Collaborative Research: Reconstructing ancient passive margin dynamics by relating geomorphic and stratigraphic surfaces: a combined laboratory and field study

已提供资金，对描述被动大陆边地层结构及其与地貌表面的关系的统计数据进行实验室和实地调查。该项目的总体目标是提高我们反演古地表动力学和地形的地层记录的能力。大陆边的记录包含沙洲、水道和水道网等特征，但我们无法精确地重建这些保存下来的矿床与产生这些矿床的地貌过程之间的关系。因此，研究计划是使用水槽模型来测量和识别渠化，分布式系统的缩放关系，重点是三角洲和深水系统。目标是确定地层不连续面是如何形成的，并看看是否可以从表面形态的统计描述中推导出形成机制。最终的目标是能够推断出的动态起源的侵蚀表面，使用来自实验水槽模型的关系。所述的更广泛的影响，包括学生培训。这项工作也有实际价值，在了解沿海系统如何增长，以及在从三角洲和深水系统的资源提取。这些结果可能对我们如何解释野外地层表面具有重要意义。

Funds are provided to carry out a lab and field investigation of statistics describing the stratigraphic architecture of passive continental margins and their relationship to geomorphic surfaces. The overall objective of the project is to improve our ability to invert the stratigraphic record for paleo surfaces dynamics and topography. The continental margin record contains features such as bars, channels and channel networks, yet we cannot precisely reconstruct the relationship between these preserved deposits and geomorphic processes that produce them. Thus, the research plan is to use flume models to measure and identify scaling relationships in channelized, distributive systems with a focus on deltaic and deep water systems. The goal is determine how stratigraphic discontinuities are formed and to see if the mechanism of formation can be deduced from statistical descriptions of surface morphology. The ultimate objective is be able to infer the dynamic origin of fossilized erosional surfaces, using relationships derived from the experimental flume models.The stated broader impacts include student training. The work also has practical value in understanding how coastal systems grow, as well as in resource extraction from the deltaic and deep-water systems. The results could have important implications in how we interpret stratigraphic surfaces in the field.
