| Summary: | Condensed associations of ammonites developed in carbonate epicontinental platforms show different preservational features in expanded deposits of shallow environments in relation to condensed deposits of deep environments. Recognizing these types of condensed associations is important when analysing the relationship between condensed sections and stratigraphical cycles. Deep condensed associations are a very good indicator of relative sea-level rises and transgressive trends. In contrast, shallow condensed associations provide an indicator of relative sea-level falls and regressive trends. [ZUSAMMENFASSUNG] kondensierte Assoziationen von Ammoniten auf epikontinentalen Karbonatplattformen zeigen bei Ablagerung unter Seichtwasserbedingungen verglichen mit Ablagerungen unter Tiefwasserbedingungen ein unterschiedliches Erhaltungsbild. Die Erfassung der Typen kondensierter Assoziationen ist bei der Analyse der Beziehung zwischen kondensierten Profilen und stratigraphischen Zyklen von Bedeutung. Assoziationen, die in großer Tiefe kondensiert sind, sind gute Indikatoren für relativen Meeresspiegelanstieg und transgressive Trends. Dagegen sind Seichtwasserassoziationen Anzeiger relativer Meeresspiegelabsenkungen und regressiver Trends. |
