A review of the compositional features of Tunisia, Algeria, and Morocco phosphorites is
proposed in order to assess and compare the paleoenvironmental conditions that promoted …

Abstract “Old phosphorite” deposits (Ediacaran to early Cambrian) located in Central
Guizhou, South China, are hosted in carbonate and represent the earliest phosphogenesis …

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 …

The Algerian sedimentary phosphorites of marine origin are located mainly in the Tébessa
region, which is part of the Eastern Saharan Atlas. These phosphorites are hosted by …

Phosphate rock bears both geologically and environmentally significant information. Rare
earth elements and yttrium (ie, REY) characteristics have been commonly used for …

The marine environment in the Gulf of Gabes (southern Tunisia) is severely impacted by
phosphate industries. Nowadays, three localities, Sfax, Skhira and Gabes produce …

Intra-bone rare earth element (REE) fractionation trends were studied by LA-ICPMS analysis
to put constraints on (1) the mechanisms controlling REE fractionation within fossil bones;(2) …

Fossil bones and teeth are potentially important repository for geochemical proxy data and a
target for radiometric dating. The concentration of many trace elements in bones and teeth …

Abstract The Late Paleocene–Early Eocene phosphorites of the Metlaoui Group in Tunisia
are a world-class phosphate resource. We review the characteristics of phosphorites …
