Journal ArticleDOI
U/Pb zircon ages constrain the architecture of the ultrahigh-pressure Qinling–Dabie Orogen, China
TL;DR: In this article, new SHRIMP and TIMS zircon ages, 40Ar/39Ar ages, and eclogite locations contribute significantly to our understanding of the ultrahigh-pressure Dabie Shan.
Journal ArticleDOI
Subduction factory 1. Theoretical mineralogy, densities, seismic wave speeds, and H 2 O contents
TL;DR: In this paper, the authors present a new compilation of physical properties of minerals relevant to subduction zones and new phase diagrams for mid-ocean ridge basalt, lherzolite, depleted LH, harzburgite, and serpentinite.
Journal ArticleDOI
Subduction factory 2. Are intermediate-depth earthquakes in subducting slabs linked to metamorphic dehydration reactions?
TL;DR: In this paper, the authors used thermal-petrologic models of subduction zones to test the hypothesis that intermediate-depth intraslab earthquakes are linked to metamorphic dehydration reactions in the subducting oceanic crust and mantle.
Journal ArticleDOI
Tectonics of the Qinling (Central China): tectonostratigraphy, geochronology, and deformation history

TL;DR: The Qinling orogen preserves a record of late mid-Proterozoic to Cenozoic tectonism in central China as mentioned in this paper, where high pressure metamorphism and ophiolite emplacement assembled the Yangtze craton, including the lower Qinling unit, into Rodinia during the ∼1.0 Ga Grenvillian orogeny.
Journal ArticleDOI
Subduction factory: 4. Depth-dependent flux of H2O from subducting slabs worldwide
TL;DR: In this article, a global compilation of the thermal structure of subduction zones is used to predict the metamorphic facies and H 2 O content of downgoing slabs.
