Abstract: Danba area has undergone multiperiod deformation, metamorphism and magmatism since Mesozoic time. Six belts of metamorphic facies have been established, i.e., the sillimanite, kyanite, staurolite, garnet, biotite and sericite-chlorite belts. Rb-Sr isochron ages for staurolite schist in kyanitc belt and plagio-amphibolite and metabasalt in garnet belt are 149.0±7.1 Ma, 160.0±13.0 Ma and 150.2± 2.4 Ma respectively. They are considered to represent the most principal ages of reginal dynamothermal metamorphic event in Danba area. With reference to available Re0chr0n0i0gical data, the metamorphic history in Danba area is also discussed.
