Quantitative foraminiferal and palynomorph biostratigraphy of the Paleogene in the southwestern Barents Sea [PDF]

open access: yes, 2004
The stratigraphic distribution of both foraminifera and dinoflagellate cysts is recorded from the Paleocene to Eocene Torsk Formation in 12 petroleum exploration wells drilled in the southwestern Barents Sea.

Sedimentation of the Lower Cretaceous Xiagou formation and Its Response to Regional Tectonics in the Qingxi Sag, Jiuquan Basin, NW China [PDF]

open access: yes, 2014
Under the constraint of an isochronous sequence stratigraphic framework, sediment infill of the Xiagou Formation reflects the overall control of dynamic tectonic movements and episodic sedimentations in the Qingxi Sag.

The first finding of rodingites with a gold-palladium-platinum mineralization within the Sikhote-Alin

open access: yesЛитосфера, 2017
The subject of investigations were rodingites, whose outcrops were recently found inTaukha terrane of the Sikhote-Alin. The contents of the rock-forming oxides in rodingites were determined using the methods of chemical analysis as well as the gravimetry

TAXONOMY AND EVOLUTIONARY RELATIONSHIPS WITHIN THE CALCAREOUS NANNOFOSSIL GENUS ERICSONIA IN THE UPPER PALEOCENE

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2018
Detailed distribution ranges of the genus Ericsonia were obtained in the upper Paleocene interval from two deep-sea sections, ODP Site 1262 (South Eastern Atlantic Ocean) and Site 1215 (Eastern Equatorial Pacific Ocean), and were complemented with ...

Paleocene ostracoda from Nûgssuaq, West Greenland

open access: yesBulletin Grønlands Geologiske Undersøgelse, 1971
This paper is the first description of post-Palaeozoic ostracods from Greenland. The material was collected from the Paleocene (Danian) Agatdal Formation on Nûgssuaq, West Greenland, a formation which has yielded a huge fauna – over 600 species, mostly gastropods and pelecypods.

Rectoprotomarssonella n. gen., a new agglutinated foraminiferal genus from the Upper Cretaceous of the Carpathian Flysch [PDF]

open access: yes, 2007
The new agglutinated foraminiferal genus Rectoprotomarssonella n. gen. is characterized by its high trochospiral coiling with multiserial to uniserial chamber arrangement and solid, noncanaliculate wall with calcareous cement.

open access: yes, 1989
Deep marine, fine grained sedimentary strata of Maastrichtian through Miocene age in the Labrador and North Sea sedimentary basins are rich in agglutinated benthic foraminifera.

Late Paleocene event chronology; unconformities, not diachrony

open access: yesBulletin de la Société Géologique de France, 2000
Abstract The chronology of the events associated with the late Paleocene thermal maximum (LPTM, Chron C24r) has been established through the construction of a composite reference section that involved chemomagnetobiostratigraphic correlations and assumed minimum diachrony of biostratigraphic events.
