LITHOLOGICAL AND MINERALOGICAL PECULIARITIES OF CARBONATE ROCKS IN THE UPPER TOURNAISIAN SUBSTAGE AT THE ALEKSEEVSKY OIL FIELD

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2018
At the present stage of the development of geological sciences more detailed lithological and petrographic studies become more important. Microscopic studies of core material in the Upper Taurus substage made it possible to isolate the lithotypes of ...

Biostratigraphic Study of the Gurpi Formation Based on Planktonic Foraminifera In Lar Area (Kuh-e-kurdeh Section) [PDF]

open access: yes, 2009
The study of planktonic foraminifera of the Gurpi formations at Lar area (Kuh-e-kurdeh section) enables me to find the most standard biozones defined in mediterranean regions, especially Tethysian domain. Five biozones were determined.

Foraminifers associated with macroalgae on a wave-cut platform off Abu Qir coastal area, Egypt

open access: yesEgyptian Journal of Aquatic Research, 2022
Since their earliest history, benthic foraminifers have diversified to inhabit a vast array of habitats, from semi-terrestrial to the deep-sea floor. Epiphytic foraminifers developed morphologies that have allowed them to inhabit macroalgal fronds and ...

Phenotypic Evolution in a Cretaceous Foraminifer [PDF]

open access: yesEvolution, 1982
Statistically well-documented sequences of fossil species are rare, as has been observed, for example, by Eldredge and Gould (1972), Boucot (1978) and Dodson and Hallam (1977). Rapid advances in theoretical paleontology made over the last few years have, however, made it imperative that the many new and exciting theories we now have at our disposal be ...

Oceanographic parameters in continental margin of the State of Ceará (northeastern Brazil) deduced from C and O isotopes in foraminifers

open access: yesAnais da Academia Brasileira de Ciências, 2007
Specimens of Recent foraminifera of Amphistegina radiata, Peneroplis planatus and Globigerinoides ruber, from fifty samples of surface sediments of the continental margin of the State of Ceará, Brazil, have been analyzed for carbon and oxygen isotopes to

Variations of porosity in calcareous sediments from the Ontong Java Plateau [PDF]

open access: yes, 1993
Based on index properties measurements made on board the JOIDES Resolution, we studied porosity changes with depth in the fairly homogeneous deep-sea calcareous sediments cored during Ocean Drilling Program Leg 130 on the Ontong Java Plateau.

An Aberrant Foraminifer [PDF]

open access: yesNature, 1871
I CHANCED upon an aberrant form of Peneroplis the other day, in which the free terminal series of chambers of this Foraminifer, ordinarily single, is constricted into two distinct tubes.
