Geochemistry of metasedimentary restitic rocks and implications for melting conditions and metal potential of crustal felsic magmas
Partial melting of crustal rocks, also known as anatexis, is the major mechanism of the
fractionation of the continental crust and generation of felsic melts. The segregation of melts …
