Abstract: A concise and factual abstract is required. The abstract should state briefly the purpose of the
research, the principal results and major conclusions.
Keywords: Provide a maximum of 6 keywords.
Introduction: State the objectives of the work. Relevant controversies or disagreements in the field
should be mentioned so that a non-expert reader can delve into these issues further.
Background: Provide an adequate background. You should supply sufficient background information to
allow the reader to understand and evaluate the results without referring to previous publications on the
topic. As you compose the introduction, think of readers who are not experts in this field.
Material and methods: Provide sufficient detail to allow the work to be reproduced. Protocols for new
methods or significant modifications to existing methods should be included. Studies presented should
comply with our recommendations for distribution of materials and data.
Results: This section should provide statistical analyses of all of the experiments that are required to
support the conclusions of the paper. Present the results as concisely as possible in text, table(s), or
figure(s). Avoid extensive use of graphs to present data that might be more concisely presented in the text
or tables. Limit photographs to those that are absolutely necessary to show the experimental findings.
Number figures and tables in the order in which they are cited in the text, and be sure to cite all figures
and tables.
Discussions: This should explore the significance of the results of the work. The Discussion should

provide an interpretation of the results in relation to previously published work. It should not contain
extensive repetition of the Results or reiteration of the Introduction. This section should spell out the
major conclusions of the work along with some explanation or speculation on the significance of these
conclusions.
Conclusions: The main conclusions of the study may be presented in a short Conclusions section, which

References: Please ensure that every reference cited in the text is also present in the reference list (and
vice versa). Examples: "as demonstrated (Allan, 1996a, 1996b; Shi and Shen, 1998). Cung et al. (2000)
have recently shown ....". References in the alphabetical list should be in the form of the following
example: Cung Thuong Chi, Nguyen Quoc Cuong, Nguyen Trong Yem, 2000. Preliminary paleomagnetic
results of Late Permian-Early Triassic basalts from northwestern Vietnam and their tectonic implications.
Journal of Geology, A/259, 1-8. (In Vietnamese).
Shi, G.R., Shen, Shu-zhong, 1998. A Changhsingian Late Permian brachiopod fauna from Son La,
northwest Vietnam. Journal of Asian Earth Sciences 16, 501-511.
Appendices: Please add appendices if it is necessary.
