| Descripción: |
In the central Canadian Rocky Mountain thrust-fold belt, three types of first order decollements are outlined within or along the border of the present orogenic wedge: one basal decollement, three intermediate or internal decollements and one upper decollement. Structural relationships suggest that each internal decollement is the result of one of the successive forward shifts of early basal decollements to new positions within the stratigraphic pile. Two computer programs have been developed to analyze the propagation of multiple thrust faults and their influence on the geometry of a thrust belt. The computer programs generate graphical simulations used to demonstrate a model of thrust propagation and thrust belt development that fits current knowledge about fault propagation and can replace the thrust transfer zone concept. A structural analysis of mesoscale structures in two thrust sheets indicates that a thrust sheet consist of a series of elongated blocks separated by subtle brittle-ductile shear zones along which differential motion occurred. These shear zones are oriented perpendicular to the mean strike of the thrust faults. |
