Field evidence for the structural style of the Rocky Mountain forelands has been discussed by David W. Stearns. A series of seismic sections from Wyoming basins provides evidence that the same tectonic style exists in deeply buried structures. Most of the features shown are those formed as a result of high-angle basement faulting. The main limitation of seismic work for defining the structures is caused by the steeply dipping sedimentary rocks which drape over the high-angle basement blocks. The basement block-fault, drape-fold structural style is dominant in the Rocky Mountain foreland province. However, the seismic lines illustrate that other unrelated or indirectly related structural styles are present.
