A two-stage thickening and stabilization model for the formation of cratonic lithosphere Hongliang Wang (UiB) How Archaean tectonics was capable of producing virtually indestructible cratonic lithosphere remains a topic of considerable debate. Recent geophysical and petrological studies refuelled the debate by …
