Paleogene magnetic stratigraphy in Umbrian pelagic carbonate rocks: The Contessa sections, Gubbio
The Umbrian sequence of pelagic carbonate rocks provides an opportunity for precise correlation between Paleogene biostratigraphy and geomagnetic polarity history. The red-to-pink, Paleocene to
Mass Mortality and Its Environmental and Evolutionary Consequences
TLDR
The data indicate that at the end of Cretaceous, when a high proportion of the ocean's planktic organisms were eliminated, an associated reduction in productivity led to a partial transfer of dissolved carbon dioxide from the oceans to the atmosphere, which resulted in a large increase of the atmospheric carbon dioxide during the next 50,000 years, which is believed to have caused a temperature rise revealed by the oxygen-isotope data.
Albian to Pleistocene Calcareous Nannofossils from the Western South Atlantic, DSDP Leg 39
Calcareous nannofossils were obtained from all sites drilled on Leg 39 (Figure 1). Late Albian and Turonian through Pleistocene assemblages were studied. Preservation varies considerably, usually
44. CENOZOIC PALEOCEANOGRAPHY IN THE SOUTHWEST PACIFIC OCEAN, ANTARCTIC GLACIATION, AND THE DEVELOPMENT OF THE CIRCUM-ANTARCTIC CURRENT
Cenozoic deep-sea sedimentation in the southwest Pacific area was controlled by large changes in the patterns of bottom-water circulation and erosion. The circulation patterns were largely controlled
Jurassic calcareous nannofossilbiostratigraphy of western Europe. Compilation of recent studies and calibration of bioevents
Renewed interest in Jurassic nannofossils over the past decade has significantly advanced understanding of taxonomy, evolution, and biostratigraphy. The diverse amount of new biostratigraphic
