This research will integrate the fields of magnetostratigraphy, sedimentology, biostratigraphy and structural geology to analyze a latest Cretaceous to early Tertiary sedimentary basin, here termed the Axhandle Basin, that developed atop an active thrust sheet in central Utah. The analysis will define the geometry, sedimentation patterns and sedimentation rates of the basin during the time that shortening occurred on the underlying thrust system. As a result, the timing and shortening history of the thrust system may be interpreted and compared with similarly well dated tectonic analyogues such as those in the Tertiary of the Himalaya and Pyrenees. Understanding the tectonics and sedimentation of such basins will aid the search for hydrocarbon resources.

这项研究将整合以下领域： 磁性地层学、沉积学、生物地层学和 构造地质学分析了晚白垩世至早白垩世 第三纪沉积盆地，这里称为Axhandle盆地， 在犹他州中部的活动逆冲岩席顶部发育。 的 分析将确定几何形状、沉积模式和 在缩短的时间内盆地的沉积速率 发生在下伏的逆冲系统上 结果导致 推力系统的定时和缩短历史可以 解释并与类似的地质构造对比 如喜马拉雅第三纪的分析， 比利牛斯山 了解这种构造和沉积作用 盆地将有助于寻找油气资源。
