Kurzfassung
Die Analyse von Wachstumsstreifen in diagenetisch veränderten Scleractiniern ist stets mit der Problematik konfrontiert, daß durch die unterschiedlichen Möglichkeiten der Umwandlung des Skelett-Aragonits in Kalzit diese Information meistens verloren geht. Einzige Ausnahmen stellen die Lösung des Aragonits und die zeitgleiche Ausfällung des Kalzits dar, wobei keine Lösungsporosität entsteht. Beispiele dieses Diagenesemusters werden aus dem Pleistozän der Insel Barbados beschrieben.
Abstract
Growth line analysis of diagenetically altered scleractinians is only possible if carbonate diagenesis has followed the pathway of aragonite leaching and coeval formation of low magnesium calcite. All other possibilities of aragonite transformation into calcite exclude the preservation of this growth line banding. Examples of these diagenetic patterns are found in the Pleistocene of Barbados.
