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] WebHere the Earth’s crust is spreading, creating new ocean floor and literally renewing the surface of our planet. Older crust is recycled back into the mantle elsewhere on the globe, typically where plates collide. The mid-ocean ridge consists of thousands of individual volcanoes or volcanic ridge segments which periodically erupt.
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.
