| Abstract: | The abundant conodonts were first found in Xihanshui Group of Western Qinling Mountains.According to their erect distributions of total 31 genera,98 species and 2120 elements,six conodont zones(varcus zone,hermanni-cristatus zone,disparilis zone,asymmetricus zone,trangularis zone and gigas zone)are set up in the stratigraphy,and thereby the age of Xihanshui Group should be Middle to Late Devonian. |
