A décollement horizon in tectonics is a surface that acts as a gliding plane between two masses in a thrust fault relationship. A décollement horizon can either form due to a low bulk modulus between bodies (usually in lithologies such as marls, shales and evaporites), or can form along planes of high pore pressures. [1]
