摘要
江西庐山地区的伸展构造，是中新生代时期构造变形具有典型特色的系统性构造形迹之一，具有垂向分层、方向分带、空间组合结构有序之特点。其中的星子多期复合变质核杂岩构造、浮船山拆离构造窗、猪岭山滑来峰与盖层内正断层组合及古鄱阳湖盆地等，分别是不同空间部位伸展构造的表现型式。本文着重阐述了上述代表性构造型式的特征，分析了区内伸展构造变形的运动学与动力学特点及形成时代和区域地质构造背景，探讨性地提出了“走—拉构造体系”。
The extensional structure in Luskan area,Jiangxi is one of systematicalstructural features with a typical characteristics of structural deformationduring the Mesozoic and Cenozoic periods.It is characterized by the ver-tical stratification, direction zoning and order of space composite textu-res,of which multicomposite metamorphic core complex structure in Xing-zi, manifold structural window(fenster)in Fuquanshan, klippe and thenormal fault assemblages within the cover in Zhulinshan as well as theold basin of Poyang lake. etc were presented as the types of extensionalstructure within the different space parts. This paper puts emphasis ondescribing the features of the above representative structural types,analy-zing the kemitics of extensional structural deformation within the ar-ea,the features of kemitics mechanics as well as the forming age and thestructural background of reginal geology,and puts forward a viewpointof “strking-strenching structural mechanics”.
