These structures formed in response to an older north-oriented shear couple and a younger east-west-oriented tension. Laramide orogenic movements of late Paleocene through Eocene age resulted from a north-trending, right-shift force couple related to northeast shift of the Colorado Plateau. The folds and the northeast-trending normal faults formed in response to the right-shift couple, and the faults are interpreted as tensional fractures that developed at 45° to the trend of the couple. Miocene to Holocene tectonism is dominated by north-trending, east-dipping normal faults related to the development of the Rio Grande rift. Many southeast-dipping normal faults of Laramide origin were rejuvenated during Miocene and younger rifting. This content is PDF only. Please click on the PDF icon to access.
