8. Submission

A pdf file including text and figures should be submitted by e-mail (a.anceau@ulg.ac.be).

Alternatively, three printed copies may be submitted to the editor together with the address of the corresponding author (fax, e-mail). Original artworks are not necessary for the submission of the manuscript.

The authors are requested to give the names and addresses of four possible unbiased reviewers, at least one of them being chosen outside Belgium.

9. Final version

9.1. Text

Send all files (text, artworks, tables) by mail or on a CD to the editor. Each artwork as a separate file.

The requested software is Word and .doc format. Use the TIMES 12 throughout the text including titles.

Use the same file for text, references and artwork captions; these should not be included in the text or merged with the figures, but put together at the end of the manuscript and presented as follows:

Figure 1.Caption

Table 1.Title ...

Plate 1.Title ...

9.2. Original artworks

Please note that Geologica Belgica being an open access journal, the final size of a paper in pdf format must permit easy dissemination by e-mail. Thus the number and size of figures and plates must be reasonable.

No original artwork should be larger than a page (17 x 22.5 cm) or a column (8 x 22.5 cm). No lettering should be smaller than 1 mm at journal format. Artworks are executed neatly in black China ink or equivalent quality (e.g. laser printer); do not use heavy plots; avoid grey-tones. Figures in colour are accepted. Please save space as much as possible.

Electronic figures should be in ai (Adobe Illustrator), and/or pdf format. All elements of a figure must be "grouped" before saving. No graphics in Excel format will be accepted. Please try to use the same format for all figures. Do not mention the figure number on the figure. Do not group the figures but provide one file for each figure and table.

9.2.3. Running title (top of each page)

In case the title of the paper is longer than 60 characters including space, the authors should provide an abbreviated title.

10. Proof

A proof will be provided, but author's corrections will not be accepted.

11. References

The journal names should be written in full. Follow scrupulously the examples below, and DO NOT leave a blank line between each reference:

8. Submission

A pdf file including text and figures should be submitted by e-mail (a.anceau@ulg.ac.be).

Alternatively, three printed copies may be submitted to the editor together with the address of the corresponding author (fax, e-mail). Original artworks are not necessary for the submission of the manuscript.

The authors are requested to give the names and addresses of four possible unbiased reviewers, at least one of them being chosen outside Belgium.

9. Final version

9.1. Text

Send all files (text, artworks, tables) by mail or on a CD to the editor. Each artwork as a separate file.

The requested software is Word and .doc format. Use the TIMES 12 throughout the text including titles.

Use the same file for text, references and artwork captions; these should not be included in the text or merged with the figures, but put together at the end of the manuscript and presented as follows:

Figure 1.Caption

Table 1.Title ...

Plate 1.Title ...

9.2. Original artworks

Please note that Geologica Belgica being an open access journal, the final size of a paper in pdf format must permit easy dissemination by e-mail. Thus the number and size of figures and plates must be reasonable.

No original artwork should be larger than a page (17 x 22.5 cm) or a column (8 x 22.5 cm). No lettering should be smaller than 1 mm at journal format. Artworks are executed neatly in black China ink or equivalent quality (e.g. laser printer); do not use heavy plots; avoid grey-tones. Figures in colour are accepted. Please save space as much as possible.

Electronic figures should be in ai (Adobe Illustrator), and/or pdf format. All elements of a figure must be "grouped" before saving. No graphics in Excel format will be accepted. Please try to use the same format for all figures. Do not mention the figure number on the figure. Do not group the figures but provide one file for each figure and table.

9.2.3. Running title (top of each page)

In case the title of the paper is longer than 60 characters including space, the authors should provide an abbreviated title.

10. Proof

A proof will be provided, but author's corrections will not be accepted.

11. References

The journal names should be written in full. Follow scrupulously the examples below, and DO NOT leave a blank line between each reference:

Abstract

The Paleogene greenhouse world comprises variable paleoclimate conditions providing an indispensable deep-time perspective for the possible effects of human-induced climate change. In this paper, paleotemperature data of the Early Eocene Climatic Optimum (EECO) from the mid-latitude marginal marine Belgian Basin are discussed. They are derived from fish otolith δ18O compositions of four non-migratory species belonging to the families Congridae and Ophidiidae. Otoliths from several levels and localities within the middle to late Ypresian were selected. After manual polishing, bulk and incremental microsamples were drilled and analyzed by a mass spectrometer. A cross-plot of bulk otolith δ18O vs. δ13C results shows a discrepancy between both families used. Ophidiid data probably represent true bottom water temperatures of the Belgian Basin. The mean annual temperature (MAT) of the EECO is calculated at 27.5 °C, which is in line with other proxy results. However, variations in MAT up to 6 °C occur, suggesting a pronounced expression of climate variability in mid-latitude marginal basins. Incremental analyses revealed a ~9.5 °C mean annual range of temperatures, similar to modern seasonality. These results show that marginal marine environments such as the Belgian Basin are well suited to infer high-resolution paleoclimate variability.
