磷灰石裂变径迹（AFT）数据是沿着马拉喀什高阿特拉斯的横断线获得的，以限制其构造热演化。 AFT年龄在212±15 Ma和20 ± 4 Ma之间变化。中新世早期的 AFT 时代伴随着从板块链中心部分开始的较长平均轨道长度，被解释为该区域主要反转的时间，并由于非洲板块和欧亚板块之间的相互作用引起的缩短而产生了地势。对南阿特拉斯断层带以南采集的样本进行的热模拟表明，存在中新世中晚期甚至更晚的冷却，这归因于与阿特拉斯山脉下方存在的热异常相关的链条隆起部分。
Apatite fission‐track (AFT) data have been obtained along a traverse across the Marrakech High Atlas to constrain its tectono‐thermal evolution. AFT ages vary between 212 ± 15 Ma and 20 ± 4 Ma. An Early Miocene AFT age accompanied by long mean track length from the central part of the chain has been interpreted as the timing of the main inversion of this region with the creation of relief because of the shortening induced by the interplay between the African and Eurasian plates. Thermal modelling of samples collected south of the South Atlas Fault Zone indicates a Middle‐Late Miocene or even later cooling that has been attributed to the component of the uplift of the chain related to the thermal anomaly present beneath the Atlas Mountains.
