Marine Micropaleontology 7, – Keller, G. The five-fold zonation of the Oligocene (Berggren and others, ) is modified to a six-fold zonation with the elevation of (former) Subzones P21a and P21b to zonal status.

    The planktonic foraminiferal zonation used in this report is the letter-number system developed by Banner and Blow () and Blow () for the late middle Eocene and Oligocene, and by Berggren (), as modified from Bolli (), for the Paleocene to middle Eocene.

Oligocene and Lower Miocene sediments of the Lučenec Depression were studied to demonstrate the planktonic bioevents and climatic proxies from the Číž Formation (Rupelian) and Lučenec Formation (Chattian-Aquitanian) on the basis of quantitative analyses of foraminifers and calcareous nannofossils.

BoxHouston, Texas ABSTRACT. chapter 2: tropical to subtropical planktonic foraminiferal zonation of the eocene and oligocene. Evaluation of modern planktonic foraminiferal rela- tionships and principles offers much toward the under- standing of differences between planktonic foraminif- eral zonation in different Cretaceous basins.

Methods of cross correlation employed may be made more precise in the light of this expanded understanding. ACKNOWLEDGEMENTSCited by: Try the new Google Books.

Figure F2 summarizes the integrated Paleogene geochronostratigraphy, emphasizing standard planktonic foraminiferal zones and datum levels from the (sub)tropics.

The P-zonation of Berggren et al. () has been correlated with the southern mid-latitude zones identified by Jenkins (,) and important datum levels. Atlas of Oligocene Planktonic Foraminifera.

The Paleogene Planktonic Foraminifera Working Group has been active over 25 years and dealing with comprehensive revisions to the taxonomy and biostratigraphy of Paleogene taxa.

The Atlas of Oligocene Planktonic Foraminifera (published ) represents the third, and final, contribution of this series. Based on correlation of these events with planktonic foraminiferal zonation, we find that this major erosional event took place at the time of a prominent eustatic sea-level fall 29 or 30 million years ago (Vail et al., ; Vail and Hardenbol, ).

The Eocene–Oligocene boundary is defined worldwide because of the change in planktonic foraminiferal assemblages across this datum. As recognized because of calcareous nannoplankton, the Eocene-Oligocene boundary at St.

The Foraminifera of the Kulapis Formation are arenaceous and undiagnostic benthonic of no stratigraphic value, for they range typically from Upper Cretaceous through Oligocene (Newton-Smith, ).However, Fitch () stated that shales in the Bode area near Sandakan contain an Oligocene .Less than one half of Middle Eocene to Miocene time is represented by the preserved sequences.
