Rare ultrahigh-temperature–(near)ultrahigh-pressure (UHT–near-UHP) crustal xenoliths erupted at 11 Ma in the Pamir Mountains, southeastern Tajikistan, preserve a compositional and thermal record at mantle depths of crustal material subducted beneath the largest collisional orogen on Earth. A combination of oxygen-isotope thermometry, major-element thermobarometry and pseudosection analysis reve...

W.L. Griffin, Suzanne Y. O'Reilly and N.J. Pearson GEMOC, Dept of Earth and Planetary Sciences, Macquarie University, NSW 2109, Australia [email protected] It has become conventional wisdom that xenoliths of eclogite and garnet pyroxenite derived from cratonic subcontinental lithospheric mantle (SCLM) represent fragments of subducted ocean floor, implying that the SCLM has grown by a litho...
