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. WebThe key bit that is missing is that there are two kinds of crust, oceanic and continental crust which have different properties, and thus, different behaviors, and only one of these types, oceanic, is efficiently recycled. To understand why this is the case, we need to add some detail about these two types of crust and consider what this means for the way plate …
