- •
The Purang peridotites are not the complementary mantle residues of spatially associated oceanic crust.
- •
The Purang peridotites may represent ancient subduction-modified SCLM domains.
- •
The Purang peridotites have been rejuvenated by late-stage percolating N-MORB melts.
- •
A deep mantle recycling model is preferred to reconcile the presence of SuR-UHP mineral assemblages.
