Fig. 1. Holocene RSLR and associated mangrove development in far-field estuarine and intermediate-field calcareous settings.(A) Far-field estuarine
settings. (B) Intermediate-field calcareous settings. As the rate of RSLR decelerated, development of organic-rich mangrove sediments was initiated, which facilitated
maintenance of vertical position with respect to sea level, forming extensive mangrove forests. When RSLR stabilizes, ongoing sedimentation infills estuaries, building
deltas and replacing mangrove with freshwater wetlands, terrestrial forest, or saltpan, depending on climatic setting. CI, credible interval.
