- 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. Late Campanian (about 73 Ma). Coordinates not given.
