Long Demonstrations, Set #1

Session #1 (Sunday 10:30) , repeated in Session #5 (Thursday 8:30)

L1A: Venus, Earth's Structural Sister: Investigations using radar imagery (Vicki Hansen, University of Minnesota, Duluth). Ever dream of an entire planet with ~100% structural exposure (no nasty sediments, biology, or obfuscating water)? Venus is the place! We'll use Magellan radar imagery (regular and synthetic stereo) to examine planet-scale structure- tectonic problems for classroom use. Concepts include remote data set interpretation, structure morphology and interaction, rheology, large-scale planet processes and more.

L1B: Physical Experiments Demonstrate the Relationship Between Strain, Stress, and Rheology (Basil Tikoff, University of Wisconsin). A major conceptual jump for many students in structural geology is making the connection between theoretical idealizations (stress, strain, rheology) and physical reality (rocks). Physical models are an excellent bridge in relating these two, because the boundary conditions and the material behavior are simplified. Further, the material deformation is directly observable, and a concept of progressive deformation is reinforced. This session will use an exercise that employing simple, hands-on physical models to provide an intuitive feeling for strain, stress, and rheology, and allows some quantification of these parameters.

L1C: Hypothesis Testing and Breakin' Rocks (Michelle Cooke, University of Massachusetts). In its coulomb criterion form, rock strength discussions can become bland and tedious. Analog devices can revive rock strength conversations by allowing students to witness real rocks break; furthermore, students can collect their own strength data to test self-developed hypotheses. This session will demonstrate a rock failure experiment and provide ideas for integrating rock strength hypothesis testing with Schmidt hammers, uniaxial compression rigs or rock core splitters into structural geology courses.

L1D: Using "An Introduction to Structural Methods" - An Interactive CD-ROM - In and Out of the Classroom (Tekla Harms, Amherst College). This session will explore innovative uses of this CD-ROM (available from Tasa Graphic Arts, Inc.) in support of teaching and learning in structural geology. Intended to supplement rather than replace conventional texts and lectures, this tool seeks to bring the best attributes of the medium to bear to enhance understanding in structural geology by supporting topics richly with color maps, 3D diagrams, and animations. Many of the resources on the CD are appropriate for classroom presentation, but the subjects covered are presented in an instructional format and include interactive exercises so that students can also use the CD for self-directed inquiry.

L1E: Composite session on fracture experiments with the following 6 short presentations:
