Paleogeographic reconstruction of an evolving foreland basin: developing a high-resolution perspective of the initial uplift of the Canadian rocky mountains

位于艾伯塔省和不列颠哥伦比亚省的加拿大西部沉积盆地是世界上最典型的前陆盆地之一。由于前陆盆地是相邻山脉抬升过程中克拉通负荷形成的地形凹陷，通过对其沉积岩层的分析，可以推断出造山史。在加拿大西部，虽然已经建立了地层变化和山脉隆起之间的一般关系，但沉积特征和初始隆起的详细相关性还没有得到很好的研究，这为理解山脉隆起的时间、与隆起有关的地层变化以及隆起与矿床形成(如碳氢化合物)的关系提供了巨大的潜力。因此，本研究旨在解开距今1.46亿-2亿年前的侏罗纪时期落基山脉的原始地形发育记录。将制作地理景观重建图，说明该地区如何随着山脉的上升而演变，并开始为沿海地区提供大量的沉淀物。

One of the classic foreland basins of the world is the Western Canada Sedimentary Basin in Alberta and British Columbia. As foreland basins are topographic depressions formed by the loading of a craton during elevation of an adjacent mountain range, by analyzing their sedimentary rock layers, the history of mountain formation can be deduced. In western Canada, although general relationships between stratigraphic changes and mountain uplift are established, the detailed correlations of sedimentary features and initial uplift are not well studied and offer significant potential to understand the timing of mountain uplift, stratigraphic changes associated with uplift, and the relationship of uplift to mineral deposit formation (e.g., hydrocarbons). Accordingly, this research aims to unravel the record of initial topographic development of the Rocky Mountains in the Jurassic Period, 146-200 million years ago. Geographic landscape reconstructions illustrating how the region evolved as mountains rose and began contributing significant sediment volumes to the foreland will be produced.
