Temperature dependence of Zr in rutile: empirical calibration of a rutile thermometer
Rutile is an important carrier of high field strength elements (HFSE; Zr, Nb, Mo, Sn, Sb, Hf,
Ta, W). Its Zr content is buffered in systems with quartz and zircon as coexisting phases. The …

Exhumation processes in oceanic and continental subduction contexts: a review
Although the exhumation of high pressure (HP) and ultrahigh pressure (UHP) rocks is an
integral process in subduction, it is a transient process, likely taking place during the …
