Trace element composition of mantle end-members: Implications for recycling of oceanic and upper and lower continental crust

Recycling of oceanic crust together with different types of marine sediments has become somewhat of a paradigm for explaining the chemical and isotopic composition of ocean island basalts. New high‐precision trace element data on samples from St. Helena, Gough, and Tristan da Cunha, in addition to r...
