Geochronology and tectonic background of magmatic and metamorphic events in the East Qinling-Dabie Mountains

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.
