摘要：

有关传递带构造的讨论中,以下三个问题应引起重视:(1)褶皱冲断带中传递带(或称调节带)的概念和一般特征,传递带可定义为挤压构造变形中区域上保持缩短量守恒而产生的调节构造,它可以分为纵向和横向传递带两类,褶皱冲断带中分段构造的产生是通过走滑断层型式的横向传递带实现的;(2)伸展构造中传递带的概念和一般特征,裂谷系中传递带可定义为区域上为保持伸展量守恒而产生的传递或调节构造,它也可以分为纵向和横向传递带两类,裂谷系中分段构造的形成是通过横向凸起型式的横向传递带完成的;(3)传递带在沉积盆地内砂体发育的作用,砂体分布与传递带关系密切,一般是在对应横向传递带控制的地势低和河流入盆的地方,在陡坡和湖盆中心才能依次发育冲积扇-扇三角洲-浊积扇的砂体。

Abstract:

Three topics are discussed in this paper.(1)Concept and general characteristics of transfer zones in fold thrust zones.A transfer zone can be defined as an accommodation structure resulting from conservation of regional shortening strain during compressional deformation.It can be divided into two types:vertical and lateral transfer zones.Segmentation of fold thrust is realized by lateral transfer zone with the pattern of strike slip fault.(2)Concept and general characteristics of transfer zones in extensional tectonics.A transfer zone in a rift system can be defined as an accommodation structure resulting from conservation of regional extensional strain.It can also be divided into vertical and lateral transfer zones.Segmentation of rift system is realized by lateral transfer zone with the pattern of lateral uplift.(3)Function of transfer zones in development of sand bodies in sedimentary basins.Distribution of sand bodies is closely related with transfer zones.Sand bodies of alluvial fan,fan delta and turbidite fan can successively develop in the steep slope and in the center of lake basins that are corresponding to topographic lows and associated drainages controlled by lateral transfer zones.

Key words: transfer zone, fold trust zone, extensional structure, alluvial fan fan delta turbidite fan bodies
