A Look Back…50 Years: South Florida Sediment

A lasting paradigm in carbonate sedimentology is that “carbonates are born, not made,” a truism that distinguishes them from the siliciclastic relatives. Fifty years ago, a classic contribution by Swinchatt emphasized the impact of their distinct origins and characteristics of early alteration on composition and texture of sediment of the South Florida reef tract. The results illustrated the complex influences of seagrass, physical process, biological breakdown, and how they vary across this shelf margin. Swinchatt suggested that “interrelationships between various rates of production and breakdown may be extremely complex and their effect on the sediment difficult to evaluate…and that further investigation is needed.”
