WebThe plot of crustal reworking represents the amount of post formational alteration undergone by the crust. The dramatic increase in crustal reworking and reduction in the rate of crustal growth at approximately 3.6 Ga represents the onset of subduction and plate tectonics. Modified from [23] Lithological dating [ edit] Weboceanic and continental. Oceanic crust is somewhat more dense than continental crust. This difference causes oceanic crust to ‘ride lower’ in Earth’s mantle and form the basins that contain the oceans.

WebDec 24, 2024 · Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other. As magma that wells up from these rifts in Earth's surface cools, it becomes young oceanic crust. The age and density of oceanic crust increases with distance from mid-ocean ridges. Advertisement. WebCrustal recycling is a tectonic process by which surface material from the lithosphere is recycled into the mantle by subduction erosion or delamination. The subducting slabs carry volatile compounds and water into the mantle, as well as crustal material with an isotopic signature different from that of primitive mantle.
