Fission track study has been conducted on the miarolitic garnet from Zhangzhou Igneous Complex. It is found that the garnet is of Mn- and Fe-rich type; its uranium concentration ranges from 0.2 to 0.8 mu g/g, with an average of 0.7 mu g/g; fission track age of the garnet is 73.4 +/- 2.8 Ma; and induced fission track length and spontaneous fission track length are 11.5 +/- 0.7 mu m and 11.0 +/- 0.8 mu m, respectively. These data were used to constrain evolution of the granite body.
