Manuscripts are to be printed in English and double spaced, on one side of A4 paper. The original and two copies of the manuscript together with the originals and two sets of copies of the figures should be submitted for review purposes. Papers are not to exceed 8000 words nor to contain more than 7 figures and tables. Large figures and tables should be avoided, and their width should generally be either 8cm, 16.5cm or 24cm. Each illustration should be clearly drawn and lettered.

SI units should be used.

State secrets are not to be released. Permission must be obtained for the use of copyrighted or previously published material. Authors take full responsibility for their papers.

We accept only unpublished, original papers, and claim first right of publication. Papers unsuitable for JCUG will be returned promptly.

Manuscripts should be organised in the following order: (a) Title; (b) Name(s) and affiliation(s) of Author(s); (c) Abstract (no more than 200 words) and key words (no more than 8); (d) Introduction; (e) Methods, techniques, studied material and area descriptions; (f) Results; (g) Discussion; (h) Conclusions; (i) Acknowledgments; (j) Explanation of plates; (k) References cited; (l) Tables; (m) Figure captions.

Headings
The following sequence should be used:
a. Free-standing capitals, bold, at the margin
b. Free-standing lower-case, bold, at the margin
If a further subdivision is needed, 1, 2, 3, etc., or (1), (2), (3), etc.,or a, b, c, etc., should be used.

References
All references cited to publications made in the text should be presented in a list of references following the text. The manuscript should be carefully checked to ensure that the spelling of authors' names and the publication dates are exactly the same in the text as in the reference list.

If reference is made in the text to publications written by more than two authors the name of the first author should be given, followed by "et al.". In the list of references, the names of the first three co-authors should be given, followed by "et al.". References should be arranged alphabetically by authors' names and chronologically per author.

The following system should be used for arranging references.

1. For periodicals:
   Chough S K, Barg E, 1987. Tectonic History of Ulleung Basin Margin, East Sea (Sea of Japan). Geology, 15(1): 45-58
2. For books:
   Shrock R R, 1948. Sequence in Layered Rocks. New York: McGraw-Hill. 507
3. For edited books:

4. For edited symposia, special issues, etc., published in a periodical:

   Periodical names should be given in full or abbreviated using the International List of Periodical Title Word Abbreviations. In addition, in referring to a personal communication the two words are followed by the year, e.g. (MeNary J., personal communication, 1968).

Footnotes
Footnotes should only be used if absolutely essential. If possible the information should be incorporated in the normal text. If used, footnotes should be indicated by asterisks and kept as short as possible. If references are given in footnotes, full bibliographic data must be given in the list of references, not in the footnote.
All manuscripts should be governed by the above information. Otherwise, publication of articles can be seriously delayed because of corrections.
Please send manuscripts to: Journal Editorial Office, China University of Geosciences, Yujiashan, Wuhan 430074, People's Republic of China.
