When you are writing the essay always remain conscious of the title/theme and stick to it. Ask yourself ‘what is the point of this particular line of reasoning/argument’ every time you put in some more facts or ideas. If it doesn’t really add much to the main thrust of the essay then consider dropping it. Always write in the third person; never use terms like I think, me, we, etc. The final point about essay structure – your essay should have a point! Ensure it has a section at the start introducing the topic and outlining the background and scope of the essay. The central sections then present the detailed evidence. The essay must then have a CONCLUSION(S) section at the end. This is perhaps the most important section of the piece as it should pull together all the elements of the essay and synthesize all your ideas, observations and interpretations into a
coherent argument.
It is very important that you properly reference your sources of information along the way. Use the formatting system of the Journal of the Geological Society of London and stick to it rigidly. That system employs a reference citation something like (Skywalker 1980), (Kenobi and Skywalker 1977) or (Vader et al. 2005) depending on the number of authors. Note: Christian name initials are not used in the main text and the et al. bit is italicized. Christian name initials do appear in the full citation list in the REFERENCES section at the end of the essay. Note in this list the use of small caps on the author names and that the (Skywalker 1980) reference is a book, so the title is italicized and the publisher (Hoth) left plain. The 99pp refers to the total number of pages in said book. There is also an indent on the second line of a reference citation.
