COLLABORATIVE RESEARCH: Evaluation of Tectonic and Eustatic Effects on Development of Stratal Patterns in a Foreland Basin: Cretaceous Blackhawk Formation

作为该项目的一部分进行的研究将提供有关前陆盆地演化的详细信息。在前陆盆地，海平面变化、逆冲扩展的变化和沉积物供应的变化影响着沉积过程。详细的野外资料收集加上前陆盆地演化过程的数值模拟将有助于限制对腹地和盆地发育的解释。对于这些复杂的环境，我们对构造、游动和沉积相互作用的理解目前是有限的。将理论建模应用于详细的数据集将提供重要的信息，可用于未来解释前陆盆地的地层格局。本研究的野外数据将收集于上白垩统黑鹰组，并将重点研究进积和海侵事件的地层记录。相对较短的模拟时间间隔（58万年）使本研究有别于以往的前陆盆地数值模拟研究。

Research conducted as part of this project will supply detailed information about the evolution of foreland basins. In foreland basins, sea level change, variations in thrust propagation and changes in sediment supply influence depositional processes. Collection of detailed field data coupled with numerical modeling of the processes active during foreland basin evolution will help constrain interpretations of hinterland and basin development. Our understanding of the interaction of tectonics, eustasy and sedimentation is currently limited for these complex environments. The application of theoretical modeling to a detailed data set will provide important information which can be used for future interpretation of stratal patterns in foreland basins. Field data for this study will be collected in the Upper Cretaceous Blackhawk Formation, and will focus on the stratigraphic record of progradational and transgressive events. The relatively short time interval modeled (580,000 years) distinguishes this study from previous numerical modeling studies of foreland basins.
