- 1993, P. A. Cawood, “Acadian orogeny in west Newfoundland: Definition, character, and significance”, in David C. Roy, James William Skehan, editors, The Acadian Orogeny: Recent Studies in New England, Geological Society of America, page 138:
- The effects of Acadian orogeny are concentrated in central Newfoundland, decreasing in intensity to the east and west (Williams, this volume).
- 2004, Richard Fortey, The Earth, Folio Society, published 2011, page 102:
- When I asked Geoff Milnes what age the rocks were before they were turned into uncompromising gneisses by the Alpine orogeny he made a rueful face.
- 2009, Robert S. Hildebrand, Did Westward Subduction Cause Cretaceous-Tertiary Orogeny in the North American Cordillera?, Geological Society of America, page 5:
- In Canada the fold-thrust belt formed during what is termed the Columbian orogeny (Monger and Price, 2002). Because the Sevier and Columbian orogenies were contemporaneous and constitute a single continuous and linear belt of rocks and structures, I use the term Cordillera orogeny to refer to the Cretaceous deformation that created the entire belt, whereas the term Laramide is used only to refer to a series of Late Cretaceous—Tertiary basement-involved uplifts, for the most part located in the Rocky Mountain foreland east of the fold-thrust belt and mainly south of the Lewis and Clark lineament (Fig. 1) in keeping with the original definition by Armstrong (1968).
