Geol 2312 Petrology Writing assignment Igneous settings and processes in the literature One way to learn about igneous processes is to read papers about them from the scientific literature. For this assignment, you will select a paper published in the journal Elements to summarize and critique. The assignment will give you the opportunity to learn and report about the nature, tectonic setting and geochemical features observed in actual magmatic provinces around the world. This will also give you the opportunity to practice becoming a critical reader. Elements papers are usually short and address timely issues in petrology and geochemistry. They are often written with students in mind, so they are tractable and don’t drag on forever. On the other hand, they can be densely written and might assume a good deal of knowledge or understanding. So don’t take for granted that because it’s short you can breeze through it in a short time. Often, Elements papers, whether good or bad, take several readings to feel confident about the content. For this assignment, you can choose from among various papers published in Elements on the general topic of igneous process. These can be found on the Moodle course website and downloaded. What topic should you pick? That is entirely up to you and your interests! I suggest reviewing the titles and abstracts of a few papers from the list (next page) and pick one that appeals to you. It might be something related to a feature or process that struck you as particularly interesting during your reading, or perhaps you want to find out more about the igneous geology of a particular geographic area, or you might want to focus on a currently active volcanic setting to learn more about what makes that area tick. Write a short evaluation (approximately 500 words, or up to 2 pages, double-spaced) of this paper. The evaluation should start with (a) a summary of the main point or main findings of the research, and (b) a critique of the written presentation (quality of writing, effectiveness of arguments, clarity of graphics, organization, ability to convey the science, etc.). Be sure to identify the authors, title, and date in a full literature citation of the paper you are reviewing. Put this at the top of your paper. This paper is due in hard copy, by Wednesday, March 25 in class. You will be graded on the basis of your critique and the quality of your own writing. I suggest the following general format: 1. A brief summary of the main point of the paper. What were the author(s) trying to convey? Why is it important? 2. A critique of the presentation. How is the writing? Are the diagrams clear and useful to your understanding? Does it assume too much? Are the conclusions and interpretations supported, by the data presented?
