Document Summary
Cylindrical vs non-cylindrical folds: cylindrical folds have a fold axis, non-cylindrical curved hinge line. Antiform vs. synform: antiform; concave up, difference b/w form and cline. W/ anticline the old lies at the core the synform and antiform refer to the shape an antiform can also represent a syncline: if younger at the core and concave down. This occurs when layers are overturned resulting in a different shape contrasting with the younging direction. Interclinal: 2 limbs less than 30: isoclinal. Kink and chevron: if one limb is longer than the other it is called a kink fold, if the limbs are of equal length then they are called chevron folds.
