Unformatted text preview: Intuitive Sequence Stratigraphy: Replacing Lectures with Inquiry-based Computer Labs Dawn Sumner , Geology Department, University of California, Davis All undergraduate geology majors should understand the basics of sequence stratigraphy. However, complex terminology and diagrams commonly used to teach it act as barriers to an intuitive understanding of environmental shifts due to sea level change. These can be removed by teaching with graphically appealing computer models. Freeware Fuzzim (Nordland 1996, JSR v 66 p 689-698) and strategic questions teach basic sequence stratigraphy to sophomore and junior geology majors. Students adjust parameters and observe successive plots of sea level and sediment deposition/erosion in pseudo 3-d. Various sediment properties are plotted along user-chosen cross sections and Wheeler diagrams. Students gain an intuitive understanding of facies shifts, accommodation space, unconformity development, and gaps in the rock record in response to sea level change; they...
