Internally generated, or autogenic, terrestrial and marine sediment-transport dynamics can produce depositional patterns similar to those associated with climatic, tectonic, or sea level changes. A central challenge in accurately interpreting the sedimentary archive is determining what scales and types of deposits reflect autogenic controls on sedimentation in different environments. Autogenic sediment-transport dynamics commonly result from intermittent sediment storage in transient landforms, which produces episodic, spatially discontinuous sedimentation across a basin. The transition from localized, variable sedimentation to even, basin-wide sedimentation marks the shift from stochastic landscape dynamics to deterministic deposition responding to the long-term balance between sediment supply and the creation of space to accommodate sediment. This threshold can be measured in a wide variety of stratigraphic successions and has important bearing on whether climatic, tectonic, or sea level signals can be ...

碎屑地层中的自生沉积

内部产生的或自生的、陆地和海洋沉积物输送动力学可以产生与气候、构造或海平面变化相关的沉积模式。准确解释沉积档案的一个核心挑战是确定沉积的规模和类型反映了不同环境中沉积的自生控制。自生沉积物运输动力学通常是由瞬态地貌中的间歇性沉积物储存引起的，这会产生跨盆地的偶发性、空间不连续沉积。从局部、可变沉积到均匀、全盆地沉积的转变标志着从随机景观动力学到确定性沉积的转变，以响应沉积物供应与创造容纳沉积物的空间之间的长期平衡。
