Definition
Beach rock results from lithification of unconsolidated sediments by calcium carbonate cements in the tidal zone of mainly tropical and subtropical beaches. Aragonite and calcite, in a number of crystalline forms, are the primary agents of cementation. All kinds of beach sediments can be cemented, from fine sands to gravels of biogenic and/or terrigenous origin. Beach rocks can also vary greatly in texture and degree of lithification, some being quite porous and friable, others being dense and highly indurated. Beach rock takes on the disposition of the parent beach, including the preservation of beach slopes and stratigraphy. Outcrops usually show a number of distinct bands that represent the bedding planes, internal laminae, and sedimentary structures preserved during the cementing process which can be quite rapid.
Description
Beach rocks are a common and conspicuous feature of many island and mainland shores in reefal areas. They vary...
