一个一般的构造-沉积正演模拟方程是用来推导二维数值模型的沉积物的几何形状与发展中的断层弯曲和断层传播褶皱。这些样式的褶皱变形的速度模型，并与同构造侵蚀，运输和沉积。由此产生的二维数值模型模拟前生长和生长地层在海底和陆上设置。模型产生的几何形状和关系与自然例子中看到的大致相似。然而，复杂的地层几何形状可能会产生显着不同的那些产生以前的模型。对与断层弯曲褶皱和断层传播褶皱有关的生长地层进行了比较，并讨论了每种褶皱方式的特点。本文提出的正演模型具有预测能力，在可能的沉积物的几何形状与断层弯曲和断层传播褶皱，也在变形或侵蚀的一部分，结构可能已经经历了。
A general tectono-sedimentary forward modelling equation is used to derive two-dimensional numerical models of sediment geometries associated with developing fault-bend and fault-propagation folds. These styles of folding are described in terms of velocity models of deformation and are linked with syn-tectonic erosion, transport and sedimentation. The resultant two-dimensional numerical models simulate pre-growth and growth strata in both submarine and subaerial settings. The geometries and relationships produced by the models are broadly similar to those seen in natural examples. However, complex stratal geometries may be generated which are significantly different to those produced by previous models. Growth strata associated with fault-bend and fault-propagation folds are also compared and the distinguishing features of each mode of folding discussed. The forward models presented in this paper have predictive capabilities in terms of possible sediment geometries associated with fault-bend and fault-propagation folds and also in terms of the amount of deformation or erosion that a part of a structure may have undergone.
