摘要：

Electron microprobe and petrographic data on tourmaline-rich assemblages, in addition to available data from fluid inclusions and geochronological studies, are used to model the early stage of hydrothermal metamorphism in the Larderello geothermal field, Italy. The studied mineral assemblages and available fluid inclusion data reveal close analogies between the deepest and hottest part of the Larderello geothermal system and quartz-tourmaline and K silicate alteration zones of porphyry tin and copper deposits. -from Authors
