Selective transportAbstract
Tropical marine carbonate systems have traditionally been interpreted using sediment transport models largely derived from siliciclastic environments, often assuming conservative sediment behaviour. This paper proposes an alternative perspective by demonstrating that carbonate transport operates as a selective and non-conservative process, in which biogenic, morphological and geochemical grain properties control mobilization thresholds, redistribution and sediment loss. Based on an integrated processual synthesis, we examine how hydrodynamic intermittency, fragmentation, syndepositional dissolution and differential export influence sediment budgets and selective preservation. Transport is interpreted as a dynamic filter that determines the fraction of produced sediment ultimately preserved in the stratigraphic record. By repositioning transport at the centre of analysis, this study complements previous work on carbonate production and depositional architecture, consolidating an integrated framework for understanding tropical marine carbonate systems.
