Tébessa phosphates

Tébessa Province, Algérie

OtherP

Type
Marine sedimentary phosphorite (carbonate fluorapatite)

Phosphate rocks studied by Hill et al. (2024) to reconstruct redox conditions and diagenesis: U, Sr and rare earths carried by carbonate fluorapatite; samples taken at mines or from the Julius Kühn Institute archives. Early Eocene (about 55 Ma); Table S2 gives Algiers for two samples, Table S1 Tébessa, kept here. Coordinates not given.
