Definition of Foreland
For purposes of this presentation, the foreland is defined as the area bounded by the undeformed craton and the fold and thrust belt of the geosynclinal area. Foreland areas can display varying tectonic styles based upon the previous plate tectonic history. Some foreland areas will have only extensional tectonic characteristics, resulting from the early history of a passive margin, while others will have been subsequently deformed and display a different style.
Figures & Tables
This publication begins with the basics of definition and description of a foreland, and in particular North American foreland areas. It then goes into detail on Rocky Mountain foreland areas, covering general information, age of basement complexes, basement rock types, angles of basement faulting, contrast of structural concepts, predominant structural styles, and drape versus dynamic folding of sediments.
