The importance of rare earth elements (REEs) in high-tech industries has triggered a global
struggle to find new resources. Sedimentary phosphorites are one of the major holders of …

Rare earth elements and yttrium (REY) have gained greater attention for being largely used
in various high-tech applications and green energies. Recently, supply shortage and high …

Abstract The Upper Cretaceous-Paleogene sedimentary series of the High Atlas hosts
underexplored phosphate-rich sediments and presents an excellent example of how …

The Tethyan phosphates were formed during the Upper Cretaceous and Eocene interval as
a result of the collision of the African–Arabian and Eurasian plates and the closing of the …

This study is focused on the environmental geochemistry of potentially toxic metals (PTMs)-
