In terms of world resources, Morocco is the largest holder and producer of sedimentary phosphates, with reserves estimated to represent about ~70–76% of world reserves (e.g., Jasinski, 2016, Jasinski, 2019, Pufahl and Groat, 2017; ). However, Morocco also bears igneous phosphate ores, especially in the High-Atlas mountain range.
