江西庐山地区伸展构造与星子变质核杂岩

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、猪岭山滑来峰以及盖层内正断层组合、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。本文重点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和动力学特点以及形成时代和区域地质构造背景，探讨性地提出了“走—拉构造体制”。

EXTENSIONAL STRUCTURE AND THE XINGZI METAMORPHIC CORE COMPLEX IN THE LUSHAN AREA,JIANGXI

Extensional structure in the Lushan area,Jiangxi,is one of the typical systematic structural features of the Meso-Cenozoic structural deformation. It is characterized by vertical layering,lateral zoning and ordering of spatial structural organization. Among other things theXingzi polyphase composite metamorphic core complex, Fuchuanshan detachment window,Zhulingshan thrust outlier and normal fault grouping in covers and fossil Poyang Lake basinare the forms of manifestation of extensional structure in different spatial loci. This papermainly deals with the features of the above-mentioned representative structural forms,analyzes the kinematic and dynamic features of extensional deformation and the formation ageand regional tectonic setting in the area and puts forward an exploratory idea of the nstrikeextensional tectonic system".
