Controls on the incongruent release of hafnium during weathering of metamorphic and sedimentary catchments

Abstract:

It is well established that Hf weathers incongruently such that the isotopic compositions in seawater are offset from those of Nd relative to the correlation defined by bulk lithologies of the continental crust. Here we study this process in detail with new records of the seasonal variability of isotope compositions and concentrations of Hf and Nd in four Swiss rivers. The water has been filtered at a pore size of 0.45 μm and therefore represents the truly dissolved and the colloidal pool of ...
