Information for Contributors

Submission of a paper implies that it has not been published previously and is not under consideration for publication elsewhere.

Typescript. All parts of the paper must be typed double-spaced on good quality white paper A4 (210 x 297mm) with at least 2.5 cm margins at top, bottom, and sides. Each page of the typescript should be numbered on the bottom in the right corner.

Authors are expected to supply 2 clean copies in English or Bulgarian. Please use correct English or Bulgarian spelling, punctuation, grammar, and syntax. The metric system must be used throughout; use of appropriate SI units is encouraged.

Paper length. Paper should be written in the most concise form. Occasionally long papers (over 15p.) are accepted, particularly those of a review nature.

The typescript should be arranged as follows:

1. Title page including authors' names and affiliations

2. Abstract and key words

3. Text (including tables and figures)

4. Reference list

Abstract. The abstract should be in a single paragraph (250 words or fewer). State the nature of the investigation and summarize its important conclusions. References must not be cited in the abstract. The abstract should be suitable for separate publication in a Web site.

Mathematics. All characters available on a standard typewriter must be typewritten in the equations as well as in text. Special attention should be paid to single couples of the kind: vn , pr , mm , nh .Distinction should be made between the letter O and the numeral 0; between the letter l and the numeral 1; between k and kappa.

Alignment of symbols must be unambiguous. Superscripts and subscripts should clearly be in superior or inferior position. Fraction bars should extend under the entire numerator. Displayed equations should be numbered consecutively throughout the paper; the number (in parentheses) should be to the right of the equation.

References. A complete and accurate reference list is of major importance. Only works cited in the text should be included in the reference list. References are cited in the text by the last name of the author and the year: (Jones, 1990). If the author's name is part of the sentence, only the year is bracketed. References are arranged alphabetically by the last names of authors. Multiple entries for a single author are arranged chronologically. Two or more publications by the same author in the same year are distinguished by a, b, c after the year

Tables. Tables should be typed as authors expect them to look in print. Every table must have a title. Column headings must be arranged so that their relation to the data is clear. Each table must be cited in the text.

Illustrations. All illustrations should be inserted in the text, suitable for the camera-ready reproduction (which may include reduction). Each figure must be cited in numerical order in text and must have figure legend. Please do not draw with hairlines. The minimum line width is 0.2 mm (i.e. 0.567pt).

Electronic submission. Authors must submit an electronic copy of their paper with the final version of the manuscript. The electronic copy should match the hardcopy exactly.

Authors will receive more detailed information when the article is accepted for publication so that requirements for the camera-ready presentation are fulfilled.

 

Instructions for Preparing Camera-Ready Manuscripts

General requirements

The manuscripts for Bulgarian Geophysical Journal (BGJ) (camera-ready) should be prepared according to the following specifications:

  1. BGJ size is not standard. Please set your Word processor to the following page dimensions (on the File menu click on Page Setup, then click the Paper Size tab. Select the Custom Size and type the values): width 165 mm (6.5"), height 238 mm (9.4").

  2. Margins: Top 25 mm (0.98"), bottom 20 mm (0.79"), left 17.5 mm (0.69"), right 17.5 mm (0.69");

  3. Use font Times New Roman for the text in Latin and Times New Roman Cyr for the text in Cyrillic. In case you do not have this font use another font from the same group, maximally approaching Times New Roman. If you work with Word 2.0 you can use Timok or Hebar for the text in Cyrillic.

    Important: If you are using another font this may cause undesirable changes in the article presentation.

  4. 4. For comparison please use the "Sample document" which can be received from the editor's office.

  5. You can use the document template named “Sample document BGJ” as well. All styles used in Bulgarian Geophysical Journal are attached to the template. The style names begin with 01, 02, 03… 16. Here is a list of styles used in Bulgarian Geophysical Journal:
    - 01Title BGJ - 09Text no First Line
    - 02AutorsBGJ - 10Acknowledgments

  6. Please do not use footnotes. You can give explanations in brackets within the text.

  7. The measuring units determining the size of page, margins, fonts, etc. can be given in inches, millimeters or points. For information: 1 inch = 25.4 mm; 1 pt = 1/72 inch.

  8. Each page of the manuscript should be enumerated by hand on the top right angle. These numbers will not appear in the publication.

  9. Please do not insert a blank space between the different paragraphs of the document (for example between title and author, between author and address, etc.) by pressing ENTER. Set the distance on the Format menu, click on Paragraph and type the necessary values in the boxes Before and After (or apply the appropriate style from Format menu > Style > Name of style).

  10. Definition of the expressions: ”Leading” or “Line spacing” –the space between lines. On the Format menu, click on Paragraph, and type the necessary values in the box “Line spacing”.

  11. Please do not use font style bold in the article except for specific Symbols, vectors as well as titles, subtitles and references. If you wish to stress a certain word or phrase use italic type, larger type or capital letters.

Tables

Tables can be positioned either landscape or portrait. Dimensions of tables along the wide side of the page cannot exceed the following values: width 177.8 mm (7") and height 127.0 mm (5") together with the figure captions. If you change the page orientation replace the values for the height by the values for the width.

If two or more graphs are grouped in one figure, its height should be up to 177.8 mm (7") and width 127 mm (5") together with captions. The latter must be at 6 pt space above or below the figure, not wider than the figure itself. Space between figure together with caption and the text of the article (if there is one) must be equal on all sides: top and bottom, - 6 pt. Please place the figures where you want them to appear in the text. You can submit another electronic copy in ".jpg" or ".tif" format for each figure separately. The resolution of the picture file must be at least 300dpi (or above) and the picture size does match the size you want it to appear in the text. Please do not forget figures captions.

Citations

When citing please follow the two samples of this instruction.

Sample 1:

…In this region, higher densities in the mantle due to cooling across the fracture zone, serpentinized peridotites with a higher density than gabbros of the same velocity (Miller et al., 1997).

Sample 2:

…Using elastostatic theory, Weertman (1971a), Secor and Pollard (1975) and Pollard (1976) have shown that vertical finite-volume fractures containing …

If you cite two or more works of the same author (authors) of the same year, place small letters a, b, c…after the year. When arranging the reference list follow the alphabetical order of authors' names and the first word of the article or book head/title and do not forget to place the same small letter after the year.

Running heads

On a separate sheet of paper give the shortened title of the article and the name(s) of the author(s) up to 80 symbols, spaces included, which will be used as running heads. The title-shortened variant must start with the same word as the original title.
