G435 Sedimentology and Stratigraphy
Class Assignment #2
*This is assignment is now extra credit. If you do not complete it, it will not hurt your grade. If you do
complete it satisfactorily, you will receive up to +5 points on your final exam.
This assignment is due Friday, December 1st.
Goal: Investigate usage of stratigraphy in the scientific literature and develop an understanding of how
it is applied. Practice searching for relevant scientific references and distilling main points of an article.
Assignment: Find a published, peer-reviewed article that uses stratigraphy in a scientific investigation (I recommend using Google Scholar). The paper should have a figure that shows some sort of stratigraphic correlation. Please complete a one page write-up that includes the following:
1) Your name 2) Full citation of the article (use APA format) 3) A paragraph summarizing the main points of the article 4) A paragraph with your own reaction / opinions (What did you think? Are there parts that were
especially interesting to you? Parts you did not agree with? Parts you thought were confusing?) 5) A sentence that states the type of stratigraphic correlation used (lithostratigraphy,
chronostratigraphy, seismic stratigraphy, magnetostratigraphy, biostratigraphy, etc.) 6) On the back (or a separate sheet of paper), include a screenshot of a figure from the paper that
shows the stratigraphic correlation in #5
