Apatite in marine sediments is generally thought to have formed during early diagenesis (Ruttenberg, 2003). Sediment pore-water profiles indicate that apatite (as carbonate fluorapatite) starts to precipitate immediately below the seafloor, tied to the remineralization of organic matter, which increases pore-water phosphate concentrations.
