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.”
