Whitney, Christian Teyssier, Nicholas C.A. Seaton, Katherine F. Fornash University of Minnesota, Minneapolis MN Tectonics Introduction Table S1 contains the coordinates for samples used in this paper. Figure S2 contains pole figures with the orientation of crystallographic axes for quartz analyzed by electron backscattered diffraction (EBSD). 1.
