Abstract

Literature-based estimates of Mesozoic-Cenozoic shoalwater carbonate composition indicate important changes in frequency distribution of carbonate biota that translate into changes of bulk skeletal mineralogy of the original sediments. This mineralogy was strongly dominated by metastable carbonates during the Triassic (mainly aragonite) and during the Cenozoic (aragonite and magnesian calcite). [n between these periods lies an interval of reduced metastable carbonate and consequently high calcite content. This biogenic aragonite-calcite cycle parallels the one observed in (presumably inorganically precipitated) ooids and marine cements.
