摘　　要：通过对道县虎子岩碱性玄武岩中片麻岩包体的岩石化学、Ｎｄ同位素模式年龄ＴＤＭ和颗粒锆石Ｕ－Ｐｂ法测年结果，确定了本区片麻岩包体的变质反应、变质相和原岩类型。Metamorphic change and facies, types of protolith on gneiss xenoliths in Mesozoic basalts in Huziyan, Daoxian region have been determined based on data from petrochemistry, Nd model age and U Pb dating of zircons. In addition, the authors have also reconstructed the formation and evolution of the studied region during pre-Cambrian.
