Deep continental roots and cratons
The formation and preservation of cratons—the oldest parts of the continents, comprising
over 60 per cent of the continental landmass—remains an enduring problem. Key to craton …

Earth's continental lithosphere through time
CJ Hawkesworth, PA Cawood… - Annual review of …, 2017 - annualreviews.org
The record of the continental lithosphere is patchy and incomplete; no known rock is older
than 4.02 Ga, and less than 5% of the rocks preserved are older than 3 Ga. In addition, there …

The complex life cycle of oceanic lithosphere: A study of Yarlung-Zangbo ophiolitic peridotites, Tibet
The ultramafic mantle sections of the Yarlung-Zangbo ophiolites (YZO) along the suture of

Continent stabilisation by lateral accretion of subduction zone-processed depleted mantle residues; insights from Zealandia
To examine how the mantle lithosphere stabilises continents, we present a synthesis of the
mantle beneath Zealandia in the SW Pacific Ocean. Zealandia, Earth's “8th continent” …
