| 摘 要： | 通过晚侏罗世-早白垩世郯庐断裂带的应力场性质、盆地原型展布及构造环境分析,并结合同一时期大别造山带北缘火山岩主量元素、稀土元素的地球化学特征,认为大别造山带北缘和郯庐断裂带西侧区域为伸展构造环境,主张应力方向为北西西-南东东,郯庐断裂带在晚侏罗世-早白垩世应为右行平移伸展活动.

| Abstract: | According to the nature of stress field,the prototype exhibition of the basin,tectonic(setting) analysis and the geochemical features of principal elements,rare-earth elements in the volcanic rocks within the northern Dabieshan orogenic belt,the authors think that the Dabieshan orogenic belt and the western Tancheng-Lujiang fault zone are extension tectonic settings,and the stress orientation is NWW-SEE.The Tancheng-Lujiang fault zone is dextral strike slip extension from Late Jurassic to Early Cretaceous. |

| Keywords: | stress field geochemistry of volcanic rocks regional extension and pull-apart Dabieshan orogenic belt Tancheng-Lujiang fault zone |
