The evolution of the continental crust and the onset of plate tectonics

CJ Hawkesworth, PA Cawood, B Dhuime - Frontiers in earth science, 2020 - frontiersin.org
The Earth is the only known planet where plate tectonics is active, and different studies have
concluded that plate tectonics commenced at times from the early Hadean to 700 Ma. Many …

Arc magmas sourced from mélange diapirs in subduction zones

HR Marschall, JC Schumacher - Nature Geoscience, 2012 - nature.com
At subduction zones, crustal material enters the mantle. Some of this material, however, is
returned to the overriding plate through volcanic and plutonic activity. Magmas erupted …

High Sr/Y and La/Yb ratios: the meaning of the “adakitic signature”

JF Moyen - Lithos, 2009 - Elsevier
The name of “adakite” is used to describe a far too large group of rocks, whose sole common
feature is high Sr/Y and La/Yb ratios. However, such a signature can be achieved via …
