Cratonic lithospheric mantle: Is anything subducted?

WL Griffin, SY O'Reilly - Episodes Journal of International Geoscience, 2007 - episodes.org
If the subcontinental lithospheric mantle (SCLM) formed through the repeated underthrusting
of oceanic slabs, peridotitic SCLM should resemble oceanic peridotites, and mafic rocks …

Major-and trace-elements in cratonic mantle eclogites and pyroxenites reveal heterogeneous sources and metamorphic processing of low-pressure protoliths

S Aulbach, DE Jacob - Lithos, 2016 - Elsevier
There is a growing body of evidence for the origin of cratonic mantle eclogite xenoliths by
low-pressure formation in now-recycled ocean floors. Because they have protoliths …
