust and rocks increases as distance also increases away from the mid-ocean ridge in the ocean basin.
This only means that rocks within or near the ocean basin along mid-ocean ridge, is relatively young, and less denser, because they are newly formed from the solidified magma that came from the Earth's mantle. So this means, the oldest ones are farther from this region.
