    1:44 Folding can be caused by an extensional regime, not only compressional

    isn't a drag fault associated with normal fault?? Cause you drew a reverse where HW moved up

      I assume you are thinking of a drag fold in which the drag is found entirely on one wall. Such a fold is only possible on normal faults. The example I used is on a reverse fault to illustrate the drag on both sides. Regardless of where exactly the drag appears, the key feature of a drag fold is simply one side being "dragged" beneath/behind the other, making it appear to overlap.
      Here are some images to illustrate my point:

      Reverse fault drag:

      Hope that helps!
