拆离褶皱（Detachment Fold）

A detachment fold is a fold formed above the region in which the displacement on a lower detachment dies out (Jamison, 1987). The term detachment fold is used here as a general geometric concept for any fold formed above a stratigraphically fixed detachment horizon and that does not have displacement transferred out of the structure on an upper detachment. A detachment fold may have a wide variety of internal geometries and limb-dip relationships (Jamison, 1987; Mitra, 1992; Epard and Groshong, 1993).

拆离褶皱是在下部拆离的位移消失的区域之上形成的褶皱(Jamison, 1987)。这里使用“拆离褶皱”一词作为一个一般的几何概念，用于在地层固定的拆离层位之上形成的任何褶皱，这些褶皱的位移没有从上部拆离的构造中转移出来。滑脱褶皱可能具有各种各样的内部几何形状和四肢倾角关系(Jamison, 1987;密特拉,1992;Epard and Groshong, 1993)。
