TEH TIME AND PETROCHEMICAL CHARACTERISTICS OF VOLCANICS OF ZHULONGGUAN GROUP IN ZOULANGNANSHAN,GANSU

Xu Xiaochun; Yue Shucang (Department of Resources and Environment Sciences,Hcfei University of Technology,Hefei 230009)  
The volcanic rocks of Zhulongguan group are mainly basic rocks which are older in formation time,and deeper in metamorphic degree in Zoulangnanshan.Gansu province.In this paper,thetime the volcanic rocks formed has been measured by using Sm- Nd isotope geochronology for the first time. And the space-time.distribution of the Zhulongguan Group and the volcanic rocks occurring in it has been further determined.The vlocanic rocks are poor in Potassium and rich in albite.The rock series are mainly thiloeiitic- and alkali-basaltic.The characteristics of the chemical petrology,the compositions of Nd isotope and the distribution of the volcanic rocks show that the rock-forming tectonic background was an intracontinental rift.
