| 摘 要： | 调节带和转换事是一种重要的构造现象，近年已逐渐爱到重视。由于大多数正断层体系都终止于调节带或转换带，使其成为产生区域公段的主因。转换带是平行于拉张方向具走滑和斜滑断层作用的不连续带；调节带是多个断层叠覆终止的区带。对不同伸民区和被动力缘调节带和转换带几何形态和运动特征的总结认为，调节带和转换带中的变形方式不依赖于伸民规模。调节带和转换带不但控制地形起伏和沉积环境，而且对烃类及地下水的聚集亦有重要影

| Abstract: | Accomedation zones and transfer zones are important structural phenomena and they have been gradually appreciated recently. Most normal faults terminate in accomodation zones and transfer zones which are the main ream causing rngional segnentation of extended zone. The paper synthesizes the former classification and proposed a revised, nongenetic of accomodtion zones and transfer zones which can be subdivided according to their angle relationship with extended direction and the trend of faults system at their two ends, strike - slip direction etc. respectively. It suggests transfer sones are the discrete zones of strike - slip and oblique slip faulting that generally tend to parallel to extension direction, and accomedation zones are belts of overlapping fault terminations. A review of the geometry and kinematics of accomedation zones and transfer sones in variously extended continental provinces and passive continental margins reveals that the style of deformation within aforation zones and transfer zones is independent of the magnitude of extension. They define topogaphic relief and sedimental settings and play important roles in the accumulation of hydnybon and under water. |
