Stratigraphic measurements in parallel folds
Folded rocks having bedding surfaces which are approximately parallel are said to lie in parallel folds. Utilizing the principle of evolutes and involutes, the author offers a more precise definition of parallel folds and points out inconsistencies in other concepts. With the idea of classifying parallel folds and possibly of deducing the mechanics of their formation, methods are presented for obt
