Journal of the Geological Society of Sri Lanka (JGSSL)

Journal of the Geological Society of Sri Lanka (JGSSL) is a peer-reviewed and open access journal. It aims to publish the most topical and highest quality papers, summarizing the results of recent research across the full range of the Earth Sciences. Papers are frequently interdisciplinary in nature, often refer to regional studies and should emphasize the development of understanding of fundamental geological processes. The implications of regional studies should extend beyond their geographical context. Alternatively more specialized papers can be submitted, but they should be written in a style that is easily understood by non-specialists to illustrate the progress being made in that specific area of the Earth Sciences. Reviews on topics of current interest are also welcome, but they too should be written to cater for non-specialist readers. Specials are short papers on topical or controversial issues in Earth Sciences and receive fast-track reviewing procedures, allowing publication in less than 6 months.

The Journal of the Geological Society of Sri Lanka is published annually as a single issue, and the subscription price to institution and individual members is Rs. 500 (Sri Lankan) and US$ 30 (rest of the world). The journal will be dispatched by surface mail to all oversee subscribers.

Editorial correspondence and material submitted for publication should be addressed to the Editors, Geological Society of Sri Lanka. (email

Business correspondence including orders and remittance relating to subscription, advertisements, back issues and off-prints should send to the Treasurer, Geological Society of Sri Lanka. All cheques should be crossed and made payable to ‘The Geological Society of Sri Lanka’. (

Guide to Authors

 General Guidelines

Original research papers or review articles pertaining to any aspect of the geosciences in Sri Lanka or elsewhere are welcome. However, preference will be given to papers dealing directly with Sri Lanka and those with an international interest with relevance to Sri Lanka.

Manuscript (three copies) should be addressed to the Editors, Geological Society of Sri Lanka, c/o Department of Geology, University of Peradeniya, Peradeniya, Sri Lanka.

Papers are accepted on the understanding that they have not been submitted or published elsewhere.

If extra work on the manuscript is needed (such as figure redrafting) it will be charged to the author’s at cost.

The average length for papers, including references and text figures, should not exceed fifteen printed papers.

Papers will be refereed by at least two referees.

Authors should carefully follow the format used in a previous issue.


Three complete copies of text, tables, figure captions, photocopies of figures and one set of original photographs should be submitted, preferably by registered post.

Typescript must be accurate and in final format because corrections in proof stage are costly. Additions at proof stage will not be allowed.

Typescript should be double spaced, preferably on A4 paper and with a 2.5 cm margin on each side.

Papers should be arranged as follows: Title: brief and specific, followed by name(s) and address(es) of auth-or(s) including the email address of the corresponding author. Abstract: this must be intelligible without reference to the paper, and not more than 200 words. It should not be a mere recital of the subjects covered, but should be a condensation of the new information and interpretations in the paper. References should not be included. Main body of paper: subdivided into 1st, 2nd, 3rd and 4th order headings. All pages should be paginated and bear the name of the author(s). Acknowledgments: if any, to follow the main text. Tables: each typed on a separate sheet of paper. Captions: should be typed, double spaced, as a separate list and paginated separately. All illustrations are called ‘figures’ and referred to as “Fig.” in caption  and “Figure” in  text, except when in parenthesis.

References: list all references cited in full without abbreviations, and in alphabetical order. References in the text should be by name followed by year of publication; if more than one author use ‘et al.,’’ (follow format of a previous issue or contact editors).


The maximum printed size of illustrations is approximately 170×230 mm (full page) or 85x 230 mm (column width).

Originals should be in black ink on good quality tracing medium or white board. All drawings should contain a metric bar scale. Lettering should be minimum of 2 mm height after reducing, so should be large enough in originals to stand reductions.

Captions should not be written on the figures, and all empty space should, as far as possible be eliminated.

In maps, north point and, where possible, coordinates of latitude and longitude should be marked.

Large folded figures and maps will be accepted only after consultation with the Editors: authors may have to bear the cost of such folded insertions.

Photographs should be sharp, glossy prints, with good contrast, and contain some form of scale. All photomicrographs should contain a metric bar scale.

Separate parts of a single figure should be labeled a, b, c, etc. and so referred to in text and captions.

Name(s) or author(s) and figure numbers should be written on top, right-hand corner of line drawings, and on backs of photographs on stick-on labels. Where ambiguous, tops of figures and photographs should be indicated by an arrow showing ‘top’.


All publications cited in the text should be presented in a list of references following the text of the manuscript. Reference citation by the number system is not acceptable. The manuscript should be carefully checked to ensure that the spelling of authors’ names and dates are exactly the same in the text as in the reference list.

In the text refer to the author’s name (without initial) and year of publication, followed – if necessary by a short reference to appropriate pages. Examples: “Since Cooray (1996) has shown that …” “This is in agreement with results obtained later (Kröner et al., 1998, pp. 12-16)”. If reference is made in the text to a publication written by more than two authors the name of the first author should be used followed by “et al.”

Reference citations in the text should be arranged chronologically. This list of references should be arranged alphabetically on authors’ names, and chronologically per author. If an author’s name in the list is also mentioned with co-authors the following order should be used: publications of the single author, arranged according to publication dates – publications of the same author with one co-author – publications of the author with more than one co-author. Publications by the same author(s) in the same year should be listed as 1999a, 1999b, etc.

Use the following system for arranging your references (refer a recent issue of the journal if necessary):

Abbreviate the titles of periodicals mentioned in the list of references, according to the International List of Periodical Title Word Abbreviations.

In the case of publications in any language other than English, the original title is to be retained. However, the titles of publications in non-Latin alphabets should be transliterated, and a notation such as “(in Sinhala)” or “(in Japanese, with English abstract)” should be added.

Work accepted for publication but not yet published should be referred to as “in press”.

References concerning unpublished data and “personal communications” should not be cited in the reference list but may be mentioned in the text.

For a web based source, provide the name(s) of the author(s), the title of the report or article, the complete web address and the month and year the site was visited for the cited information.


Tables should be typed on separate sheets, not necessarily using double spacing.

They should be designed to go across single or double column width of the Journal. Units should be given once at head of table, and tables should be enclosed within rules.
