Organic carbon-rich sediments are globally developed in pelagic sedimentary sequences of
Aptian-Albian and Cenomanian-Turonian age. They formed in a variety of paleo-…

Correlation of the δ 13 C spike with the well dated occurrences of strata rich in organic
carbon detailed in Schlanger et al. (this volume), indicates that a global episode of intense …

Marine strata deposited during late Cenomanian and early Turonian time display lithological,
faunal, and geochemical characteristics which indicate that significant parts of the world …

The Cretaceous is characterized by unusually widespread distribution of “black shales”--
sequences of variable lithology containing numerous beds with organic-carbon (OC) contents …

Large amounts of organic carbon were deposited and preserved in marine sediments of late
Barremian through middle Albian and late Cenomanian-early Turanian age owing to the …

The stratigraphic record from both deep‐sea and shallow‐water depositional environments
indicates that during late Aptian through Cenomanian time (1) global climates were …

Normal marine deposition in the early Aptian was interrupted by an episode of ocean-wide
dysoxia/anoxia. This event is recorded by the occurrence of organic carbon-rich sediments in …

Recovery of long sequences of cores, at Deep Sea Drilling Project sites, from Recent to
Upper Jurassic pelagic ooze‐chalk‐limestone sections has shown that in general lithification …

New biostratigraphic data suggest, for the first time, that the long Aptian-Albian Oceanic
Anoxic Event was marked by at least three distinct, relatively brief episodes of widespread …

The dominance of volcanic processes and the importance of vertical tectonics in the geological
evolution of the Pacific Basin has been recognised since the time of Charles Darwin. …
