Abstract In this study, we propose a geodynamic model covering sedimentation, metamorphism, magmatism, and exhumation processes for the western North Patagonian Massif basement. The youngest detrital zircon population ages (ca. 369 ± 8 Ma) obtained in a schist sample constrains the sedimentation stage to the Carboniferous Period. A first prograde metamorphic stage (M1-D1) produced the main foliation (S1) under greenschist conditions (~ 500 °C;

北巴塔哥尼亚地块西部晚古生代地球动力学演化及其沿冈瓦纳大陆西南边缘的构造背景

摘要 在这项研究中，我们提出了一个涵盖北巴塔哥尼亚地块西部基底的沉积、变质、岩浆作用和折返过程的地球动力学模型。在片岩样品中获得的最年轻的碎屑锆石群年龄 (ca. 369 ± 8 Ma) 将沉积阶段限制在石炭纪。第一个顺行变质阶段 (M1-D1) 在绿片岩条件下 (~ 500 °C;
