The Powell Valley example of this type of structure provided much of the evidence for the Rich model of bedding-step faulting. The Hudleston Classification Scheme assigns their corresponding forms an alphanumeric value based on their flatness and angularity. These features often contain Saddle reef deposits or structural traps that harbor mineral deposits or oil below their culmination points or hinge zones. Isoclinal rec
The Powell Valley example of this type of structure provided much of the evidence for the Rich model of bedding-step faulting. The Hudleston Classification Scheme assigns their corresponding forms an alphanumeric value based on their flatness and angularity. These features often contain Saddle reef deposits or structural traps that harbor mineral deposits or oil below their culmination points or hinge zones. Isoclinal recumbent versions are often a result of long duration pressures typical in mountain belts, while briefer events such as salt-doming result in diapiric ones. On a geologic map, they are indicated by opposing arrows that point away from their axial traces. The Purcell is one grouping of them in British Columbia, and the Hercynian Orogeny uplifted a chalk one that once connected Weald to Artois. FTP, name these geological structures, convex-upward folds with their oldest strata downwards, which are often flanked by similarly named convex-downward structures.
