Abstract
The High Atlas range in Morocco is characterised by extensive outcrop of Paleozoic, Triassic and Jurassic rocks, with very restricted occurrences of younger rocks in the central part of the range. Besides, evidence suggests that a relatively thick succession covered the whole area prior to the Late Cretaceous-Cenozoic inversion of the Atlas Rift and the development of this anomalously high intracontinental range. This process has been studied in the Marrakech and Central High Atlas using numerical models based on zircon (U-Th)/He thermochronometry and reflectance vitrinite data. Results have been addressed by the recently published works:

These works will be present by their main authors and later discussed focusing on their implications on the quantification of the vertical movements in the Moroccan High Atlas.
