| Abstract: | In this paper, we present new isotopic (H, O) data of fluids in tourmalines from the large Sn deposit at Solnechnoye (Far East Russia). These data indicate that the deposit formed by fluid‐rock interactions in a hydrothermal system where the mineralizing fluid was mainly magmatic and to a lesser extent meteoric. This is in agreement with a magmatic fluid model. Our interpretation of the new isotopic data is consistent with earlier findings of the studies on fluid‐rock interactions that magmatic fluids form larger Sn deposits than exogenic fluids. We propose that isotopic (H, O) data of fluids in tourmaline, rather than those in quartz, muscovite, or chlorite, support robust interpretation on the nature of mineralizing fluids associated with Sn deposits. |
