In geodynamically active areas, spatio-temporal variations in rock uplift can provide key insights into the processes responsible for the evolution of topography. The Central Anatolian Plateau (CAP) southern margin experienced a rapid rock-uplift pulse with maximum rates of 3.5 m/kyr during the Quaternary, based on marine sediments dated to the middle Pleistocene that are now located at 1,500 m.a.s.l. Fluvial landscapes record elements that reflect temporal and spatial variations in rock-uplift rates, such as the normalized river steepness index, which is affected by rock-uplift rate, the erodibility of the underlying rock, and climate. Following the calibration of river profiles for an erosion coefficient value, which can be done using independent data (in our case, uplifted marine terraces and dated marine sediments), river profiles can be inverted for the rock-uplift histories that created them. Here, we demonstrate how it is possible to define the spatio-temporal rock-uplift history of the CAP southern margin by quantitative analysis of river profiles.

安纳托利亚高原中部南缘河流剖面反转引起的岩石隆起的时空变化

在地球动力学活动区，岩石隆起的时空变化可以提供对负责地形演化过程的关键见解。中部安纳托利亚高原 (CAP) 南缘在第四纪经历了最大速率为 3.5 m/kyr 的快速岩石隆起脉冲，基于可追溯到中更新世的海洋沉积物，现在位于 1,500 masl 河流景观记录了反映元素岩石隆起速率的时空变化，例如受岩石隆起速率、下伏岩石可蚀性和气候影响的归一化河流陡度指数。在针对侵蚀系数值校准河流剖面之后，这可以使用独立数据（在我们的例子中，隆起的海洋阶地和年代久远的海洋沉积物）来完成，河流剖面可以根据形成它们的岩石隆起历史进行倒置。在这里，我们展示了如何通过河流剖面的定量分析来定义 CAP 南缘的时空岩石隆起历史。
