Crustal 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. Identification of this crustal signature in mantle-derived rocks (such as mid-ocean ridge basalts or kimberlites) is proof of crustal recycling.

- Le recyclage de la croûte océanique est un processus tectonique, par lequel les matériaux de surface de la lithosphère sont recyclés dans le manteau par subduction. Les plaques entraînées par la subduction importent des composés volatils et de l'eau dans le manteau, ainsi que des matériaux crustaux qui ont une signature isotopique différente de celle du manteau primitif. L'identification de cette signature isotopique crustale dans les roches dérivées du manteau (comme les basaltes ou les kimberlites de la dorsale médio-océanique ) est la preuve d'un recyclage de la croûte océanique.

- Il riciclo crostale è un processo tettonico in cui il materiale superficiale della litosfera viene riciclato all'interno del mantello terrestre per (o "erosione da subduzione") o per delaminazione. Le porzioni di placca in subduzione, i cosiddetti "slab", trasportano nel mantello non solo acqua e composti volatili ma anche materiale crostale e, poiché quest'ultimo ha una segnatura isotopica diversa da quella del mantello primitivo, il riconoscimento di tale segnatura in rocce derivanti da magmi provenienti dal mantello, come le kimberliti o i basalti delle dorsali oceaniche, fornisce una prova dell'esistenza del riciclo crostale.

- 地殼再循環（英語：Crustal recycling）是一種地質構造過程，該過程能把岩石圈的地表物質經過俯衝侵蝕或地殼分層剝離作用再循環到地幔中。 此過程能將揮發性化合物，水以及地殼物質隨俯衝板塊片進入地幔，同時也將地殼中的同位素帶入地幔。地殼再循環的證據是在地幔衍生的岩石（如大洋中脊玄武岩或金伯利岩）中找到地殼物質。 (zh)
