| Geochemistry of Basic Dykes in Wudang Block and Its Tectonic Significance |

| 摘 要： | Geochemical characteristics of the Neoproterozoic basic dykes widely exposed in the Wudang block of South Qinling show that the dykes possess the characteristics of continental tholeiitic basalts and were formed in a setting of continental rifting.Therefore,there was an ancient continental block in the areas of southern Qinling and Yangtze block during the Jinning period,and an important firting event of this ancient block occurred in the Early Neoproterozoic.

| Abstract: | Geochemical characteristics of the Neoproterozoic basic dykes widely exposed in the Wudang block of South Qinling show that the dykes possess the characteristics of continental tholeiitic basalts and were formed in a setting of continental rifting. Therefore, there was an ancient continental block in the areas of southern Qinling and Yangtze block during the Jinning period, and an important rifting event of this ancient block occurred in the Early Neoproterozoic. |
