Structural Geology Introduction The Manzano Mountains are located central New Mexico on the Manzano thrust belt east of the Rio Grande Rift. They formed during the paleo-proterozoic due to the Mazatzal Orogeny of Laurentia (Amato, Boullion, Serna, Sanders, Farmer, Gehrels and Wooden et al., 2008). Due to the subduction of a plate underneath Laurentia, pluton emplacement occurred along the Manzano Mountains. The emplacement of plutons occurred around 1.65 Ga and 1.4 Ga. (Bauer, Karlstrom, Bowring, Smith, Goodwin et al., 1993) The 1.4 Ga. Pluton is the Priest Pluton, which is located in the southern part of the Manzano Mountains. Field work was conducted in Estadio Canyon, located on the eastern side of the Manzano Mountains. The canyon runs through the contact aureole and the Priest Pluton. Several different lithologies are seen in the canyon, including metaryolite, metasediment, and amphibolites. Deformation in the canyon correlates to the shear zone of the thrust. Evidence of the shear zone
