Analogue Microstructural Modelling at the University at Albany, State University of New York Youngdo Park, Jin-Han Ree & Win Means
Introduction There are several time-lapse movies linked to this playlist, which show the experimental deformation or post-deformation behaviour of octachloropropane (C3Cl8). Most of the experiments on this page were performed during December 1995, when JHR was visiting Albany. Feel free to download these movies for teaching. The order of the movies is such that the experimental strain rate decreases and temperature increases. Octachloropropane (OCP hereafter) is an organic material with hexagonal crystal symmetry. Polycrystalline OCP shows "similar(?)" microstructures to those found in quartzite. The material has been used to study various deformation processes by many workers (Win Means, Janos Urai, Mark Jessell, Jin-Han Ree, Paul Bons, Coen ten Brink, Cees Passchier), and is probably being used for the same purpose, even now somewhere on Earth (see Ree, 1994, J. Struct. Geol. vol. 16, 403-418http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V9D-48C8RJ4-3X&_user=929460&_coverDate=03%2F31%2F1994&_alid=1405823163&_rdoc=2&_fmt=high&_orig=search&_cdi=5896&_sort=r&_docanchor=&view=c&_ct=7&_acct=C000048339&_version=1&_urlVersion=0&_userid=929460&md5=b93c9c75c16c74f0f21b8d69d090237b for details of the experiments). Nearly simple shearing grips (grips imposing simple shearing with a small "transpressional" component) were used for deformation, except in Movie 04 which shows a pure shear deformation experiment.
The horizontal dimension of the movies is ~1.5 mm.
