Belemnite-based strontium, carbon and oxygen isotope stratigraphy of the type area of the Maastrichtian Stage [PDF]
Netherlands Journal of Geosciences - Geologie en Mijnbouw, 2011 AbstractBelemnitellid cephalopods from the Maastrichtian stratotype area (southeast Netherlands) are shown to be comparatively well preserved. Although partial diagenetic alteration has been observed, micromilling techniques have permitted the extraction of pristine belemnite calcite, suitable for the reconstruction of strontium (Sr), oxygen (O) and ...

Sequence stratigraphy of the Upper Miocene Stage IVC in the Labuan-Paisley Syncline, northwest Sabah Basin [PDF]
Bulletin of the Geological Society of Malaysia, 1997 A sequence stratigraphic study of the Upper Miocene Stage IVe has been carried out in the Labuan-Paisley Syncline, Northwest Sabah Basin with the aim of identifying new hydrocarbon plays in the study area. The Stage IVe contains up to 4,000 m thick, clastic sediments deposited in coastal plain to bathyal environments probably between 8.2 Ma and 10.5 Ma

Aspects of the stratigraphy and ammonite faunas of the Aalenian-Bajocian stages in Great Britain [PDF]
, 1980 A detailed stratigraphic revision of parts of the Aalenian-Bajocian Stages is undertaken. The status of the Sowerbyi zone is discussed and reasons given for its rejection and replacement by the Discites and Laeviuscula\ud Zones. The Sauzei Zone is redefined.

Sedimentary stratigraphy of Lake Chalco (Central Mexico) during its formative stages [PDF]
International Journal of Earth Sciences, 2021 Lake Chalco lies south of the Basin of Mexico and has been the subject of studies related to Late Quaternary climate variability. In 2016, the International Continental Scientific Drilling Program “MexiDrill Project” recovered a 520-m sediment record from Lake Chalco.
