Write a paper of 910 pages, doublespaced, not including illustrations or references discussing the stratigraphic, tectonic and climatic history of the southern Colorado River/ Colorado River Delta, Salton Trough region for the Late MiocenePliocene. Your paper should synthesize our current understanding of the evolution of the San Andreas Fault system and the integration of the Colorado River system as a throughflowing drainage to the Gulf of California, as evidenced by sedimentary sequences exposed in the lower Colorado River Valley, southern California and the Salton Trough. Organize your paper in a historical order, with older events in all areas grouped together prior to younger ones. The paper SHOULD NOT be simply a review of the stratigraphy at Anza Borrego that your classmates on the field trip are visiting. To help you get started here are some useful references. Your paper should draw on at least 5 published references (cited and listed in a bibliography in standard scientific formatalso not part of the 910 pages). Cited work should be actually USED in developing your argument, not just included to fulfill the 5 paper requirement. Avoid direct quotes from your cited sourcesput things in your own words. Although your paper cannot be just based on Anza Borrego that area is central for understanding the evidence you need to write your paper. Therefore I encourage you to join up with one of the lab groups of students who attended the field trip to make use of one or more of their measured sections to illustrate points in your paper. If you do this you should use their raw data and draft up your own section (don’t simply photocopy someone else’s work). This should not be a major component of your paper howevermost of the paper should be based on your literature review. Your paper should be in the following format Abstract (write this last, 200250 words) Introduction Data review (present the results of individual studies you have read) Discussion and synthesis (bring together the results of the various papers and look for points of agreement/controversy/areas where further research is needed)
