Résumé

ETM2 event

Glauconitization

Nappe zone phosphorites

Northeastern Algeria

REE geochemistry

[Display omitted] •The studied phosphorites belong to the nappes’ zone of NE Algeria.•Phosphorites were XRF and ICP-MS analyzed for their chemistry.•Phosphorites are glauconite-, organic matter- and pyrite-rich deposits.•Phosphorites were most likely affected by the ETM events.
