Environmental changes during marl-limestone formation: evidence from the Gargasian (Middle Aptian) of La Marcouline Quarry (Cassis, SE France)

, 2007
International audienceLimestone-marl alternations are usually interpreted to reflect cyclic paleoenvironmental fluctuations linked to Milankovitch-scale climate variations.

Case studies of Mesozoic calcareous nannofossils : implications for palaeoecology, calcareous nannofossil morphology and carbonate accumulation

, 2004
Kalkige Nannofossilien (KN) stellen seit dem Mesozoikum eine wichtige Komponente des marinen Phytoplanktons dar. Sie lassen sich zur Datierung mariner Sedimente und als paläoozeanografische Proxies nutzen. Die Ziele dieser Arbeit sind es, das Verständnis von Wechseln in den KN-Vergesellschaftungen (KNV) und von der Größenvariabilität einzelner Taxa im ...
