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 …

The carbon budget of crustal reworking during continental collision: Clues from nanorocks and fluid inclusions
The source of volatiles in the continental crust is a long-standing issue. In addition to
controlling the amount of melt generated during anatexis, H 2 O and CO 2 budgets of the …
