Microborer ichnocoenoses in Quaternary corals from New Caledonia: reconstructions of paleo-water depths and reef growth strategies in relation to environmental changes

► Paleodepth reconstructions based on microendolith and coralgal assemblages in Quaternary reefs from New Caledonia. ► Microendoliths provide better accuracy than coralgal assemblages especially in the 0-10 m bathymetric range. ► Evidence for rapid environmental changes and small sea-level variations of about 2-5 m ► Evidence of a shallowing-upward trend corresponding to a catch-up reef growth during Holocene. ► A paleodepth envelope based on microendolith assemblage analysis proposed for Kendec Holocene reef.
