In order to elucidate the factors controlling the metal type disseminated in hydrothermal deposits related to granitic rocks, the investigation was conducted for the Eastern, Central and Western belt granites in Thailand. Observation of rocks under the microscope, magnetic susceptibility measurement, chemical analyses of rocks and constituent minerals were carried out in this study. The most remarkable difference was found in the total Al content in biotite between the Eastern belt granite accompanied with Cu, Pb, Zn and Mo and the Central and Western belt granitic rocks accompanied with Sn and W. This result is concordant with that obtained for the granitic rocks in Japan and South Korea.In addition, element partitioning experiments between mineral and hydrothermal solution were conducted using monazite, xenotime, columbite, tantalite and alabandite. The partitioning behavior of rare earth elements and divalent cations in the hydrothermal process were elucidated experimentally.

为了阐明与花岗质岩石有关的热液矿床中金属类型浸染的控制因素，对泰国东、中、西部花岗岩带进行了调查。对岩石进行了显微镜观察、磁化率测定、岩石化学分析和组成矿物分析。东部带花岗岩中铜、铅、锌、钼与中西部带花岗岩中锡、钨的总铝含量差异最显著，这与日本、韩国花岗岩的结果一致。此外，还以独居石、xenotime、柱长石、钽矿和铝榴石为原料，进行了矿物与水热液的元素分配实验。实验研究了水热过程中稀土元素与二价阳离子的配分行为。
