Current end-member models for the geodynamic evolution of orogenic plateaus predict (a) slow and steady rise during crustal shortening and ablative subduction (i.e., continuous removal) of the lower lithosphere or (b) rapid surface uplift following shortening, which is associated with punctuated removal of dense lower lithosphere and/or lower crustal flow. This review integrates results from recent studies of the modern lithospheric structure, geologic evolution, and surface uplift history of the Central Andean Plateau to evaluate the geodynamic processes involved in forming it. Comparison of the timing, magnitude, and distribution of shortening and surface uplift, in combination with other geologic evidence, highlights the pulsed nature of plateau growth. We discuss specific regions and time periods that show evidence for end-member geodynamic processes, including middle–late Miocene surface uplift of the southern Eastern Cordillera and Altiplano associated with shortening and ablative subduction, latest...

中部安第斯高原的构造演化及其对高原生长的意义

当前用于造山高原地球动力学演化的端元模型预测 (a) 在地壳缩短和下岩石圈烧蚀俯冲(即连续移除)期间缓慢而稳定地上升或 (b) 缩短后地表快速隆升,这与间断去除致密的低岩石圈和/或低地壳流。本综述综合了近期对中部安第斯高原现代岩石圈结构、地质演化和地表抬升历史的研究结果,以评估形成该高原所涉及的地球动力学过程。比较缩短和地表隆起的时间、幅度和分布,结合其他地质证据,突出了高原生长的脉冲性质。
