Recently, attention is called to the geological and petrological problems on the Hida metamorphic complex. Among them, the problem whether the complex was produced by a single metamorphism in late Palaeozoic period, or by polymetamorphism in pre-Silurian, probably Precambrian, and late Palaeozoic periods is in hot dispute. In the last three years, researches on the Hida metamorphic complex have made a remarkable progress, especially on the following three points. (1) During these three years, several geologists have surveyed jointly in the Hida metamorphic terrane and have discussed frankly on the field evidences of polymetamorphism. As the result of their field survey and discussion, several significant view-points have been shown. (2) During these years, some original works contributing to petrology as well as geology of the Hida metamorphic complex have been performed. (3) By introducing the dating methods based on radioactive decay, reliable age data on minerals and rocks in the complex have been accumulated, especially since 1967. A review of the above researches on polymetamorphism in the Hida metamorphic complex during the last three years is given in this paper.
