Evidence of volcanic ash at a K-T boundary section: Ocean drilling program hole 690 C, Maud Rise, Weddell Sea off East Antarctica [PDF]

Rare vitric volcanogenic ash but more abundant clay minerals considered volcanogenic in origin are associated with an expanded and essentially complete K-T boundary sequence from Ocean Drilling Project (ODP) Hole 690 C on Maud Rise in the Weddell Sea off

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 ...

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.
