Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

Sedimentology, EarlyView.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.
