Overturned Fold

Science / Geology / Overturned Fold: A fold that has both limbs dipping in the same direction, resulting from one of those limbs being rotated through an angle of at least 90 degrees. Overturned folds are found in areas of intense deformation. The name overturned is given because the strata on one limb of the fold are 'overturned' or upside down.
