In a fold-thrust belt a décollement is the lowest detachment and they are responsible for duplex formation, which evolution and geometry vary in styles and greatly influence the dynamics of thrust wedges.
In a fold-thrust belt a décollement is the lowest detachment and this type of structure can form in the foreland portion of a classic fold-thrust belt. They are responsible for duplex formation, which evolution and geometry vary in styles and greatly influence the dynamics of thrust wedges.
