We identify two piercing point pairs along a ~500 km transect of the arcuate strike-slip Denali fault to document long-term slip partitioning. Geochemical and isotopic similarity between Foraker and Panorama-Schist Creek-Nenana Plutons suggest ~155 km of right-lateral displacement on the western Denali fault since 37 Ma at a rate of ~4.2 mm/year. The eastern Denali fault Maclaren-Cottonwood Terrane geochronology correlation establishes ~305 km of displacement on the eastern Denali fault since 33 Ma at a rate of ~9.2 mm/year. The ratio of Pleistocene-Holocene slip rates between the western (5.3 mm/year) and eastern (12.9 mm/year) Denali fault is 0.41 and our new constraints yield a Late Eocene-Holocene ratio of 0.46. Hence, we interpret that the overall arcuate geometry of the Denali fault master strand was established by 33 Ma. We infer that the persistent long-wave geometric stability of the Denali fault and other highly slip partitioned fault systems are related to long-term highly oblique transpressive environs.

长距离深成相关系表明沿德纳利断层发生了 3300 万年的应变划分

我们沿着弓形走滑德纳利断层的约 500 公里断面确定了两个穿刺点对，以记录长期滑动分区。Foraker 和 Panorama-Schist Creek-Nenana Plutons 之间的地球化学和同位素相似性表明，自 37 Ma 以来，西部 Denali 断层以约 4.2 毫米/年的速度发生了约 155 公里的右侧位移。东部 Denali 断层 Maclaren-Cottonwood Terrane 地质年代学相关性确定了东部 Denali 断层上自 33 Ma 以来以~9.2 毫米/年的速度发生~305 公里的位移。西部（5.3 毫米/年）和东部（12.9 毫米/年）德纳利断层之间更新世-全新世滑动速率的比率为 0.41，我们的新约束产生晚始新世-全新世比率为 0.46。因此，我们解释说 Denali 断层主链的整体弓形几何形状是在 33 Ma 建立的。
