Exhumation of ultra-high pressure (UHP) rocks modulated by rifted margin-subduction feedback: Implications for their preservation in old collisional orogens
Résumé
Subducted magma-poor rifted margins can efficiently exhume UHP rocks. Conditions for magma-poor rifted margins may have arisen during Earth's middle age. Abundant magma-rich margins in Early Earth prevented UHP rocks to exhume.
