The composition of the continental crust - ScienceDirect

Apr 01, 1995 The excess of Zr and Hf was caused by the temperature dependent extraction of these elements by the tonalitic melts from their mafic source. An average concen- tration of 200 ppm Zr in the continental crust indicates tem- peratures of partial melting not far from 850. (Watson and Harrison, 1983).
