| Abstract: | Based on the geological, petrological, geochemical and geochronological data of the East Qinling-Dabie Mountains, the present paper discusses the metamorphic and magmatic events in the East Qinling-Dabie Mountains, their geochronology and tectonic background. The geochronological framework is established for metamorphic and magmatic events since Proterozoic, and a geological map with age data of magmatic and metamorphic events in the East Qinling-Dabie Mountains is compiled. |
| Keywords: | Geochronology Tectonic background Metamorphic event Magmatic event East Qinling-Dabie Mountains |
