Integrated stratigraphy across the Jurassic–Cretaceous boundary in the Rettenbacher section (Northern Calcareous Alps, Salzburg, Austria)
Rettenbacher Quarry carbonate sequence in the Northern Calcareous Alps represents highly dynamic pelagic carbonate sedimentation in the lower slope environment. The section spans from upper Tithonian Crassicollaria colomi Subzone to middle Berriasian Calpionella elliptica Subzone. Radiolarian samples belong to Pseudodictyomitra carpatica Zone. Considerable redeposition of calpionellids, organic walled dinoflagellate cysts, calcareous nannofossils and foraminifera in the allodapic layers, as well as extensive normal polarity remagnetisation event with substantial clockwise rotation is documented. Quantitative predominance of genera Watznaueria and Cyclagelosphaera indicate strong nannofossil modification during diagenesis. The almost straight trend in the δ13C with some slight carbon-isotope perturbations is recorded at Rettenbacher. Three significant and stratigraphically important negative excursions of the δ13Ccarb values were identified — including tentative indication of a new “Negative peak 4” in the upper part of the Elliptica Subzone — and correlated with other sections confirming stability, respectively isochronity within carbon chemostratigraphy.
期刊介绍:
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
