   Fold and Thrust Belts
   Compressional forces result in the formation of fold and thrust belts, such as the Himalayas or the North American Cordillera. The geometry of these folds is frequently described using the Bifurcation Angle Index ($\beta$)/), which quantifies the angular relationship between the axial plane and the underlying décollement surface.
