Cratons record the early history of continental lithosphere formation, yet how they became the most enduring part of the lithosphere on Earth remains unknown1. Here we propose a mechanism for the formation of large volumes of melt-depleted cratonic lithospheric mantle (CLM) and its evolution to ...
Lithosphere strength controls oceanic transform zone structure: insights from analogue models SummaryOceanic transform zones have often been regarded as plate boundaries. The origin of their structural variability is poorly constrained. A simple obs... O Dauteuil,O Bourgeois,T Mauduit - 《Geophysical Jo...
To this purpose we use finite element methods and a reconstruction of regional plate boundaries appropriate for 30 m.y. B.P. A key role in the model is played by the dependence of two important plate-tectonics forces (slab pull and ridge push) on the age of oceanic lithosphere. The ...
Hence, it is reasonable to consider that once the oceanic lithosphere subducted into the lower mantle, its SOC portion will not in bulk return to the upper mantle, and thus contribute to the lower-versus-upper mantle compositional differentiation. We should note, however, that small SOC debris ...

The lithospheric mantle probably contained Archean enriched domains as well. Proterozoic enrichment may have accompanied shallow underplating of subducted oceanic lithosphere beneath the Churchill Province during amalgamation of the Laurentian supercontinent. There are strong analogies in isotopic composition, and...
The fore-arc lithosphere may be frozen at ~150–137 Ma, consistent with the termination of the Gangdese arc magmatism during this period. The Early Cretaceous ophiolitic massifs (137–123 Ma) were developed in relation to the reinitiation of the Neo-Tethyan oceanic lithosphere subduction, the ...
Thus the intuitive notion that diverging flow at the ridge axis due solely to plate spreading produces the axial valley is incorrect. Vertical mantle flow at the base of a stretching, accreting lithosphere and mantle flow associated with melt segregation can, however, lead to stress-supported ...
