U-Th-Ra fractionation during weathering and river transport
The potential of radioactive disequilibria as tracers and chronometers of weathering
processes has been recognised since the 1960's (eg, Rosholt et al. 1966; Hansen and Stout …

Crustal redistribution, crust–mantle recycling and Phanerozoic evolution of the continental crust
We here attempt a global scale mass balance of the continental crust during the
Phanerozoic and especially the Cenozoic (65Ma). Continental crust is mostly recycled back …
