Abstract: There are some metaphoric rocks such as amphibolite, genesis, schist and marble exposed in Daqu Island of Zhoushan Is-lands, Zhejiang Province. In the past, they are assigned to Chencai Formation. Nevertheless, new LA-ICP-MS zircon U-Pb analysis yielded the ages of metamorphic neogenic zircon and metamorphic rim in biotite-plagioclase gneiss ranging from 260Ma to 270Ma, whereas the metamorphic age of marble and the formation age of undeformed pegmatite veins which intruded into metamorphic rocks are 261.1±1.3Ma and 258.0±1.6Ma respectively, indicating that the metamorphic age of the rocks in Daqu Island is~260Ma. This is the first reported Permian metamorphic rock on the northeastern margin of South China Block, which may provide some im-portant new information for Dongwu movement in South China, global Hercynian movement and even the Pangaea reconstruction.
