Evidence for rutile-bearing eclogite in the mantle sources of the Cenozoic Zhejiang basalts, eastern China

Cenozoic intraplate basalts are widely distributed along the southeastern margin of Eurasia. Both carbonated and eclogitic/pyroxenitic components, which are considered related to oceanic crust recycling, have been identified in the mantle source of these basalts. However, the origin of the recycled oceanic crust and the genetic relationship between different source lithologies remain unclear. Here, we assess the source lithologies of late...
