Speaking Mechanics • Giving a presentation is like acting • Body language is important • Make eye contact • Get the pace right • You’re NOT going too slow • Feel free to say nothing • Repetition and restatement
New evidence for sinistral transpression in the Cheyenne belt W. A. Sullivan, Colby College R. J. Beane, Bowdoin College
Compiled from Houston et al., 1968; Karlstrom and Houston, 1992; Houston and Graff, 1995; and Resor and Snoke (2005)
Reigning tectonic and structural model From Duebendorfer and Houston, 1987
Strain modeling of transpressional shear zones predicts: • Steeply dipping foliation • Subvertical lineations and/or • Strain in the flattening field Undeformed Deformed
Asymmetrical boudins at Bear Mountain locality Sinistral S-C fabrics at North Fork locality Image is 6.4-cm wide
Take-home points • Several areas of Cheyenne belt exhibit significant evidence for sinistral transpression • Cheyenne belt shear zones may have started life as a sinistral transpressional fault system
