摘　　要：文中报导了1988年10月在日本岛根大学召开的第五届IGCP-220项目工作总结及学术讨论会“东南亚与西太平洋地区锡—钨花岗岩资源评价及对比”课题研究取得的新进展如“地体、碎块、岩带、花岗岩系列与金属成矿区的关系”。“稀有金属花岗岩”。“氧化型与还原型锡—钨矽卡岩矿床以及岩浆体系的氧逸度”,“成矿溶液的性质及其放射性(?)(?)同位素的研究”。“全岩及其单粒副矿物的稀土配分的研究”及“花岗岩填图”The 5th International Conference of IGCP-220 project on 'Correlation and resource evaluation of tin tungsten granites in Southeast Asia and the western pacific region ' was held in Matsue, Japan. October 17-19, 1988. From the papers presented in the conference some interesting topics are selected, summarized and commented in the present article by the author. They are'The relationship of terrain.segment, granite series with metallogenetic province associated with species of ore deposits' , “aremetal granites', ' Oxidized and reduced skarn Sn-W deposits and fugacity of magma system' .' The nature of ore fluids and isotopic study of radiogenic tracers', 'Whole rock REE pattern and REE microanalysis for single grain of accessory minerals in rocks' , ' Granite mapping ' etc as well as 'The classification of granites and the model of its origination' reviewed by the author.
