Fire Island, September, 2015 (courtesy Christa Shen)
An overview of sedimentology and stratigraphy, for majors and concentrators in Earth and environmental sciences, and for graduate students from other disciplines. Undergraduates in such related fields as Earth and environmental engineering, environmental biology, environmental chemistry, sustainable development and archaeology are also welcome. Lectures/class discussions, labs. and field exercises are integrated, with emphasis on processes, the characteristics of sediments and sedimentary rocks, interpretation of the geological record, and practical applications.
To inspire an appreciation for sedimentary phenomena and the interpretation of Earth's sedimentary record.
The course builds upon material covered in EESC UN2200 Solid Earth System and other courses at a comparable level. Participants in EESC UN1010 Geological Excursion to Death Valley, California have seen examples of diverse sedimentary settings. Completion of EESC GU4113 Mineralogy is useful, but not assumed, to accommodate sophomores and juniors in Earth science as well as students on other tracks. Sedimentary Geology is offered in alternate years (next in Fall 2020).
Saturday, September 12, to Fire Island (1 day).
Friday to Sunday, September 22-24 to the Hudson Valley and Catskill Mountains (3 days).
Departure from 116th and Broadway at 8:00 a.m., returning by 6:00 p.m. on the first trip. Departure from Lamont (Geoscience) at 8:45 a.m. on the second excursion, returning to Columbia by 8:00 p.m. Transportation to Lamont via shuttle bus (free with Columbia ID). We plan to camp at Kenneth L. Wilson Campground and at Thompson's Lake State Park in the Catskill Mountains on the second trip (weather permitting). Participation is required (and well worth the time invested!). Rain dates are September 10 and October 13-15.

Students are asked to complete assigned readings ahead of class. (Check Courseworks for details.)
Grades will be based on mid-term (20%) and final examinations (40%), field projects (20%), and an assessment of each student's contributions to the class (20%). Questions in exams will be based in part on lab and field activities. Graduate students may request R-credit (lectures and field trips only; no labs or exams.), or participate sporadically (no credit). Only full participation counts towards the required course point total.
Lectures: TuTh, 2:40-3:55 p.m., Schermerhorn 506

Nicholas Christie-Blick is a Professor and former Chair of Earth and Environmental Sciences, and has been at Columbia University since 1983. He holds degrees in geology from the University of Cambridge, U.K. (B.A., 1974) and the University of California, Santa Barbara (Ph.D., 1979), and prior to joining Columbia was for three years a research geologist with Exxon in Houston, Texas. He teaches courses in sedimentary geology and tectonics, receiving the Best Teacher Award in Earth and Environmental Sciences in 1996 and 2008 from the department's Ph.D. students, and in 2010 from the undergraduates (the inaugural year of that award). Christie-Blick's research deals with sedimentation processes, crustal deformation, and deep-time Earth history.
Michael DeLuca is a second-year Ph.D. student in the Department of Earth and Environmental Sciences. He received a B.S. in Geology from Union College in 2013, with a senior thesis involving integrated zircon fission track and LA-ICPMS techniques to constrain the thermochronologic history of Nagai Island, Alaska. Prior to arriving at Columbia, he earned an M.S. in Geology at Texas A&M University using zircon ID-TIMS U/Pb techniques to establish a chronostratigraphic framework for the Eagle Ford Shale. His current research is making use of detrital 40Ar/39Ar geochronology to investigate the provenance and tectonic context of the Devonian Old Red Sandstone in Scotland. At Texas A&M, Michael acted as teaching assistant for Physical Geology and Petrology.
