摘要
滑脱构造是地壳内广泛发育的一种构造现象,它的形成与演化过程贯穿在地壳演化的整个进程之中。本文就滑脱构造的演化过程及动力学,运动学机制进行了初步探讨,并提出了二个可能的演化模式和二个理论模型—前陆褶皱带滑脱构造的运动学模型与壳内低速层中反向流导致的大规模滑脱构造的动力学模型。
The decollement is discovered generally existing within the crust.Its form- ation and evolution run through the entire history of the crustal evolution.This paporis focused on the discussion of the evolutional process of docollemet. Its dynamic mechanism and kinetic mechanism. Two possible evolutional patterns and two theoretical models are put forward. They are kinetic model of decol- lemet in foreland fold belt and dynamic model of decollement resulting from antithetic matter flow in lowveloclty zone of the crust.
