Partitioning of Nb and Ta between rutile and felsic melt and the fractionation of Nb/Ta during partial melting of hydrous metabasalt
In order to fully assess the role of rutile in fractionation of Nb/Ta during partial melting of
hydrous metabasalt, we have measured rutile–felsic melt partition coefficients (D values) for …

Adakitic (tonalitic-trondhjemitic) magmas resulting from eclogite decompression and dehydration melting during exhumation in response to continental collision
Modern adakite or adakitic rocks are thought to result from partial melting of younger and
thus warmer subducting ocean crust in subduction zones, with the melt interacting with or …
