Figure F4. Equal area lower and upper hemisphere contoured stereonets for plagioclase CPO (counting cone half-width = 15°). A. Sample 304-U1309D-64R-2, 43 cm. B. Sample 304-U1309D-64R-2, 46 cm. One point per grain (ensures a false CPO is not shown because of the oversampling of one large grain). First stereonet shows kinematic framework where foliation is east–west perpendicular to the page (Z = pole to foliation).
