A comparison of the Jurassic granitoids between the Hida belt and South Korea has been made utilizing the REE(rare earth element) pattems, initial Sr ratios, and types of granitoids.From the data, it will be seen that similarities and dissimilarities of the Jurassic granitoids between two regions. These are: 1) The modal composition of the Jurassic granitoids are similar between the two regions; 2) the radiometric ages of the Jurassic granitoids in the Hida belt are a little older than the ages of the Jurassic granitoids in South Korea; 3) the types, initial strontium ratios, and REE patterns of the Jurassic granitoids are different.These facts mean that source materials and genesis of the Jurassic granitoids between two regions were different. Although it is still immature to conclude the geological relations of the Jurassic granitoids between the two regions, from the difference in the initial strontium ratios between the two regions, it is suggested that the Jurassic granitoids in South Korea may have been situated in the continental side compared with the Jurassic granitoids in the Hida belt.

本文利用稀土元素模式、初始Sr比值和花岗岩类类型等资料，对韩国和希达带侏罗纪花岗岩类进行了对比，从中可以看出两地区侏罗纪花岗岩类的异同。这些是：2）希达带侏罗纪花岗岩类的放射性年龄比韩国侏罗纪花岗岩类的年龄稍老; 3）锶的类型、初始锶比、两地区侏罗纪花岗岩类的源区物质和成因存在差异是不一样的虽然目前对两个地区侏罗纪花岗岩类的地质关系的总结还不成熟，但从两个地区的初始锶比值的差异来看，与希达带的侏罗纪花岗岩类相比，韩国侏罗纪花岗岩类可能位于大陆一侧。
