Nannofossils: the smoking gun for the Canarian hotspot

Geology Today, 2015
The origin of volcanism in the Canary Islands has been a matter of controversy for several decades. Discussions have hinged on whether the Canaries owe their origin to seafloor fractures associated with the Atlas Mountain range or to an underlying plume or hotspot of superheated mantle material.

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 ...

Nannofossils and biostratigraphy: An overview

Earth-Science Reviews, 1977
Abstract Intensive biostratigraphic studies of calcareous nannofossils have been carried out for only about a decade, even though nannofossils have been known for over a century. Although coccoliths have been reported from various Paleozoic deposits, datable assemblages are known only from Liassic (early Jurassic) and younger strata.

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.

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).
