Continental Crust At Mantle Depths, August 2013, Vol. 9, No. 4
$20.00
The discovery of diamond and coesite in crustal rocks is compelling evidence that continental material has experienced pressures that can be achieved only at mantle depths. The classical idea that continents are too buoyant to subduct has given way to the notion of density changes driving deep subduction during the collision process, thus enabling some crust to be exhumed to the surface and the rest to sink into the mantle.
Continental Crust At Mantle Depths
August 2013, Vol. 9, No. 4
The discovery of diamond and coesite in crustal rocks is compelling evidence that continental material has experienced pressures that can be achieved only at mantle depths. The classical idea that continents are too buoyant to subduct has given way to the notion of density changes driving deep subduction during the collision process, thus enabling some crust to be exhumed to the surface and the rest to sink into the mantle. Over twenty localities of unequivocal continental crust containing diamond or coesite are now recognized around the globe, and their study constitutes a new field in petrology, dubbed ultrahigh-pressure metamorphism. Using microscopic observations, phase equilibrium modeling, geochronology, and geodynamic modeling, we track the journey of ultrahigh-pressure rocks to the mantle and back. Continental ultrahigh-pressure terranes impact our understanding of plate tectonics through time, crustal recycling and mantle geochemistry, melting in subduction zones, and collisional processes in general.
