“…Besides, based on the Sr age of 22 Ma for limestone D10_003, as discussed below, the summit of RGR was likely shallower at the time of calcite cementation. Finally, a relatively strong bottom current (50 cm s −1 ) at the RGR seafloor (Harlamov et al., 2015; Lisniowski et al., 2017) would facilitate seafloor carbonate cementation and hardground formation because the vigorous bottom currents enhance diffusion and the exhumation of lithified carbonates, and prevent fine‐grained sedimentation (Noé et al., 2006). As a result, the decreased porosity and permeability of the lithified limestone may have prevented or minimized phosphatization, which contrasts with the unconsolidated pelagic sediment in which phosphatization was facilitated by high porosity and permeability.…”

“…suggesting possible events occurring within the CSR and its vicinities are those of Harlamov et al (2015) and Lisniowski et al (2017). These suggest the presence of internal waves at the site.…”
