The trace element content of single fluid inclusions in quartz from Tsushima granite in Japan was determined with particle-induced X-ray emission (PIXE) to investigate the chemical features of Ti in hydrothermal fluids derived from granites. Most of the fluid inclusions were polyphase and vapor-rich fluid inclusions, and both types contained Cl, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, Ge, Br, Rb, Sr, Ba, and Pb. Concentrations of Ti were of up to a few tens ppm wt Ti for polyphase inclusions and up to one hundred ppm for vapor-rich fluid inclusions. The Ti content indicated the possibility of transportation of a certain amount of Ti by granitic hydrothermal fluids.

利用粒子诱导X射线发射（PIXE）法测定了日本对马花岗岩中石英中单一流体夹杂物中的微量元素含量，以研究花岗岩中热液中Ti的化学特征。大部分流体夹杂物是多相和富蒸气流体夹杂物，两种类型都包含Cl，K，Ca，Ti，Mn，Fe，Ni，Cu，Zn，Ge，Br，Rb，Sr，Ba和Pb。对于多相夹杂物，Ti的浓度最高为几十ppm wt Ti，对于富含蒸气的流体夹杂物，最高为一百ppm wt。Ti含量表明，花岗岩热液有可能输送一定量的Ti。
