Calcareous nannofossils

1996
Abstract This chapter deals with calcareous nannofossils or coccoliths. These range in size from 1-100 µ,. Preparation of samples for calcareous nannofossil study generally consists of pulverising the containing sediment in distilled water using a pestle and mortar, strewing some of the suspended mixture onto a slide using a pipette and ...

Oligocene Calcareous Nannofossil Provinces

1974
Abstract Investigations of modern calcareous nannoplankton and their fossil record have shown that the distribution of coccoliths in marine sediments is influenced by latitudinal provinciality, neritic or oceanic habitat selection, selective solution, and diagenesis.

Mesozoic calcareous nannofossils — state of the art

Paläontologische Zeitschrift, 2005
Calcareous nannofossils originated in the Triassic, radiated in the Jurassic and became a dominant component of the marine biosphere from the earliest Jurassic onward. They can be considered as one of the most important “innovations” of the Mesozoic oceans.

Extraction Techniques for Calcareous Nannofossils

2001
This group comprises a heterogeneous collection of organisms, or their disaggregated parts ranging up to 201.tm in size. The most common examples encountered in residues are coccoliths; the basic elements of chrysomonad flagellates. Coccoliths are button shaped rings arranged in a complex manner forming hollow spheres (coccolithospheres).

Volume calculation of Paleocene calcareous nannofossils

2008
During the past decades, volume calculation of extant calcareous nannoplankton has been performed in order to convert coccolith fluxes data into carbonate export productivity. The most useful and relative recent method to estimate the volume of coccoliths is described by Young & Ziveri (2000).
