... exposed for ∼70 km in adjacent Laramide uplifts of the southern Sangre de Cristo Mountains. Near the village of Guadalupita, these rocks display a smooth but abrupt south-to-north change from subhorizontal to subvertical dominant foliation (S 2 ) over a distance of ∼2 km. This change in dominant fabric...
