Composition of the Continental Crust (2014, background): “It may be that this mafic lower crust was never produced, or that it formed but was removed from the crust, perhaps via density foundering (R. W. Kay and S. M. Kay, 1991; Gao et al., 1998b; Jull and Kelemen, 2001).”
Recycling lower continental crust in the North China craton (2004, background): “Because of this density contrast, mafic lower continental crust (together with the underlying lithospheric mantle) can be recycled into the mantle when granulite is transformed into eclogite during crustal thickenin”
Subduction initiation: spontaneous and induced (2004, background): “The concept of delamination continues to evolve, with one mechanism involving the dpeeling offT and sinking of lithospheric mantle as envisaged by Bird and another the sinking of gravitationally unstable mantle and lower crust by Rayleigh-Taylor instability [62].”
Near‐surface diagnostics of dripping or delaminating lithosphere (2008, methodology): “The density contrast can arise as a result of thermal contraction of the cold mantle lithosphere, although compositional density variations of the lower crust have also been called upon to explain lithospheric instability [Jull and Kelemen, 2001; Elkins-Tanton, 2005].”
Crystallization of oxidized, moderately hydrous arc basalt at mid- to lower-crustal pressures: implications for andesite genesis (2012, unknown): “The residual rocks would be gabbros and would be buoyant relative to peridotite, so post-magmatic cooling into the eclogite facies, or collisional events depressing the residual gabbros into the eclogite facies, in both cases followed by eclogite delamination (Jull and Kelemen 2001), may be necessar”
Lower Crustal Magma Genesis and Preservation: a Stochastic Framework for the Evaluation of Basalt–Crust Interaction (2005, methodology): “Erosion (Montgomery et al., 2001), lower crustal flow (Meissner & Mooney, 1998), delamination (Kay et al., 1992; Lee et al., 2001; Saleeby et al., 2003), and Rayleigh–Taylor type density instability ( Jull & Kelemen, 2001 ) have all been called upon as mechanisms to remove crustal material, and sev”
